Problem: A weather balloon is filled with helium and has a mass of 5.00 kg and radius 2.879 m. Instruments are added with a mass of 10.0 kg.
Part A: Calculate the net acceleration of the balloon and answer if the balloon will rise with that weight.
I want help to find the net acceleration of the balloon.
Suppose a patient having an MRI is immersed in a 3.0 T field along the axis of his body. He then quickly tips his head to the side, toward his right shoulder, tipping his head by 30 degrees in the rather short time of 0.15 s.
If you place the box on a dolly of mass 4.7 and with coefficient of rolling friction 2.0×10−2, illustrate what horizontal acceleration would that 154 force provide?
An electron in a multi electron atom has = +3. For this electron, what are the (a) smallest possible value of, (b) the smallest possible value of n, and (c) the number of possible values of ms?
