Explanation:

Did the practice

(1) The fighters wear padded gloves to protect their hands because there is an equal and opposite force impacting the hand.

(2) The two balls when collide in a closed system will exert equal and opposite force.

(3) When the mass of the object increases, the velocity of the object will decrease to conserve momentum.

(4) The equation for calculating the momentum of an object is P = mv

(5) The momentum of the ball is 100 kg.m/s

(6) The train cars move together in the direction the large car was moving.

(7) The conservation of momentum of two objects is [tex]m_1v_1 - m_2v_2= 0[/tex]

(8) The sum of two vectors can be found by  drawing the vectors perpendicular to each other.

(9) A closed system can be changed without changing the net force on the system by increase the mass and decrease the acceleration by the same numeric values.

(10) Acceleration is defined as the change in velocity over time.

(11) As ball rolls down at constant velocity, the ball has no net force acting on it.

(12) The conservation of momentum of the object is [tex]m_1v_1_i + m_2v_2_i = m_1v_1_f + m_2v_2_f[/tex]

(1)

According to Newton's third law of motion, action and reaction are equal and opposite.

The fighters wear padded gloves to protect their hands because there is an equal and opposite force impacting the hand.

(2)

Based on the principles of conservation of linear momentum, the two balls when collide in a closed system will exert equal and opposite force.

(3)

The principles of conservation of linear momentum is written as;

[tex]m_1u_1 + m_2u_2 = m_1v_1 + m_2v_2[/tex]

when the mass of the object increases, the velocity of the object will decrease to conserve momentum.

(4)

The equation for calculating the momentum of an object is written as;

P = mv

(5)

The momentum of the ball is calculated as follows;

P = mv

P = 50 x 2

P = 100 kg.m/s

(6)

For inelastic collision, the collided two objects move in the same direction after collision usually in the direction of heavier object.

The train cars move together in the direction the large car was moving.

(7)

The conservation of momentum of two objects is written as;

[tex]m_1v_1 = m_2v_2\\\\m_1v_1 - m_2v_2 = 0[/tex]

(8)

The sum of two vectors can be found by  drawing the vectors perpendicular to each other.

(9)

A closed system can be changed without changing the net force on the system by increase the mass and decrease the acceleration by the same numeric values.

(10)

Acceleration is defined as the change in velocity over time.

(11)

At constant velocity , acceleration = 0

∑F = ma

∑F = m x 0

∑F = 0

Thus, as ball rolls down at constant velocity, the ball has no net force acting on it.

(12)

The conservation of momentum of the object is written as;

[tex]m_1v_1_i + m_2v_2_i = m_1v_1_f + m_2v_2_f[/tex]

An object has a fixed volume and a variable shape before it changes state.
After the change, it can change in both shape and volume. Which change of
state has occurred? (APEX)
A. Gas to liquid
B. Solid to liquid
C. Liquid to gas
D. Gas to plasma

Answers

Answer:

A

Explanation:

The answer is C because the liquid has to turn into gas which the liquid has volume and a variable shape. Gas does not have volume or shape.

An object has a fixed volume and a variable shape before it changes state. After the change, it can change in both shape and volume then the change of state occurred was liquid to gas

What is the matter?

Anything which has mass and occupies spaces is known as matter ,mainly there are four states of matter solid liquid gases, and plasma.

These different states of matter have different characteristics according to which they vary their volume and shape.

Liquid has a fixed volume but it can change its shape to any form but gases can change their volume as well as shape, therefore the correct answer is C.

A 25 N force is applied to a 1.4 kg mass on level ground. If a 5 N frictional force is present between the surface and the object, what is the magnitude of the acceleration of this object?

Answers

Given parameters:

Force applied to the mass = 25N

Mass of the body = 1.4kg

Frictional force  = 5N

Unknown:

Acceleration of the object = ?

Solution:

The net force on the object;

     Fapplied - Frictional force = net force (m x a)

 m is the mass of the body

 a is the acceleration

Input the parameters and solve;

    25 - 5 = 1.4 x a

         1.4a  = 20

             a = [tex]\frac{20}{1.4}[/tex]   = 14.3m/s²

         

The magnitude of the acceleration of the object is 14.3m/s²

If the force acting on a cart doubles, what happens to the carts acceleration?

Answers

Answer:

If the force on a cart doubles, the acceleration of the cart doubles.

Explanation:

For this problem, we need to consider the following equation:

Force = Mass x Acceleration

We can reasonably assume that the cart will have constant mass in the given force system.  With this assumption we can say the following relationship:

Force is directly proportional to Acceleration within the system.

Given that our force on the cart is doubled, then our acceleration of the cart must also be doubled.  You can mathematically express this as follows:

F = MA

2F = M * 2A

Hence, if force doubles, the acceleration doubles.
