Doc Al

can you please check my post :)

I have a question about calculating net torque.

Hello ,

I was inquiring about the electron velocity needed to ionize Oxygen molecule by collision ?

weight of earth is 6*10 power of 24 kgs,we are launching rockets,burning matter,so by this weight of earth must decrease,is it right or wrong?

can you tell me how to post a thread?

hi,i just joined the forum,i have a doubt can i ask you?

Hello, I just joined the forum and I cannot figure out how to post a question. I just see threads where I can respond to other to other questions and topices. All I want to know is if entropy in the universe was increased by twice the rate would the spin of the earth go at twice the speed having only 12.5 hour days? i

A mass m1 = 6.4 kg rests on a frictionless table. It is connected by a massless and frictionless pulley to a second mass m2 = 3.3 kg that hangs freely.
Now the table is tilted at an angle of θ = 75.0° with respect to the vertical. Find the magnitude of the new acceleration of block 1.

Thanks, have done this
