The answer is false because the laser doest burn the images onto the paper.
The work done by the force in pulling the block all the way to the top of the ramp is 3.486 kJ.
<h3>What is work done?</h3>
Work done is equal to product of force applied and distance moved.
Work = Force x Distance
Given is a block with a weight of 620 N is pulled up at a constant speed on a very smooth ramp by a constant force. The angle of the ramp with respect to the horizontal is θ = 23.5° and the length of the ramp is l = 14.1 m.
From the Newton's law of motion,
ma =F-mg sinθ =0
So, the force F = mg sinθ
Plug the values, we get
F = 620N x sin 23.5°
F = 247.224 N
Work done by motor is W= F x d
The force is equal to the weight F = mg
So, W = 247.224 x 14.1
W = 3.486 kJ
Thus, the work done by the force in pulling the block all the way to the top of the ramp is 3.486 kJ.

Yes. Amen. Tell me about it.
Answer:D 780,000,000km
Explanation:
1 AU is the distance of the sun to the earth and this value is 150,000,000km
Jupiter's distance from the sun is 5.2AU and is equivalent in km is:
5.2AU × 150,000,000Km= 780,000,000km
Answer:
the answer is 0 .75m
Explanation:
where are finding the distance the speed is given as well as the time..so you multiple the speed with the time thus you get the distance..i hope that's the answer..
