When a current I1=1.3 A passes through a wire of cross-sectional area A1=5 mm2the driftvelocity of the charge carriers is v1=2.7 ×10-5m/s. What is the drift velocity of the charges when acurrent I2=0.5 A passes through a wire, made of the same material of cross-sectional area A2=3mm2?

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.

where is the

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
