Consider two laboratory carts of different masses but identical kinetic energies and the three following statements. which of the statements below would be correct? a) the one with the greatest mass has the greatest momentum. b) the same impulse was required to accelerate each cart from rest. c) both can do the same amount of work as they come to a stop.

a) The one with the greatest mass has the greatest momentum.

c) Both can do the same amount of work as they come to a stop.

Explanation:

The relation between kinetic energy and momentum is shown below as:

Thus, having same kinetic energy, the greatest mass will correspond to greatest momentum.

Hence, Option a is correct.

Since, they have same kinetic energy, they can do the same amount of work when they come to stop as they posses same energy.

Hence, Option c is correct.

Since, Impulse is change in momentum. Thus, they both posses different momentum and thus, impulse will also not be same for both of them.

Hence, Option b is incorrect.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
