What is the relationship between the lenght of a pendulum and its period (e.g. how wil the period of the pendulum change-proportionality- if you change the lenght from .1m to .2m)

What is the relationship between mass and period...if any

What is the relationship between the angle of release for the pendulum and the period

I would really appreciate if you could help me in anu of these

Doing a project and wanted to know does an object's measurement, whether it be diameter or length, increase or decrease when you look at it under a magnifying glass and measure it there and compare it to the actual measurement?

". . .such as bacteria, have a complexity of about 10 million bits"

My question is strange, I don't know how else I could put it at the moment. How does one measure complexity in bits, or convert complexity to bits?

If there is an apple sitting on a table, what are the forces acting on it? I know that there is gravity pushing in a downwards direction. I also know that there is a second force pushing up on it. Would that be the table exerting a force on the apple in an upwards direction?

So arent the forces inside the atom basically fictious because the cause of attraction between the micromasses is really spacetime curvature and warping?

A spring with a spring constant of 2.4 N/cm is compressed 20 cm and released. The 8 kg mass skids down the frictional incline of height 27cm and inclined at a 19 degree angle. The acceleration of gravity is 9.8 m/s2.

The path is frictionless except for a distance of 0.6m along the incline which has a coefficient of friction of 0.5.

What is the final velocity of the mass ? Answer in units of m/s

A pinball machine launches a 125 g ball with a spring-driven plunger. The game board is inclined at 7 degrees above the horizontal. Assume the plungers mass and frictional effects are negligible. The acceleration of gravity is 9.8 m/s2.

Find the force constant k of the spring that will give the ball a speed of 93 cm/s when the spring compressed 2 cm from its relaxed position. Answer in units of N/m

Two radio antennas 60m apart broadcast a synchronized signal with a frequency of 100Hz. Imagine that we have a detector 5.0km away from the antennas. At this distance, what is the separation between adjacent bright spots in the interference pattern along a line parallel to the line between the antennas? I need a detailed explanation.

A mass of 1kg is on a frictionless table connected to a string over a pulley to a .5kg mass suspended over the edge of a table. What is the acceleration of each mass??

At first, I got 9.8m/s^2 for both of them...but it seemed wrong. Any ideas?
