Answer:

Earth’s gravitational force is stronger

Explanation:

Earth’s gravitational force is stronger than the moon because of the presence of more massive objects in earth; on the flip side, the moon’s gravity is weaker than the earth due to smaller in size as compared to the earth. Earth gravity is denoted by g; conversely, moon gravity is denoted by gm

Answer: The greater an object's mass, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. That's why the moon isn't pulled out of Earth's orbit by the gravity of larger planets or by the sun.

Answer:

Weight

Explanation:

"An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object."

Answer:

a)  \(m_v= 56.16 Kg\)

    \(m_l= 14.04 Kg\)

b)  \(\mu=1.37\%\)

Explanation:

From the question we are told that:

Volume of tank \(V_t=1m^3\)

Temperature of \(CO_2=-17^oC\)

Quality of the mixture \(Q= 70%\)

Specific Volume constants at \(-17^oC:\)

 \(v_f = 0.9827*10^{-3} m3/kg\)

 \(v_g =1.756*10^{-2} m3/kg.\)

Generally the equation for Specific Volume is mathematically given by

 \(v = v_f + x (v_g -v_f)\)

 \(v= (0.9827 * 10^{-3} ) + 0.8 * (17.56 * 10^{-3} -0.9827 * 10^{-3})\)

 \(v= 0.014244 m3/Kg\)

Generally the equation for Mass is mathematically given by

 \(m=\frac{v'}{v}\)

 \(m=\frac{1}{0.014244}\)

 \(m=70.20 Kg\)

Generally the Mass of saturated Vapor is mathematically given by

 \(m_v=0.8 * (70.202)\)

 \(m_v= 56.16 Kg\)

Generally the Mass of saturated Liquid is mathematically given by

 \(m_l = (70.20 Kg)-(56.16 Kg)\)

 \(m_l= 14.04 Kg\)

b)

Generally the equation for Volume is mathematically given by

 \(v_l = m_l x v_f\)

 \(v_l= (14.04 Kg) (0.9827 x 10{-3} m3/kg)\)

 \(v_l= 0.01379 m^3\)

Therefore Percentage of liquid

 \(\mu = \frac{v_l}{v} * 100 \%\)

 \(\mu= [(0.01379 m^3)/(1 m^3)] *100 \%\)

 \(\mu=1.37\%\)

Kepler's laws are fundamental principles of celestial mechanics and continue to be valid for all planets in our solar system, including the ones discovered after Kepler's era.

Kepler's laws of planetary motion are fundamental principles that describe the motion of planets around the Sun and were derived based on observational data available to Johannes Kepler during the 16th and 17th centuries. However, these laws are not limited to the six planets known in Kepler's time.

Kepler formulated three laws of planetary motion:

1. Kepler's First Law (Law of Ellipses): Planets orbit the Sun in elliptical paths, with the Sun located at one of the two foci of the ellipse. This law applies to all planets, including those discovered after Kepler's time.

2. Kepler's Second Law (Law of Equal Areas): An imaginary line connecting a planet to the Sun sweeps out equal areas in equal time intervals. This law holds for all planets, regardless of when they were discovered.

3. Kepler's Third Law (Harmonic Law): The square of a planet's orbital period is proportional to the cube of its average distance from the Sun. This law applies to all planets, both the ones known in Kepler's time and the ones discovered later.

Kepler's laws are fundamental principles of celestial mechanics and continue to be valid for all planets in our solar system, including the ones discovered after Kepler's era. They provide important insights into the motion and behavior of celestial bodies.

The work required to stop the hoop is 600 joules and the distance traveled by the hoop on the inclined surface until it comes to the rest is 20.38 m.

(a) To stop the hoop, all of its kinetic energy needs to be converted into other forms of energy, such as heat due to friction. Therefore, the work required to stop the hoop is equal to its initial kinetic energy:

\(KE = 1/2 mv^2+1/2(mr^2)v^2/r^2\)

       \(= 1/2 (6.0\ kg)(10.0 \ m/s)^2+1/2(6.0\times1^2)\times 100/1\)

       \(= 600 J\)

Therefore, 600 J of work is required to stop the hoop.

(b) The initial kinetic energy of the hoop is the same as in part (a), so it is still 600 J. As the hoop rolls up the incline, some of its kinetic energy will be converted into potential energy, decreasing its speed. The work done by the force of gravity on the hoop as it rolls up the incline is equal to the change in potential energy, which is given by:

PE = mgh =600 J

\(h=600/(6\times9.81)\ m\)

\(h=10.19 \ m\)

Where h is the vertical height that the hoop rises.

Let the hoop rolls a distance of x m on the inclined surface.

\(x= h/sin30\)

\(x=10.19\times2=20.38\ m\)

Therefore the distance traveled on the inclined surface is 20.38 m.

Her mass is approximately equal to 27 kilograms.

First of all, you need to understand that momentum is a conserved quantity and the solution to this problem involves elastic collision.

