7 Mr. Robbins is taking his baby for a walk in a stroller. The amount of force that Mr. Robbins must use
to make the stroller move MOST likely depends on the stroller's -
A direction
B
distance
C velocity
D
mass

How is the gravitational force related to the distance between two objects?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j
