The distance traveled by the Spacecraft is  2.3 x 10² m.

To have a constant velocity, the change in velocity or speed of the object must be zero.

Constant speed will elapse equal distance in an identical period of time as a result is an example of steady speed.

For a Spacecraft is traveling in inner planetary space at a constant velocity and a given time of motion, the distance traveled by the Spacecraft is calculated as follows;

Distance = speed x time

the speed is given as 24.21 m/s

the time of motion is given as 9.5 seconds

distance = 24.21 m/s  x 9.5 s

distance = 2.3 x 10² m

Thus, the distance traveled by the Spacecraft is  2.3 x 10² m.

Answer: 42 N-s

Explanation: The area under the curve is equal to the impulse, so you take the area of the two triangles and add it to the area of the rectangle.

Area of a triangle: 1/2bh

Area of a rectangle: bxh

2(1/2x2x7)=14+(4x7)=42 N-s

The force of magnitude F acting in the x-direction on a 3.5 kg particle varies in time as shown in the graph given in question, the impulse of this force is 42 N-s.

The integral of a force, F, over the time period  which it acts, t, is referred to as the impulse. Impulse is a vector quantity because force is one as well. When an item receives an impulse, its linear momentum also changes in the opposite direction in an analogous vector.

S.I unit of impulse is Newton-second (Ns).

From the graph given in question area under the curve is equal to the impulse, so  take the area of the two triangles and add it to the area of the rectangle.

Area of a triangle = 1/2bh

Area of a rectangle = bxh

total area,

impulse = 2(1/2x2x7)

             = 14+(4x7)

             = 42 N-s

Impulse of the force is 42 N-s.

Answer: 3 s

Explanation:

i took the test in physics :)

The time taken by the wave to travel the distance is 3 seconds.

What is meant by frequency of a wave ?

Frequency of a wave is defined as the number of oscillations or cycles completed by the wave within one second.

Here,

Distance travelled by the wave, d = 600 m

Wavelength of the wave, λ = 0.4 m

Frequency of the wave, f = 500 Hz

The expression for the velocity of the wave is given by,

v = fλ

v = 500 x 0.4

v = 200 m/s

Therefore, the time taken by the wave to travel the distance of 600 m can be given as,

Time taken = displacement/velocity

So,

t = d/v

t = 600/200

t = 3 s

Hence,

The time taken by the wave to travel the distance is 3 seconds.

The conductivity of a conductor refers to its ability to conduct electrical current.

A material that has high conductivity allows electrical charges to flow through it easily and with little resistance, while a material with low conductivity does not allow electrical charges to flow as easily and has more resistance.

The conductivity of a conductor is determined by the number of free electrons in the material, as well as how easily these electrons can move through the material.

In a conductor, the atoms are closely packed together and the electrons are not tightly bound to the atoms, allowing them to move freely through the material and carry an electrical charge. This facilitates the flow of electrical current through the material, resulting in high conductivity.

Answer:

Based on the information given, it is not possible to determine whether heat is being added to or removed from the system. However, we can make an inference based on the change in temperature. If the temperature increased from Time 1 to Time 2, then heat was likely added to the system, as particles gained kinetic energy and moved faster. Conversely, if the temperature decreased from Time 1 to Time 2, then heat was likely removed from the system, as particles lost kinetic energy and moved slower. Therefore, the statement that best describes how energy is changing between Time 1 and Time 2 is "Heat is being added to the system, so particles have more kinetic energy" or "Heat is being removed from the system, so particles have less kinetic energy," depending on the direction of the temperature change.

Eddy currents are closed electric current loops that are created when a conductor comes in contact with a magnetic flux that is fluctuating. They induce electromagnetic induction according to Faraday's law and produce closed circuits in a direction perpendicular to the magnetic field. These currents will move in the opposite direction of the Lenz law's needed shift.

When a conductor moves through a magnetic field or when the magnetic field around a conductor at rest varies over time, eddy currents are produced. They result from fluctuations in the direction and strength of a magnetic flux or conductor-linked field.

If the universe were to suddenly begin shrinking rather than continuing to expand, it would have a significant effect on the cosmic microwave background radiation (CMB).

