A copper wire has a circular cross section with a radius of 1.00 mm. (a) If the wire carries a current of 2.80 A, find the drift
speed of the electrons in the wire. (Assume the density of charge carriers (electrons) in a copper wire is n = 8.46 1028 electrons/m3.) 2.1e-6 Incorrect: Your answer is incorrect. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s (b) All other things being equal, what happens to the drift speed in wires made of metal having a larger number of conduction electrons per atom than copper? Explain

To compute for the heat, 
needed to be absorbed or released, we need
where
is the mass of the alligator, 
is the change in temperature, and 
is the specific heat of the alligator's body. Plugging in all the information we have,
Recall that 1 Watt = 1 J/s, thus time needed to absorb radiation from the sun is
That means it takes 4250 seconds for the alligator to warm up to be able to absorb the radiation from the sun.
Answer: 4250 seconds

Answer: 4250 seconds
Answer:Decreases
Explanation:
Given
Volume is held constant that is it is a isochoric process.
We know that
PV=nRT
as n,V& R are constant therefore only variables are
P & T
so
As is decreasing therefore Pressure must also decrease so that ratio remains constant.
