Awheeled cart is free to move along the x-axis. the cart has a mass of 4.00 kg and an initial velocity of 4.00 m/s in the +xdirection when it is at x = 0 m. if the cart is between x = –1 m and x = +2 m, the net force is 1.00 n in the positive xdirection. if the cart is between x = +2 m and x = +7 m, the net force is 4.00 n in the negative x-direction. if the cart is between x = +7 m and x = +8 m, the net force is 2.00 n in the positive x-direction. the net force is zero at all other locations.

it becomes positively charged by charging it

the force on the thing and the distance the force moves the thing

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