The CMB is the afterglow of the Big Bang and is observed as a nearly uniform background radiation in all directions. It is thought to have been emitted when the universe was about 380,000 years old and had cooled enough for neutral atoms to form.

If the universe were to suddenly begin shrinking, the photons in the CMB would lose energy as they travel through the contracting space. This would cause the CMB radiation to shift to shorter wavelengths, which is known as blue-shifting.

Therefore, the correct answer is B. It would blue-shift.

In the figure provided, a 25.5° ramp in an airport has luggage sliding down to the owner.  If the ramp is 3.28 m long and the suitcase starts from rest, the time it will take for suitcase A to reach its owner is 1.25 seconds

The diagrammatic representation of the information given in the question is attached in the image below.

From the information given:

We are to find the time required for suitcase A to reach its owner.

To do this, let's compute the free body equation from the diagram.

Thus, both blocks tend to move together since the kinetic friction in A is larger than that of B.

So, summing up both equations, we have:

\(\mathbf{m_1 g sin \theta-m_2 g sin \theta - \mu_k_1 - \mu_k_2= (m_1+m_2)a}\)

Making acceleration a the subject, we have:

\(\mathbf {a = \dfrac{m_1 g sin \theta-m_2 g sin \theta - \mu_k_1 - \mu_k_2}{(m_1 + m_2)}}\)

\(\mathbf {a = \dfrac{(3.70 \times 9.8 \times sin25.5) +(9.69 \times 9.8 \times sin 25.5 )- 0.260 - 0.110}{(m_1 + m_2)}}\)

\(\mathbf {a = \dfrac{(15.610) +(40.88)- 0.260 - 0.110}{(3.70+ 9.69)}}\)

\(\mathbf {a = \dfrac{56.12}{(13.39)}}\)

a = 4.19 m/s²

Using the second equation of motion.

\(\mathbf{S = ut + \dfrac{1}{2}at^2}\)

Recall that the suitcase starts from rest;

∴

\(\mathbf{S = 0(t) + \dfrac{1}{2}at^2}\)

\(\mathbf{S = \dfrac{1}{2}at^2}\)

where;

\(\mathbf{3.28 = \dfrac{1}{2}(4.19) (t)^2}\)

By cross multiply;

3.28 × 2 = 4.19 t²

\(\mathbf{t^2 = \dfrac{3.28 \times 2}{4.19}}\)

\(\mathbf{t =\mathbf{ \sqrt{\dfrac{3.28 \times 2}{4.19}}}}\)

\(\mathbf{t =\mathbf{ \sqrt{1.566}}}\)

t = 1.25 seconds.

Therefore, we can conclude that it took suitcase A 1.25 seconds to reach its owner.

Answer:

In physics, the term "fluids" refers to substances that have no fixed shape and are capable of flowing. Fluids can be categorized into two main types: liquids and gases. Both liquids and gases are considered fluids because they can flow and take the shape of their container. Examples of liquids include water, oil, and blood, while examples of gases include air, helium, and carbon dioxide. The study of fluids is known as fluid mechanics and is an important field in physics and engineering.

Explanation:

Answer:

4 C

Explanation:

The strength of an electric field can be defined as: \(E = \frac{f}{q}\) where f=force and q=charge, and e=strength

Since we're given the strength and the force we can simply rearrange the equation so that we solve for Q:

Original Equation:

\(E=\frac{f}{q}\)

Multiply both sides by q

\(E*q = f\)

Divide both sides by E

\(q=\frac{f}{e}\)

So now plug the known values into the equation

\(q=\frac{1000 N}{250 N/C}\)

Simplify:

\(q = 4 c\)

The minimum velocity for the meteorite before entrance into earth's atmosphere is 36.8 m/s.

To calculate the minimum velocity the meteorite must have had before it entered Earth's atmosphere, the equation for heat transfer is:

Q = mcΔT

Where Q = the heat transferred,

m = the mass of the meteorite,

c = the specific heat capacity of iron, and

ΔT = the change in temperature.

The specific heat capacity of iron is approximately = 0.45 J/g°C.

Temperature of the meteorite changes from -105°C to the melting point of iron, which is approximately = 1535°C.

