Which is the correct equation for the force applied by a spring?

Answers

Answer:

B. [tex]F = -k*x[/tex]

Explanation:

The force of a spring can be easily calculated using Hooke's law which tells us that the force applied on a spring is equal to the product of the constant of a spring by the compressed or stretched distance of the spring.

That is:

[tex]F = k*x[/tex]

k = spring constant [N/m]

x = distance [m]

Form hypothesis: How do you think increasing the resistance in a circuit will affect the current in the wire? (format: if, then, because)

Answers

Answer:it would make it thicker

Explanation:

Answer:

"The equation shows that the current in a circuit is inversely proportional to the resistance of the circuit. An increase in resistance would result in a decrease in current. And the factor by which the resistance increases is the same factor by which the current decreases."

Explanation:

Because it's just like wearing a glove/mitten when getting something out of the oven, because of the insulation from the glove/mitten, it reduces the heat that gets through into your hand, and it protects it. Just like what the "answer" says, it said that the resistance would decrease current.

Arif decided to make a model of the global wind patterns on Earth. He draws arrows of the global winds that move in a circular pattern from the equator to the poles and back again. Explain what causes global winds to form. Why do they move in convection currents around Earth? Please help

Answers

Answer:

The Earth's rotation which produces Coriolis force is the responsing factor for the formation and movement of different global winds.

The cause of the global winds is due to the rotation of the earth that produces the Coriolis force factor for the formation and movement of global winds.

What are global wind patterns?

The global wind pattern is formed by the movement of the earth and they are polar easterlies, prevailing westerlies and the trade winds.

Each of them occurs at about 30 degrees of latitude. Hence they form wind belts. The Coriolis effect that is created due to the rotation of the earth is a fact that leads to the movement of global winds.

Applying the Law of Conservation of Energy. If a car was released down the track from a height what happens to the potential energy and Kinetic energy as the car goes down the ramp?

Answers

Answer:

According to the law of conservation of energy, energy cannot be created or destroyed,  although it can be changed from one form to another.    KE + PE = constant. A simple example involves a stationary car at the top of a hill.  As the car coasts down the hill, it moves faster and so it’s kinetic energy increases and it’s potential energy decreases.  On the way back up the hill, the car converts kinetic energy to potential energy.  In the absence of friction, the car should end up at the same height as it started.

This law had to be combined with the law of conservation of mass when it was determined that mass can be inter-converted with energy.

One can also imagine the energy transformation in a pendulum.  When the ball is at the top of its swing, all of the pendulum’s energy is potential energy.   When the ball is at the bottom of its swing, all of the pendulum’s energy is kinetic energy.   The total energy of the ball stays the same but is continuously exchanged between kinetic and potential forms

A. One skater must remain at rest.
B. Nothing is known about the final total momentum.
C. The final total momentum must equal zero.
D. Since they are on ice, this will not work. Neither can move.

Answers

Answer:

A

Explanation:

Hopefully this helps

Two ice skaters are at rest and facing each other. In order to move, they push off each other, then their net final total momentum must equal zero, therefore the correct answer is option C.

What is momentum?

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

As given in the problem statement two ice skaters are at rest and facing each other. In order to move, they push off each other,  

By using the conservation of the momentum,

The initial total momentum of two skaters = the final total momentum of the skaters

Since, initially, they are at rest and their initial total momentum is zero  therefore the correct answer is option B

The Target employees are working hard to get the orders out to everyone. The employees need to move packages from the ground level to the top of the loading dock platform. As shown in Figure 1, the employee pushes the package up a ramp (you may assume friction is negligible). In figure 2, the employee lifts the package straight up from ground to the loading dock platform. In which case does the employee do more work on the box and why?

a
Lifting the box straight up, because the incline acts as a simple machine and reduces the force required
b
Lifting the box straight up, because it requires a larger applied force to lift it straight up
c
Pushing the box up the incline, because the force is applied for a longer distance

Which of these is an example of electrical energy being converted to mechanical energy?

Group of answer choices
Sunlight used by plants in photosynthesis
Ceiling fan
Lightning striking the ground

Answers

Answer:

Ceiling fan

Explanation:

A ceiling fan is an example of electrical energy being converted to mechanical energy.

The blades of the fan are driven by motor within the system.

Energy in a system is converted from one form to the other. Energy is neither created nor destroyed as we know from the law of conservation of energy. In this regard, the electrical energy from the outlet powers the motor. As the motor inside the fan spins, the blade in turn begins to rotate. The motion of the blade is the expression of mechanical energy.

The tree branch in the preceding problem sags, and the child's feet rest on the ground. If the tension in the rope is reduced to 220 N, what is the value of the normal force being exerted on the child's feet?

Answers

The complete question is

A 45-kg child sits on a 3.2-kg tire swing. The tension on the rope is 470 N. The tree branch sags and the child's feet rest on the ground. If the tension in the rope is reduced to 220 N, what is the value of the normal force being exerted on the child's feet?

Answer:

Therefore the Normal force is being exerted on the child's feet is 252.36( 250N).

