Kristina does work to increase the gravitational potential energy. Kristina does work to increase the elastic potential energy.

Answers

Answer 1

Answer:

It's A

Elastic potential energy changes to gravitational potential energy

Explanation:

Answer 2

Step 4 can be described as "elastic potential energy changes to gravitational potential energy." The correct option is A.

What is the difference between potential energy and gravitational potential energy?

Potential energy is the energy stored in an object due to its position, configuration, or state. It is a scalar quantity that describes the amount of energy that an object possesses by virtue of its position or configuration.

Gravitational potential energy, on the other hand, is a specific type of potential energy that is associated with an object's position in a gravitational field. It is defined as the amount of work that must be done to move an object from its current position to a reference position where its gravitational potential energy is zero, typically at an infinite distance away from the gravitational source.

The gravitational potential energy of an object depends on its mass, its height above a reference level, and the strength of the gravitational field in which it is located. The formula for gravitational potential energy is:

PE_grav = mgh

Where PE_grav is the gravitational potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the reference level.

So, potential energy is a general term for any type of energy stored in an object, while gravitational potential energy is a specific type of potential energy that is associated with an object's position in a gravitational field.

Here in the Question,

When the toy is pushed down in Step 1, energy is stored in the spring as elastic potential energy. As the spring compresses in Step 2, this potential energy is increased.

When the toy is released in Step 3, the compressed spring rapidly expands and releases the stored elastic potential energy. This energy is then converted into kinetic energy as the toy jumps into the air.

As the toy jumps into the air, its height increases and it gains gravitational potential energy. This energy is due to the toy's position in a gravitational field, and it is stored in the toy's interaction with Earth's gravitational pull.

Therefore, the energy transformation that occurs in Step 4 is from elastic potential energy to gravitational potential energy.

"A farmer needs to get hay to cows in a frozen field. Using an airplane flying 40 m/s, at a height of 280 m, how far from the cow would she have to release the hay in order to hit the cow?" What is the horizontal velocity you would use to solve this problem?

Answers

Answer:

x = 302 m

Explanation:

Given that,

Speed of an airplane, v = 40 m/s

Height, h = 280 m

40 m/s is the horizontal velocity we should use to solve the given problem.

Let t is the time when the hay will reach the ground. It can be calculated using second equation of motion as follows :

[tex]h=ut+\dfrac{1}{2}at^2[/tex]

Here, u = 0 and a = g

[tex]h=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\times 280}{9.8}} \\\\=7.55\ s[/tex]

Let the horizontal distance is x. It can be calculated as :

x = vt

x = 40 m/s × (7.55 s)

x = 302 m

Hence, at a distance of 302 m she have to release the hay in order to hit the cow.

A car travels a distance of 3330 meters in 165 seconds what is the velocity

Answers

Answer:

Velocity = 20.18 m/s

Explanation:

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

[tex]Velocity = \frac{distance}{time}[/tex]

[tex]V = \frac{d}{t}[/tex]

Given the following data;

Distance, d = 3330m

Time, t = 165 secs

*To find the velocity*

Substituting into the equation, we have;

[tex]V = \frac{3330}{165}[/tex]

Velocity = 20.18 m/s

a car at point A travels at a constant velocity of 80km/h towards point B. the distance between the points is 160km. how long does it take to get from point A to point B

Answers

Answer:

t = 7200.07seconds or 2 hours

Explanation:

given:

velocity (v) : 80km/h = 80 × 1000 m/ 60 × 60 s

= 80,000m/3600s => 22.222m/s

distance(d) = 160km => 160 × 1000 = 160,000m

time(t) = ?

since v=d/t

therefore, t= d/v

t= 160,000/22.222

t= 7,200.07seconds

or t= 7,200/3600 = 2 hours.

Together with a friend, you are carrying a ladder that weighs 130 N. You have cleverly convinced your friend to hold the ladder 0.1 m from the center of gravity, while you yourself are 1.5 m from the center of gravity. How much of the weight of the ladder are you yourself supporting?

