A, and D are two correct answers im not sure about the third sorry
Astronomers believe the sun like other stars was formed within a nebula
Answer:
The net effect on the laboratory is cooling of the space.
Explanation:
Given:
power used by the air conditioner,
coefficient of performance,
We know that:
<u>Therefore the cooling power capacity:</u>
The net effect on the laboratory is cooling of the space.
For a lightbulb, you turn electrical energy into heat and light energy. For a battery, you turn chemical energy into electrical energy and light energy? I could only go that far. Sorry :(
Answer:
3924 N
5124 N
4004 N
2884 N
4004 N
Explanation:
m = Mass of elevator = 400 kg
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration
f = Friction force = 80 N
When the elevator is stationary only the acceleration due to gravity will be acting on it
Tension
The tension is 3924 N
The balanced force equation would be
The tension is 5124 N
When velocity is constant acceleration is zero
The tension is 4004 N
The tension would be 2884 N
When velocity is constant acceleration is zero
The tension is 4004 N
