Answer 1

Answer #1

A) By Newtons law of Gravitation,

F = Gm1m2/r^2

= 6.67e-11*0.25*0.25/r^2

= 4.17*10^-12/r^2

Here r is distance between the masses whoch would have been given in the experiment.

Here F is so small with any r, that we can ignore them.

So the only significant forces will be Tension and weight mg.

Weight mg =0.25*9.8 = 2.45N acts downwards always.

A sign with a mass of 1 kg is hung by two ropes and hangs in equilibrium. Rope 1 (on the right in the sketch) is at an angle of 28 degrees from the horizontal. Rope 2 is hung vertically, goes through the ceiling, and by pulleys, is also connected horizontally to the side of the sign. In addition, a force of 22 Newtons is applied vertically downwards to the sign. What is the tension in rope 2 in Newtons?

A block with mass m =7.5 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.27 m. While at this equilibrium position, the mass is then given an initial push downward at v = 4.2 m/s. The block oscillates on the spring without friction. 3) After t = 0.32 s what is the speed of the block? 5) At t = 0.32 s what is the magnitude of the net force...