Momentum can be defined as p = mv where p is momentum, m is mass, and v is velocity. Just like energy, momentum is a physical quantity that is conserved in an isolated system. Momentum is conserved as a result of Newton's third law, which states that \(F_A=-F_B\).

You are given that the ice skaters bounce off each other, meaning the collision is elastic. Remember that in an elastic collision, m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂ where

Suppose that m₁ = 49 kg, m₂ = x, u₁ and u₂ = 0 m/s, v₁ = 2.1 m/s, and v₂ = 3.81 m/s. Then the mass of the other ice skater is as follows:

49 · 0 + x · 0 = 49 · 2.1 + x · 3.81

0 = 102.9 + 3.81x

3.81x + 102.9 = 0

3.81x = -102.9

x ≈ -27

Since a mass value can't be negative, the absolute value of x is 27. Therefore, it's her actual mass in kilograms.

Doubling the diameter of the loop increases the area by a factor of four, which results in a four-fold decrease in the rate of change of magnetic flux and hence a four-fold decrease in the induced emf. In general, a loop is a closed path or circuit that goes from one point back to itself.

Doubling the diameter of a loop of wire produces a four-fold decrease in the induced emf, assuming all other factors remain constant. This is because the induced emf is directly proportional to the rate of change of magnetic flux through the loop, and the magnetic flux is proportional to the area of the loop. In mathematics, a loop is a fundamental concept in algebraic topology, where it refers to a path in a topological space that starts and ends at the same point. A loop can be used to define a group structure called a loop group, which has applications in mathematical physics and other areas.

Answer:

p = 0

Explanation:

Given that,

Mass of beetle, m = 750 kg

It was rest. It means its speed is equal to 0.

The momentum of an object is equal to the product of mass and velocity. So,

p = mv

p = 750 × 0

p = 0 kg-m/s

So, the momentum of the beetle is 0 kg-m/s.

The theoretical efficiency is greater than that of the actual efficiency of the engine. This is because heat engine always produces some waste heat.

The Second Law of Thermodynamics states that a heat engine cannot be 100% efficient. In practice, a heat engine is only 100% efficient when it is operating at about 30-50% efficiency.

If we were to multiply this by 100, we would get the efficiency as a percent: 49%. This is the theoretical maximum efficiency. If we were to actually build an engine, it would be less efficient than the theoretical engine. The theoretical engine that can achieve this theoretical maximum efficiency is called the Carnot Engine.

When the work done on the system is given by an external force. The total energy of the system increases by 2 × 10² J.

Given that,

200 joules of work is done on a system by an external force of 15 newtons in 20 seconds

The impulse on the system is nothing but the momentum of the system

That is,

F × t = m × V

15 × 20 = m × V

m × V = 300 N s

As energy = work done,

W = 1/2 m v² = 1/2 × 300 V

200 = 1/2 × 300 V

150 V = 200

V = 1.33 m/s

Now, let us calculate acceleration using an equation of motion.

V = u + a t

1.33 = 0 + 20 a

a = 0.067 m/s²

Now, let us calculate distance using the formula,

V² - u² = 2 a s

1.33² - 0 = 2 × 0.067 × s

0.134 s = 1.77

s = 13.21 m

So, the work done = F × s = 15 × 13.21 = 198.15 J ≈ 200 J

In physics, the concept of a frame of reference is used to specify the perspective from which an object or event is observed.

1). A frame of reference is where the measurements or observations will be made. Because of this, observing an event may be different when changing from one frame of reference to another, because the measurements will be different.

2). Defining frames of reference is necessary because the movement is relative, it may be that from our perspective or from a frame of reference on earth we are at rest, but seen from a frame of reference in space, we are in motion due that the earth is always moving.

3). Another example of frames of reference is a moving plane. Seen from the ground an object in the plane moves at the speed at which the plane travels, but if the frame of reference is fixed on the plane, the object is at rest.

The initial temperature of the water was approximately 81.67°C.

To solve this problem, we can apply the principle of energy conservation. The heat lost by the copper block is equal to the heat gained by the water.

The heat lost by the copper block can be calculated using the formula: Q1 = m1 * c1 * ΔT1,

where m1 is the mass of the copper block (40 g), c1 is the specific heat capacity of copper (0.39 J/g°C), and ΔT1 is the change in temperature (final temperature - initial temperature of the copper block).

The heat gained by the water can be calculated using the formula: Q2 = m2 * c2 * ΔT2, where m2 is the mass of the water (105 g), c2 is the specific heat capacity of water (4.18 J/g°C), and ΔT2 is the change in temperature (final temperature - initial temperature of the water).

Since the copper block and the water reach equilibrium, Q1 = Q2. Therefore, we can equate the two equations:

m1 * c1 * ΔT1 = m2 * c2 * ΔT2

Substituting the given values:

(40 g) * (0.39 J/g°C) * (95°C - initial temperature) = (105 g) * (4.18 J/g°C) * (24°C - initial temperature)

Simplifying the equation and solving for the initial temperature of the water gives us approximately 81.67°C.
