Explanation:

The acceleration due to gravity on the surface of the asteroid is directly proportional to the mass of the asteroid and inversely proportional to the square of the distance from the center of the asteroid.

Therefore, it varies depending on the asteroid's size, shape, and composition.

Acceleration is the rate of change of velocity over time. A change in velocity, which can be either a change in magnitude or direction or both, results in acceleration.

It is measured in units of meters per second squared (m/s²) or centimeters per second squared (cm/s²).

Gravity is a fundamental force in physics that exists between any two objects in the universe.

The force of gravity pulls all objects with mass toward each other.

Gravity's strength depends on the mass of the two objects and the distance between them.

An asteroid is a small rocky or metallic object in space that orbits the sun. They are usually composed of rock, metal, or a combination of the two.

They vary in size from a few meters to hundreds of kilometers in diameter.

Most asteroids are found in the asteroid belt between Mars and Jupiter, although some are also found in other regions of the solar system.

Answer:

there is no list of "the following" you might want to re-upload your question.

It will take approximately 1.67 seconds for the car to go from a speed of 20.0 m/s to a speed of 25.0 m/s if the acceleration is 3.0 m/s².

\(v = u + at\)

Given:

u = 20.0 m/s (initial velocity)

v = 25.0 m/s (final velocity)

a = 3.0 m/s² (acceleration)

Rearranging the equation, we get:

\(t= \frac{(v - u)}{a}\)

Substituting the given values:

t =  \(\frac{(25.0 m/s - 20.0 m/s)}{3.0 m/s^{2} }\)

t = 1.67 s

Speed is the measure of the rate at which an object moves. It is defined as the distance an object travels per unit of time. Speed is a scalar quantity and is expressed in units of distance per unit of time, such as meters per second (m/s) or kilometers per hour (km/h). It is important to note that speed does not tell us anything about the direction of motion or any changes in direction. This is where velocity comes in, which is a vector quantity that includes both speed and direction.

Speed can be either average or instantaneous. Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed at a particular instant in time. Speed can also be described in terms of velocity, which includes direction as well as magnitude.

Explanation:

Let thermal capacity of the vessel be C' J K-1

Heat energy given by hot water = 40 x 4.2 x (60 - 30) = 5040 J

Heat energy taken by cold water = 50 x 4.2 x (30 - 20) = 2100 J

Heat energy taken by vessel = C' x (30 - 20) = 10 C' J

If there is no loss of heat energy,

Heat energy given by hot water = Heat energy taken by cold water and vessel

or 5040 = 2100 + 10 C'

or 10 C' = 2940

or C'= 294 J K-1

Thus, thermal capacity of vessel = 294 J K-1.

The skydivers are approximately 137.2 meters apart 8.0 seconds after the second skydiver jumps.

To determine the distance between the skydivers 8.0 seconds after the second skydiver jumps, we need to consider the vertical motion of the two skydivers.

Assuming no air resistance, both skydivers will experience free fall acceleration due to gravity, which is approximately 9.8 m/s^2.

Since the second skydiver jumps 2.0 seconds after the first skydiver, we can calculate their respective positions after 8.0 seconds using the equation of motion:

s = ut + (1/2)at^2

where s is the displacement, u is the initial velocity, a is the acceleration, and t is the time.

For the first skydiver:

Initial velocity (u) = 0 m/s (since the skydiver jumps from rest)

Acceleration (a) = 9.8 m/s^2

Time (t) = 8.0 s

Using the equation, we can calculate the displacement of the first skydiver after 8.0 seconds.

s1 = (0)(8.0) + (1/2)(9.8)(8.0)^2

s1 = 0 + (1/2)(9.8)(64)

s1 = 0 + 313.6

s1 ≈ 313.6 m

For the second skydiver:

Initial velocity (u) = 0 m/s

Acceleration (a) = 9.8 m/s^2

Time (t) = 6.0 s (since the second skydiver jumps 2.0 seconds after the first)

Calculating the displacement of the second skydiver after 8.0 seconds:

s2 = (0)(6.0) + (1/2)(9.8)(6.0)^2

s2 = 0 + (1/2)(9.8)(36)

s2 = 0 + 176.4

s2 ≈ 176.4 m

To find the distance between the skydivers, we subtract the displacement of the second skydiver from the displacement of the first skydiver:

Distance = s1 - s2

Distance ≈ 313.6 m - 176.4 m

Distance ≈ 137.2 m

Therefore, the skydivers are approximately 137.2 meters apart 8.0 seconds after the second skydiver jumps.

Answer:

Approximately \(176.58\; {\rm m}\) (assuming that \(g = 9.81\; {\rm m\cdot s^{-2}}\), both skydivers started with an initial velocity of zero, and that air resistance is negligible.)

