A Christmas sphere will break if dropped on hardwood floor with a velocity of 2.0 m/s. Mar Estefanla is decorating her Christmas tree when her cat, Missy, taps a sphere, causing it to fall 0.15 m from a tree branch to

the floor.

What is the velocity of the sphere right before it hits the ground? Acceleration due to gravity vs 9.8 m/s

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