Explanation:

We are given

mass of child = 45kg

mass of the tire = 3.2kg

g = 9.8 m/s^2

We have the first case in which the tire is in swing so tension in that case will be which is the resultant force.

Fr = Resultant force

Ft =  Tension force

Fg= Gravitational force

Fr = Fg + Ft

0 = -mg + Ft

Ft = mg

   = (45+3.2)*9.8

   = 48.2 * 9.8

Ft = 472.36N  ( which is close to 470)

In the second case the child is in the rest position, The resultant force will be zero.

Fr = Ft + Fn + Fg  ( Normal force is denoted by Fn )

0 = Ft + Fn + Fg

Fn =  -Fg -Ft

Fn = mg -Ft

    = 472.36 - 220

Fn  = 252.36N  ( close to 250N)

Therefore the Normal force being exerted on the child's feet will be 252.36N.  

Janet jumps horizontally off a high diving platform with a velocity of 2.76 m/s and lands in the water 2.3 s later. How high is the platform? The acceleration of gravity is 9.8 m/s. Answer in units of m.

How far from the base of the platform does she land? Answer and units of m.​

Answers

Answer:

(a) Let the height of the platform is h meter,

=>By s = ut + 1/2gt^2

=>h = 0 + 1/2 x 9.8 x (2.3)^2

=>h = 25.92 m

(b) By R = [Ux] x t

=>R = 2.47 x 2.3

=>R = 5.68 m

Explanation:

Explanation:

From the exercise we know the initial horizontal velocity and the time that Janet takes to land in the water

a) Knowing the formula for free falling objects, we can calculate how high is the platform

At t=2.3m the position of Janet is y=0m

So, the platform is 26m tall

b) According to dynamics the displacement of an object can be analyze using the following formula:

So, Janet lands 6 m far from the base of the platform

A sledge is pulled in a straight line by dogs, as shown. The dogs produce a total horizontal driving force of 600 N. The frictional force between the sledge and the surface is 150 N and the air resistance on the sledge is 450 N. What is the resultant force acting on the sledge

Answers

Answer:

F = 0 N

Explanation:

The direction of air resistance and frictional force will be same and opposite to the direction of the driving fore of dogs. Therefore, the resultant force can be given as follows:

[tex]resultant\ Force = F = Driving\ Force\ of\ Dogs - Frictional\ Force - Air\ Resistive\ Force[/tex]here,

driving force of dogs = 600 N

Frictional Force = 150 N

Resultant Force = 450 N

Therefore,

[tex]F = 600\ N - 150\ N- 450\ N[/tex]

F = 0 N

The acceleration due to gravity on the earths surface is?​

Answers

Acceleration due to gravity depends directly on the mass of Earth and inversely to the square of radius of Earth.

Answer:

9.8 m/s2

Explanation:

Acceleration due to gravity is the acceleration gained by an object due to the gravitational force. Its SI unit is m/s 2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.

A baseball on the Moon and an identical baseball on the Earth are thrown vertically upward with the same initial velocity of 12 m/s. The acceleration due to gravity on the Moon is 1/6 that of Earth. What is the maximum height the ball reaches on the moon? What is the maximum height the ball reaches on the earth? What is the difference in the maximum height the ball reaches on the Moon compared to on Earth?

Answers

Answer:

a. 3.68 m b. 0.61 m c. 3.07 m

Explanation:

a. What is the maximum height the ball reaches on the moon?

Using v² = u² - 2g'h where u = initial velocity of baseball = 12 m/s, v =  final velocity of baseball = 0 m/s (since it stops at maximum height), g' = acceleration due to gravity on moon = g/6 where g = acceleration due to gravity on earth = 9.8 m/s², so g' = 9.8 m/s²/6 = 1.63 m/s² and h = maximum height of ball on moon.

So, making h subject of the formula, we have

h = -(v² - u²)/2g'

substituting the values of the variables, we have

h = -((0 m/s)² - (12 m/s)²)/2(1.63 m/s²)

=  -(- 12 m²/s²)/2(1.63 m/s²)

= 6 m²/s²)/(1.63 m/s²)

= 3.68 m

b. What is the maximum height the ball reaches on the earth?

Using the same equation for the maximum height the baseball travels on the moon for that on the earth, the maximum height h' the baseball travels on the earth is given by  

h' = -(v² - u²)/2g where u = initial velocity of baseball = 12 m/s, v =  final velocity of baseball = 0 m/s (since it stops at maximum height),  g = acceleration due to gravity on earth = 9.8 m/s²and h' = maximum height of ball on moon.

substituting the values of the variables, we have

h = -((0 m/s)² - (12 m/s)²)/2(9.8 m/s²)

=  -(- 12 m²/s²)/2(9.8 m/s²)

= 6 m²/s²)/(9.8 m/s²)

= 0.61 m

c. What is the difference in the maximum height the ball reaches on the Moon compared to on Earth?

The difference in the maximum height the ball reaches on the Moon compared to on Earth is d = h - h' = 3.68 m - 0.61 m = 3.07 m
