Answer:
"Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material.
Explanation:
It helps applying force in any direction. Pulley systems rely on the relationship between the load and the effort. It also increase the lifting distance. Useful for getting the drive action to happen in awkward places. The bigger the mechanical advantage the lesser amount of force is needed to be exerted.
Answer:
Explanation:
What is a free body diagram?
Answer: a force diagram is a graphical illustration used to visualize the applied forces and resulting reactions on a body in a given condition
Drawing a free-body diagram for this problem
Answer: Look at the attached picture, ask me any questions if you are still confused. It is a little messy since I didn't have my pen.
Find its weight on Earth
Answer: The weight is dependent on the mass of the object and the gravitational constant on the planet. The gravitational constant, in this case, is 9.8.
so the weight = mass * gravitational constant = m * g = 1000 * 9.8
= 9800 N
Hope that helps!
The dog walked 5 meters backwards in the first 10 seconds, then 5 meters forward from 10-20 seconds. After 20 sec he was back where he started. Displacement (20sec) = zero.
