a. the change in mass of an object.
b. the change in volume of an object.
c. a force applied to an object for a period of time.
d. the original momentum of the object.

Answers

Answer 1

Answer:

c

Explanation:

impulse Is the product of force and distance so it's generally formula

Answer 2

The impulse should be equivalent to the option c.  a force applied to an object for a period of time.

What is an impulse?

Impulse of force represent the product of the resultant force ΣF and also the duration of the force Δt when the force should be constant. Also it should be lead to the changed to motion and changes to momentum

Therefore, The impulse should be equivalent to the option c.  a force applied to an object for a period of time.

The total mechanical energy of a system is 950 J and the gravitational potential energy is 350 J. What is the kinetic energy?​

Answers

Answer:

The kinetic energy is 600 J

Explanation:

Mechanical Energy

The principle of the conservation of mechanical energy states that the total mechanical energy in a system remains constant as long as the only forces acting are conservative forces.

The mechanical energy is defined as the sum of the potential plus kinetic energies:

E = U + K

Where E is the total mechanical energy, U is the gravitational potential energy and K is the kinetic energy.

Solving for K:

K = E - U

The system described has a total mechanical energy of E=950 J and gravitational potential energy of U=350 J, thus:

K = 950 J - 350 J

K = 600 J

The kinetic energy is 600 J

2. A driver of a car traveling at 15.0 m/s applies the brakes, causing a
uniform acceleration of -2.0 m/s". How long does it take the car to
accelerate to a final speed of 10.0 m/s?​

Answers

Answer:

2.5 s

Explanation:

The formula for acceleration is ;

a= v₂-v₁ / t

where ;

a= acceleration = -2 m/s²

v₂= final velocity = 10 m/s

v₁ = initial velocity = 15 m/s

t= time taken for the car to accelerate = ?

Applying the values in the formula as;

a= v₂-v₁ / t

-2 = 10 - 15 / t

-2t = -5

t= -5/ -2

t= 5/2 = 2.5 s

Susie Small finds she weighs 300 N.
Calculate her mass.

Answers

Answer:

30Kg

Explanation:

Weight = mass x gravitational field strength

300 = mass x 10

mass = 30kg

gravitational field strength is 9.8 on earth but normally we take it to be 10 for easy reference and calculations

The mass will be "30 kg". A further solution is provided below.

According to the question,

Weight,

300 N

We know that,

Gravitational field strength,

10

The mass will be:

→ [tex]Weight = Mass\times Gravitational \ field \ strength[/tex]

or,

→ [tex]Mass = \frac{Weight}{Gravitational \ field \ strength}[/tex]

By putting the values, we get

→           [tex]= \frac{300}{10}[/tex]    

→           [tex]= 30 \ kg[/tex]

Thus the above solution is right.

A skier rides horizontally off of a 200 meter high cliff. If he lands 25 meters away from the base of the cliff, how fast was he skiing as he went off the edge?

A. 0.91 m/s
B. 2.91 m/s
C. 3.91 m/s
D. 25.91 m/s

Answers

Answer:

the answers, the correct one is C,   v₀ₓ = vₓ = 3.91 m / s

Explanation:

This is a projectile launching exercise, in this case they indicate that when leaving the cliff it goes horizontally, therefore the initial vertical speed is zero, let's find the time to reach the base

        y = y₀ + [tex]v_{oy}[/tex] t - ½ g t²

at the base the height is zero (y = 0 m)

        0 = y₀ + 0 - ½ g t²

         t = √ (2y₀ / g)

         

we calculate

        t = √ (2 200 / 9.8)

        t = 6.389 s

with this time we calculate the horizontal speed

        v₀ₓ = x / t

        v₀ₓx = 25 / 6,389

        v₀ₓ = vₓ = 3.91 m / s

When checking the answers, the correct one is C

2. Two people, one on Earth and the other on the Moon, try and lift 200 kg blocks. Which person
will have to exert more force to lift their block or will they need to exert the same amount of
force? Explain your reasoning(4 pts)

Answers

Answer:

The person on Earth will have to exert more force to lift their block

Explanation:

The mass of the blocks to be lifted = 200 kg

The location of the first person = On Earth

The location of the second person = On the Moon

The force a person will have to exert to lift the block = The weight of the block = The gravitational force, F, on the block which is given as follows;

[tex]F = \dfrac{G \times M_1}{R^2} \times m_2[/tex]

Where;

[tex]\dfrac{G \times M_1}{R^2}[/tex]= The acceleration due to gravity on the Earth or the Moon, depending on the location of the block

m₂ = The mass of the block

Therefore, given that the acceleration due to gravity on the Earth is larger than the acceleration due to gravity on the Moon, the weight of the block on the Earth is larger than the weight of the block on the Moon, and the person on Earth have to exert more force to lift the heavier weight of the block on Earth than the person on the Moon will have to exert to lift the same block as the block has a lower weight on the Moon due to lower acceleration due to gravity on the Moon.

A cow standing atop a building in Times Square recalled a funny joke and began to laugh. The uncontrollable laughter caused the cow to fall over the side of the building. He fell for a time period of 3.5 s and landed in a bed of bushes. How fast was the cow moo-ving when he reached the bushes?

Which equation should be used to solve the problem?

Answers

Answer:

Vf = 34.3 m/s

1st equation of motion was used to solve.

Explanation:

In order to find the final speed of the cow, when it hits the bushes, we can use first equation of motion:

Vf = Vi + gt

where,

Vf = Final Velocity of Cow = ?

Vi = Initial Velocity of Cow = 0 m/s

g = acceleration due to gravity = 9.8 m/s²

t = time taken = 3.5 s

Therefore,

Vf = 0 m/s + (9.8 m/s²)(3.5 s)

Vf = 34.3 m/s

1st equation of motion was used to solve.

Which statement correctly describes the charge of the nucleus and the charge of the electron cloud of an atom?

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of options. However, the charge of a nucleus was discovered by Ernest Rutherford. The nucleus is located in the centre of an atom and it contains protons and neutrons. The protons are positively charged while the neutrons have no charge, thus the charge of the nucleus is positive because the neutrality of the neutron does not affect the charge of the proton.

The charge of an electron was first measured by Robert Millikan. Electrons are negatively charged subatomic particles that balance out the positive charge of the protons.

True. The force of the car on the bug will be equal to the force of the bug on the car.

Newton's third law

This statement is true according to Newton's third law of motion.

According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction.

In this case, the action is the force of the car on the bug, and the reaction is the force of the bug on the car.

Therefore, the force of the car on the bug is equal in magnitude and opposite in direction to the force of the bug on the car.
