Answer:

There are three laws of newton

A 1.2 X 10⁻³ kg ball moving 4.0 collides head on and inelastically with a second 1.2 X 10⁻³ kg ball initially at rest. After colliding, the balls move together at the speed of 4.0 m/s.

To solve this problem, we can apply the principles of conservation of momentum and conservation of kinetic energy.

Given:

Mass of the first ball, m₁ = 1.2 x 10⁻³ kg

Mass of the second ball, m₂ = 1.2 x 10⁻³ kg

Initial velocity of the first ball, v₁ = 4.0 m/s

Initial velocity of the second ball, v₂ = 0 m/s

Since the collision is inelastic, the two balls stick together after the collision, moving as one object. Let's denote the final velocity of the combined balls as \(v_f_i_n_a_l\).

1) Conservation of momentum:

The total momentum before the collision is equal to the total momentum after the collision. Mathematically, it can be expressed as:

(m₁ * v₁) + (m₂ * v₂) = (m₁ + m₂) * \(v_f_i_n_a_l\)

Substituting the given values:

(1.2 x 10⁻³ kg * 4.0 m/s) + (1.2 x 10⁻³ kg * 0 m/s) = (1.2 x 10⁻³ kg + 1.2 x 10⁻³ kg) * \(v_f_i_n_a_l\)

(4.8 x 10⁻³ kg*m/s) = (2.4 x 10⁻³ kg) *\(\\v_f_i_n_a_l\)

2) Conservation of kinetic energy:

The total kinetic energy before the collision is equal to the total kinetic energy after the collision. Mathematically, it can be expressed as:

(1/2) * m₁ * v₁² + (1/2) * m₂ * v₂² = (1/2) * (m₁ + m₂) * \(v^2_f_i_n_a_l\)

Substituting the given values:

(1/2) * (1.2 x 10⁻³ kg) * (4.0 m/s)² + (1/2) * (1.2 x 10⁻³ kg) * (0 m/s)² = (1/2) * (1.2 x 10⁻³ kg + 1.2 x 10⁻³ kg) * \(v^2 _f_i_n_a_l\)

(4.8 x 10⁻⁶ kg*m²/s²) = (2.4 x 10⁻³ kg) * \(v^2_f_i_n_a_l\)

Dividing the first equation by the second equation, we get:

\(v_f_i_n_a_l/v^2_f_i_n_a_l\) = (4.8 x 10⁻³ kg m/s) / (4.8 x 10⁻⁶ kg m²/s²)

\(v_f_i_n_a_l=|v_f_i_n_a_l|\)

Since velocity is a scalar quantity, the final velocity of the combined balls must be a positive value.

Therefore, the final velocity of the combined balls is equal to the magnitude of the final velocity. In this case, the final velocity is positive and has the same magnitude as the initial velocity:

\(v_f_i_n_a_l=|v_f_i_n_a_l|\) = 4.0 m/s.

Hence, after the collision, the two balls move together at a speed of 4.0 m/s.

A. Good conductor of heat

Explanation:

The group 10 elements are a group of chemical elements as part of VIII elements and they include nickel, platinum, palladium etc. These group of chemical elements are all d-block transition metals, highly ductile and lustrous and are mostly white to light grey in color.

The statement which most likely describes a Group 10 element is that they are good conductor of heat because they have some of the chemical and physical properties of metals.

A force of 40. 0 n accelerates a 5. 0-kg block at 6. 0 m/s2 along a horizontal surface. The value of the net force acting on the block will be  79N.

The combination of mass and acceleration is known as force, and it acts on the body to cause it to move. Since the block is being affected by an external force, there will be a frictional force that prevents the block from moving. The frictional force is given by and can be represented by the symbol f(k).

f(k) = external force - (ma)

f(k) = 40N - (5×6)

f(k) = 40N - 30N

Since it opposes the external force, f(k) = 10N, and since the sign is negative, f(k) = -10N.

In addition, the body is subject to a gravitational force that is equal to mg, where g is the acceleration caused by gravity.