Answers

Answer:

W₁ = 8.12 N

Explanation:

Consider the weight supported by the person and friend to be:

W₁ = Weight supported by person

W₂ = Weight supported by Friend

Now, their sum must be equal to total weight of ladder. Hence,

W₁ + W₂ = 130 N

W₂ = 130 N - W₁   ---------------- equation (1)

Now, to carry the ladder, the moment due to both person's forces must be equal:

Moment due to person 1 = Moment due to friend

W₁ d₁ = W₂ d₂

where,

d₁ = distance between person and center of gravity = 1.5 m

d₂ =  distance between friend and center of gravity = 0.1 m

W₁(1.5 m) = W₂(0.1 m)

W₁ = W₂ (0.1 m/1.5 m)

W₁ = W₂(0.06667)

using equation (1):

W₁ = (130 N - W₁)(0.06667)

W₁ + 0.06667W₁ = 8.6667 N

W₁ = 8.12 N

A 0.25 kg Soccer ball is rolling at 6,0 m/s toward a player, The player kicks the ball in the opposite direction and gives it a Velocity of 24.0 m/s. A) What is the change in Momentum of the Ball? B) If the actual kick lasts ,02 selonds, what Force acts on the ball?

Answers

Answer:

A) ΔP = 4.5 [kg*m/s]

B) F = 375 [N]

Explanation:

The linear momentum is defined as the product of the mass of a body by Velocity, therefore we must calculate the momentum for each case.

[tex]P = m*v[/tex]

where:

P = linear momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

A)

When the soccer ball is rolling towards the player

[tex]P =0.25*6\\P = 1.5[kg*\frac{m}{s}][/tex]

After kicking the ball

[tex]P = 0.25*24\\P = 6 [kg*\frac{m}{s} ][/tex]

Therefore the change  momentum is equal to

ΔP = 6 - 1.5 = 4.5 [kg*m/s]

B) Momentum is defined as the force applied for a certain time, this momentum produces a linear momentum.

We must be especially careful in the directions of the movement, since depending on the direction a positive or negative sign must be included according to the established convention. In this particular case we are going to take the kick and the direction of this as positive, that is to say, the ball moves in the negative direction and after hitting the ball it moves in a positive direction.

[tex]-(m*v_{1}) + F*t = (m*v_{2})\\-(0.25*6) + (F*0.02) = (.25*24)\\F*0.02= (7.5)\\F = 375 [N][/tex]

a resistor, of resistance 47 , is damaged when it dissipates a power greater than 0.5W. determine the maximum voltage that can be applied without damaging the resistor​

Answers

Answer:

The maximum voltage that can be applied without damaging the resistor is 4.85 V

Explanation:

Electric Power in a Resistor

Given a resistor or resistance R connected to a circuit of voltage V carrying a current I. The relation between these three magnitudes is given by Ohm's Law:

V = R.I

The dissipated power P of a resistor can be calculated by the following equation, known as Joule's first law:

[tex]P = I^2.R[/tex]

Solving the first equation for I:

[tex]\displaystyle I=\frac{V}{R}[/tex]

Substituting in the second equation:

[tex]\displaystyle P=\frac{V^2}{R^2}.R[/tex]

Simplifying:

[tex]\displaystyle P=\frac{V^2}{R}[/tex]

Solving for V:

[tex]V=\sqrt{P.R}[/tex]

The resistor has a resistance of R=47Ω and can hold a maximum power of P=0.5 W, thus the maximum voltage is:

[tex]V=\sqrt{0.5\cdot 47}[/tex]

[tex]V=\sqrt{23.5}[/tex]

V = 4.85 V

The maximum voltage that can be applied without damaging the resistor is 4.85 V

(c) Applied force

(d) Friction force

(e) Tension force

(f) Air tension

Answer:

(b) Gravity force

(e) Tension force

(f) Air resistance

Explanation:

Normal force: NO, Normal force acts when body surfaces are in contact to push each other since lift is hanging and no surface contact is there so no Normal force.

Gravity force: YES. This force is acted on each and every body that lies in the vicinity of earth's gravitational field, as the life is hanging so it will experience Gravity force.

Applied force: NO.as there is no force given to the Elevator.

Friction force: NO. Friction fore occurs when bodies rub against each other or has a surface of contact, lift do not touch any surface hence no Frictional force.

Tension force: YES. The Elevator is hanging with the support of Four ropes and tension is acting in these ropes.

Air resistance: YES. The Elevator will experience Air resistance as it will move through the wide shaft.
