It is always good to have an understanding of the magnitude of physical units. in physics, pressure is typically measured in units of pascals (pa). categorize each object according to the pressure it exerts when placed on a flat surface. assume that the bottom of each object is flat.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

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.

answera compound;

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