Now, force of gravity = mg

= 5×9.8 = 49N

Now, net force acting on the block = 40N - 10N + 49N= 79N.

Explanation:

Centripetal force is expressed according to the formula;

F = mv²/r

m is the mass of the body

v s the speed of the cart

r is the radius

Given

M = 2kg

r = 3m

Force F = 24N

Substitute into the formula and get v

24 = 2v²/3

24×3 = 2v²

v² = 72/2

v² = 36

v =√36

v = 6m/s

Hence the speed of the cart is 6m/s

The temperature change produced by a given amount of heat depends on the nature of the substance and its mass because different substances have different specific heat capacities.

The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of one gram of the substance by one degree Celsius.

Different substances have different specific heat capacities due to differences in their molecular structures and the way their atoms and molecules interact with each other. F

or example, water has a higher specific heat capacity than most other common substances, which means it takes more heat energy to raise the temperature of water than it does to raise the temperature of other substances by the same amount.

The mass of a substance also affects the temperature change produced by a given amount of heat. The more mass a substance has, the more heat energy it can absorb before its temperature changes significantly.

Answer: Inelastic: Elastic= 1:2

Explanation:

Among the four options listed here, time has the least impact on the potential energy or kinetic energy of an object. Thus, option 3 is the correct answer.

Potential energy is the energy an object has due to its position or state, and is dependent on the height of the object from the ground and its mass. Kinetic energy is the energy an object has due to its motion, and is dependent on its mass and speed.

While time is a factor that can affect an object's potential and kinetic energy, it is not directly related to these forms of energy. Time can affect the amount of potential energy an object has by allowing it to move to a higher or lower position, but it does not directly affect the energy itself. Similarly, time can affect the kinetic energy of an object by allowing it to move for a longer or shorter period, but it does not directly affect the energy itself.

Therefore, time has the least impact on the potential energy or kinetic energy of an object compared to mass, speed, and height from the ground.

The equilibrium temperature (T_final) of bodies A, B, and C will be equal to the initial temperature of body A (T_A).

To find the equilibrium temperature when bodies A, B, and C are put in contact, we can apply the principle of thermal equilibrium, which states that when two objects are in contact and there is no heat transfer to the surroundings, they will reach a common temperature.

Let's assume the initial temperatures of bodies A, B, and C are T_A, T_B, and T_C, respectively. Given the information provided:

Temperature of body B = 2 * Temperature of body A

Temperature of body C = 2 * Temperature of body A

Since all three bodies are in contact and made of the same material, they will eventually reach thermal equilibrium. This means that the final temperature (T_final) of the system will be the same for all three bodies.

To determine the equilibrium temperature, we can set up an equation based on the principle of thermal equilibrium:

(mass of A * specific heat of the material * change in temperature for A) + (mass of B * specific heat of the material * change in temperature for B) + (mass of C * specific heat of the material * change in temperature for C) = 0

Since the masses of A, B, and C are equal (ma = mb = mc), and they are made of the same material, we can simplify the equation to:

(ma * specific heat * (T_final - T_A)) + (mb * specific heat * (T_final - T_B)) + (mc * specific heat * (T_final - T_C)) = 0

Substituting the given information, we have:

(ma * specific heat * (T_final - T_A)) + (mb * specific heat * (T_final - 2 * T_A)) + (mc * specific heat * (T_final - 0.5 * T_A)) = 0

Simplifying further, we have:

ma * (T_final - T_A) + mb * (T_final - 2 * T_A) + mc * (T_final - 0.5 * T_A) = 0

Expanding and rearranging the equation:

T_final * (ma + mb + mc) - (ma + 2 * mb + 0.5 * mc) * T_A = 0

Since ma = mb = mc (equal masses), we have:

T_final * (3 * ma) - (3 * ma) * T_A = 0

Dividing both sides by 3 * ma:

T_final - T_A = 0

Therefore, the equilibrium temperature (T_final) of bodies A, B, and C will be equal to the initial temperature of body A (T_A).

In conclusion, the equilibrium temperature of the system will be the same as the initial temperature of body A.
