Answer:
Weight is a force
Explanation:
Weight is the force of gravity on a mass. It can also be seen through this equation: F=ma, where m is the mass of the object and a is the acceleration of gravity.
Answer:
Explanation:
Length = 1.00 m
If the length is 1.0, the vertical distance pivot to bob is cos 35 = 0.819
At the lowest point, vertical distance is 1.0, so the change is the difference, 0.181 meter
The potential energy of that height is converted to kinetic energy of motion, which determines the speed.
PE = KE
mgh = ½mV²
V = √(2gh) = 1.88 m/s
Answer:
Most likely, it will be harder to get strong magnets to change phase because they have more density.
Answer:
Explanation:
The most common formula for average speed is distance traveled divided by time taken. The other formula, if you have the initial and final speed, add the two together, and divide by 2
A girl standing on a floor would have two opposite forces acting on it. These forces are the weight and the normal force. Since no other forces are acting and that the girl is at rest, then the weight must equate to the normal force. Therefore, the supporting force would be:
F = mg = 55kg (9.81 m/s^2) = 539.55 N
