A driver exerts force on the foot brakes, causing the air pressure to change. The foundation brakes are applied and friction slows down the truck. How does decreasing the amount of time to compress the brakes and impact the power?

d) the number of neutrons plus the number of protons

multiply 2kg by latent heat of vap

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

it has to be b, about 97 percent.
