Which statement BEST explains an aspect of the differential heating of Earth's surface by the Sun? A. Liquids and solids absorb and store heat differently.
.
B. Photons interact differently with solids and liquids.
C. The atmosphere over the ocean is different than the atmosphere over
land
O D. Photosynthesis in the oceans uses more solar energy than
photosynthesis on land.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

it is called kinetic energy

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

lol
