Answer: Because of the reflects back into space equal amount of radiation as it receives.

Explanation: The Earth's temperature doesn't keep rising because as the Earth receives the radiation from the sun, the Earth reflects back an equal amount of that radiation back to space.

This reflective ability of a planet of the sun radiation incident on it is known as the albedo.

A climber pulls down on a rope causing his body to rise up with the rope? Which law of motion is it?
12345 [234]
This would be called the law of action-reaction. This states that every action will have an equal and opposite reaction. The action in the example is pulling down on the rope. The opposite and equal reaction is the climers body moving upward. The same law can be applied to a rocket. The action is the engines pushing down and the reaction is the rocket going up. :D

(b) If the object is at 330 feet and its instantaneous velocity is 3 feet per minute at 30 minutes, what is the approximate posi
ELEN [110]

Answer:

The final position is 36 feet.

Explanation:

initial position, d = 330 feet

speed, v = 3 feet per minute

time, t = 30 minute

now the time is 32 minute

time interval = 2 minute

So, the distance in 2 minutes is

d' = 2 x 3 = 6 feet

So, the final position is

D = 30 + 6 = 36 feet
