The doppler effect has red and blue shifts. A red shift means something is moving farther away, and a blue shift means it is moving closer. The universe has a red shift, and since a red shift means that it is moving farther away, this tells astronomers that the universe is still expanding.

Explanation:
it is correct because that is what
Answer: Input work is the work done on a machine as the input force acts through the input distance.Other ways it would be the work done on a body or system, that is, forces that are applied to the body or system. This is in contrast to output work which is a force that is applied by the body or system to something else.Output work is the work done by a machine as the output force acts through the output distance. The machine does to the object to increase the output distance.
Explanation:
Answer:
D The temperature, pressure and volume will all increase
Acceleration of gravity is proportional to 1/D² .
('D' is the distance from the Earth's center.)
We need (D / R)² = 9.8
('R' is the Earth's radius.)
D/R = √9.8 = 3.13
Distance from Earth's <u>center</u> = 3.13 R
Distance above Earth's <u>surface</u> = 2.13 R = about 13,570 km =====================================================
<span>Accelerarea de gravitate este proporțională cu 1 / D².

D / R = √9.8 = 3,13
Distanța de la <u>centrul</u> Pamantului = 3,13 R