Explanation:

Under the assumptions, each skydiver would be accelerating downward at \(a = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}\). The initial velocity of both skydivers would be \(u = 0\; {\rm m\cdot s^{-1}}\).

At \(t\) seconds after the second skydiver jumps, the first skydiver would have been in the sky for \((t + 2.0)\) seconds. Apply the SUVAT equation \(x = (1/2)\, a\, t^{2} + u\, t + x_{0}\) to model the position of each skydiver:

Subtract the two expressions to find the distance between the two skydivers:

\(\begin{aligned}& \frac{1}{2}\, a\, (t + 2.0)^{2} + u\, (t + 2.0) + x_{0} -\left(\frac{1}{2}\, a\, t^{2} + u\, t + x_{0}\right) \\ =\; & a\, (2.0)\, t + \frac{1}{2}\, a\, (2.0)^{2} + u\, (2.0) \end{aligned}\).

Substitute \(a = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}\), \(u = 0\; {\rm m\cdot s^{-1}}\), and \(t = 8.0\; {\rm s}\) into the expression and evaluate:

\(\begin{aligned}& a\, (2.0)\, t + \frac{1}{2}\, a\, (2.0)^{2} + u\, (2.0) \\ =\; & (-9.81)\, (2.0)\, (8.0) + \frac{1}{2}\, (-9.81)\, (2.0)^{2} + (0)\, (2.0) \\ \approx\; & -176.58\end{aligned}\).

In other words, the two skydivers would be approximately \(176.58\; {\rm m}\) apart.

Given the mass of whisky (m1) = 55g = 55x10^-3kg

Initial temperature of whisky (T1) = 22∘C

The final temperature of mixture = T

The mass of stone cube (m2) = 32g = 32x10^-3kg

The temperature of stone (T2) = -11∘C

The specific heat of stone is (Cs) = 980J/kg.K

The specific heat of whisky is (Cw) = 3400J/kg⋅K

Let the number of stones = 3

Following the combination, the stone cube gains hatred while the whisky loses heat.

Let the heat lost by whisky = Qw

Qw = 55 x 10^-3 x 3400J/kg⋅K x (22 - T)

Qw = 187(22 - T)

Let the heat gained by stones = Qs

Qs = 3 x 32 x 10^-3 x 980J/kg⋅K x (T-(-11))

Qs = 94.080(T+11)

We know that Qw = Qs such that

187(22 - T) = 94.080(T+11)

The charging by induction process is where the charged particle is held near an uncharged conductive material that is grounded on a neutrally charged material. The charge flows between two objects and the uncharged conductive material develop a charge with opposite polarity.

When an uncharged object is placed very close to a charged conductor without touching, the nearer end acquires a charge opposite to the charge on the charged conductors and the two bodies attract. This is called charging by induction. The net charge on the bodies remains the same and body is charged until they are kept close or brought in contact.

The speed of the spaceship as measured by the earth observer is 0.4c.

To determine the speed of the spaceship, we can use the time dilation formula:
Δt' = Δt/√(1-v²/c²)
where Δt is the time interval measured by the earth observer, Δt' is the time interval measured by an observer on the spaceship, v is the velocity of the spaceship, and c is the speed of light.
In this case, Δt' = 0.75 μs and the proper length of the spaceship, L, is 300 m.
Using the equation for proper length contraction, we can find L' = L/√(1-v²/c²)
Solving for v in both equations and equating them, we get:
v = (L/L') * c * √(1-((Δt/Δt')²))
Plugging in the values, we get v = 0.4c, where c is the speed of light. Therefore, the speed of the spaceship as measured by the earth observer is 0.4 times the speed of light.

Answer:

When a proton is placed directly in the path of the proton cannon, it will experience a strong electromagnetic force. The proton cannon emits a beam of protons at high energy and velocity. When the proton in the path of the cannon interacts with the beam, there will be a collision between the two protons.

During the collision, the protons may undergo a process called scattering, where they change direction and momentum. The exact outcome of the collision depends on the energy and angle of the incoming proton, as well as the properties of the target proton. It is possible that the protons may scatter off each other, transferring energy and momentum in the process.

In some cases, the collision may result in the absorption of the incoming proton by the target proton. This can lead to the formation of a more massive particle or the emission of other particles. The specifics of the interaction will depend on the energy and conditions of the proton cannon and the characteristics of the protons involved.

Overall, placing a proton directly in the path of a proton cannon will result in a collision and potential scattering or absorption of the protons, causing changes in their momentum and possibly leading to the creation of other particles.