So: Q = mc(1535 - (-105))

Mass of the meteorite unknown, but we know it is made of iron, so assume a value for the mass, such as 100 g.

Q = 100 x 0.45(1535 - (-105))

Solving for Q:

Q = 67875 J

To calculate the kinetic energy of the meteorite, which is given by the equation: Ek = 1/2mv²

where Ek is kinetic energy,

m = the mass of the meteorite and

v = the velocity of the meteorite.

Therefore, the velocity of the meteorite is given by the following equation: v = √(2Ek/m)

Substituting the values of Ek and m, we get

v = √(2 x 67875/100)

Solving for v:

v = √1357.5

The minimum velocity the meteorite must have had before it entered Earth's atmosphere is approximately 36.8 m/s.

The density of the second liquid is 0.812 g/cm³

To calculate the density of the second liquid, we need to use the principle of displacement. The mass of the liquid can be found by subtracting the mass of the empty density bottle from the mass of the bottle filled with the liquid. Therefore, the mass of the liquid is:

mass of liquid = mass of bottle + liquid - mass of empty bottle

mass of liquid = 39.84g + x - 18.00g

where x is the mass of the liquid.

We can now use the density formula, which is:

density = mass/volume

The volume of the liquid is equal to the volume of the density bottle that is filled with the liquid, which can be calculated by subtracting the volume of the empty bottle from the volume of the bottle filled with the liquid. Therefore, the volume of the liquid is:

volume of liquid = volume of bottle filled with liquid - volume of empty bottle

We can now substitute this expression into the density formula to get:

density of liquid = mass of liquid / (volume of bottle filled with liquid - volume of empty bottle)

We know that the density of water is 1000 kg/m³, which is equal to 1 g/cm³. We can use this to find the volume of the liquid by dividing the mass of water by its density:

volume of water = mass of water / density of water

volume of water = 44.00g / 1 g/cm³

volume of water = 44.00 cm³

Now, we can calculate the volume of the density bottle filled with the second liquid by using the principle of displacement:

volume of bottle filled with liquid = volume of water - volume of liquid

volume of bottle filled with liquid = 44.00 cm³ - (39.84g - 18.00g) / 1 g/cm³

volume of bottle filled with liquid = 44.00 cm³ - 21.84 cm³

volume of bottle filled with liquid = 22.16 cm³

Finally, we can substitute these values into the density formula to get:

density of liquid = x / 22.16 cm³

Solving for x, we get:

x = density of liquid x 22.16 cm³

Substituting x back into the mass equation, we get:

mass of liquid = 39.84g + (density of liquid x 22.16 cm³) - 18.00g

Solving for the density of the liquid, we get:

density of liquid = (mass of liquid - 21.84g) / 22.16 cm³

Substituting the given values, we get:

density of liquid = (39.84g - 21.84g) / 22.16 cm³ = 0.812 g/cm³

In conclusion, the density of the second liquid is 0.812 g/cm³. This value is less than the density of water, which means that the second liquid is less dense than water and will float on top of water.

Answer:

the potential energy is zero, and the kinetic energy must be maximum

    F = 0

Explanation:

In this exercise you are asked to complete the sentences of a simple harmonic movement of a mass-spring system.

In this system mechanical energy is conserved

at the most extreme point the carousel potential energy is

          K_e = ½ k x²

the kinetic energy is zero for that stopped.

At the equilibrium point

the spring elongation is x = 0 so the potential energy is zero

and the kinetic energy must be maximum since total energy of the system is conserved

the spring force is

             F =- k x

as in the equilibrium position x = 0 this implies that the force is also zero

             F = 0

In this exercise we have to use the knowledge of force to calculate the energy of a spring, in this way we find that:

The potential energy in the spring is at its \(K_e = 1/2 k x^2\). The kinetic energy of the mass is at its zero . The magnitude of net force acting on the mass is at its Zero.

In this system mechanical energy is conserved,  at the most extreme point the carousel potential energy is:

       \(K_e = 1/2 k x^2\)

The kinetic energy is zero for that stopped or when at the equilibrium point, so:

the spring force is:

          \(F =- k x\\F=0\)
