Because if it is on Support Force this is the exert I was given by the book to help me answer this question. Consider a book lying at rest on a table. It is in equilibrium. What forces act on the book? One force is that due to gravity - the weight of the book. Since the book is in...

How exactly should I know this, I will check again but I don't think the book describes this at all. I would just like to know so I can get a little more practice and know what I am doing, instead of relying on the back of the book to confuse me. ** By any chance does it have to deal with...

1. Harry the painter swings year after year from his bosuns chair. His weight is 500 N and the rope unknown to him has a breaking point of 300 N. Why doesn't the rope break when he is supported as shown on the right ? One day Harry is painting near a flagpole and for a change, he ties the free...

1. Nellie Newton hangs at rest from the ends of the rope as shown. How does the reading on the scale compare with her weight? 2. ANSWER FROM BOOK. The scale will read half her weight. In this way, the net force (upward pull of left rope + upward pull of right rope rope weight = 0 3. Can...

I am making an assumption saying it is free to rotate, every single one I have encountered is. usually it tears because of the perforated edges. As well as I am assuming that the force and the jerk kind of the theory of the bus - when the bus accelerates you move forward and when it decelerates...

1. Suppose that you're in a moving car and the motor stops running. You step on the brakes and slow the car to half speed. If you release your foot from the brakes, will the car speed up a bit, or will it continue at half speed and slow due to friction? Defend your answer. Homework...

1. In tearing a paper towel or plastic bag from a roll, why is a sharp jerk more effective than a slow pull 2. I found this answer online A quick, sharp jerk means a greater acceleration and a greater acceleration means a greater force. And it is force that tears the paper towel or...

My question was my answer I thought, but I was thinking if someone was pushing the crate at 100 N and there was 100 N of resistance how would they be pushing it but you answered my thought they wouldn't be.

Okay I see, thank you!

If you push on a crate with a force of 100 N and it slides at constant velocity, how much is the friction acting on the crate? Consider a crate being pushed horizontally across a factory floor. If it moves at a steady speed in a straight - line path, it is in dynamic equilibrium. This tells...

awesome thank you

1. What is the net force on a cart that is pulled to the right with 100 pounds and to the left with 30 pounds? Changes in motion are produced by a force or combination of forces. A force, in the simplest sense is a push or a pull. Its source may be gravitational, electrical, magnetic, or...

like this statement I think is a perfect example of philosophy and physics. Russel wrote. " I think we must retain the belief that scientific knowledge is one of the glories of man. I will not maintain that knowledge can never do harm. I think such general propositions can almost always be...

The more I think about it the more awesome that is, that the moon could or could not be the cause of the tide. Which you are correct we can't remove the moon so how do we know. That is awesome! at least ancient philosophy wasn't the correlated with ancient science. Perhaps not modern day...
