Earth's temperature remains fairly steady, which means that earth must return the same amount of energy to space that it receives from the sun. in what forms does earth return most of this energy to space?
a) visible light reflected by clouds
b) ultraviolet light reflected by the surface
c) visible light reflected by the surfa

a, b and c

Explanation:

Earth return most of this energy to space in following forms

visible light reflected by clouds

ultraviolet light reflected by the surface

visible light reflected by the surface and atmosphere as well. \

Above all options are correct . Moreover, Earth's Albedo is  30% , meaning it reflects back 30% of the total incident radiation on the Earth. And the rest of the solar energy is absorbed or trapped by the phenomenon called Greenhouse effect.

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

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.
