In what ratio the mass 4m should be split so the value of gravitational force comes maximum for a fix distance d between the masses?
f=g(4m-x)/r^2 g/r^2(4m-x^2)

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

A51 kg woman skis down a hill and her kinetic energy is 9.96e4 j. what is her speed?

The first law of thermodynamics is as follows: ∆u=q-w , which means in a system is equal to added, minus done by the system. the units for these variables are in .
