An object that is dropped has the most kinetic energy...


A. It does not have kinetic energy


B. When it starts to fall


C. Resting on the shelf


D. Just before it hits the ground

Answers

Answer 1

Answer:

B.

Explanation:

Kinetic energy is when an object has the power to move, Potential energy would be when its resting on the shelf.

Answer 2
B. When it falls because kinetic energy is when an object or person is in movement and potential is when a object or person stay still.

Suppose the two thermometers on a sling psychrometer show almost identical readings. Was the psychrometer more likely used on a Florida beach or in an Arizona desert? Explain your answer.

Answers

Remember that the two temperatures will be most different if evaporation is taking place rapidly, as this process absorbs heat faster than if little evaporation is taking place. In which location would you expect this to happen?

The psychrometer was used on a Florida beach.

A sling psychrometer is a measuring instrument that is made up two thermometers:

wet bulb thermometer andDry bulb thermometer.

The primary use of this thermometer is to measure the relative humidity of an area.

The Florida beach is high relative humidity because of the presence of the beach while the Arizona desert is low in relative humidity because water is rarely found in a desert.

Relative humidity is the amount or quantity of water vapor in the air.

To determine the relative humidity of an area, the reading in the both thermometers on the sling psychrometer is read and compared.

If the reading of the two thermometers on the sling psychrometer shows almost an identical reading then then the relative humidity of that area is high.

If there is a great difference between the two readings then the relative humidity of the area is low.

Therefore, the psychrometer was more likely used on the Florida beach.

I think being self disciplined is when you are a responsible and mature person and maybe raised yourself I don’t know what else to write you can expand on this
I think being self disciplined means you know right from wrong. You don’t need other people always telling you what is right and what you do wrong because you should know it yourself. I think this means you’re also well behaved and you know when to stop doing something if it pushes someone to the edge. Two habits I would associate with being self disciplined would be to make up your bed every morning or if someone says to stop doing something, you stop.

One of your friends read online that a city near a fault has experienced an earthquake every 10 years. The last earthquake in this city happened 10 years ago so your friend says that another one will happen this year. Is your friend correct? Why or why not?

Correct answer gets brainly,

Answers

Answer

your friend is correct.

Explanation

If the fault has experienced an earthquake every 10 years and that the last one was 10 years ago then this year would be the year it goes off again.

Your friend is correct because the last earthquake happened 10 years ago which means another one would happen that year...... if that makes sense

4. A child is riding their bicycle down the street to the left. Diagram the forces acting on the bicycle
PLS HELP ME AND DONT GIVE WRONG ANSWER...

Answers

Answer:

Friction is a big part of this. Rolling friction is acting on the bottom of the tires, and this causes the bicycle to keep rolling and not tip over. drag is the force that's pushing forwards opposite the bicycle, and gravity is the force keeping the bicycle on the ground.

friction is a very big part of this. since the child is riding down the hill than he/she will pick up movement

Greg and Karissa are about to start racing on their skateboards. Greg pushes off of the ground with 40 newtons of force. Karissa pushes off of the ground with 80 newtons of force. Greg and Karissa have the same mass.

How will Greg's acceleration compare with Karissa's acceleration?

Answers

Answer:

Greg's acceleration will decreace faster than Karissa will.

Explanation:

If Greg pushed off with less force and Karissa pushes off with more and they weigh the same Greg slows down before Karissa does. I hope this helped. :)

Karissa's acceleration is  is greater than Greg's acceleration.

What is force?

The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

A spring balance can be used to calculate the Force. The Newton is the SI unit of force.

Let the mass of Greg and Karissa is m.

Force applied by Greg = 40 Newton.

Force applied by Karissa = 80 Newton.

From Newton's second law of motion, we know that:

Force = mass × acceleration

Acceleration = force/mass

Hence, Greg's acceleration is = 40/m m/s²

Karissa's acceleration is = 80/m m/s²

As 80 > 40; 80/m > 40/m

So,  Karissa's acceleration is  is greater than Greg's acceleration.
