Two carts with masses Of 400g and 200g move towards cach other in the same straight line. At some point the carts collide. If the force exerted by the large cart on the small one is 4N calculate the force exerted by the small cart in the big. (sorry to bother if anyone could help it would be so appreciated)

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

i will answer your question if you answer mine

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
