Q4. A 5. 0-kg bowling ball rolls down a frictionless 2. 5 m tall ramp and strikes a stationary mass at the bottom of the ramp in a pertectly elastic collision.

To What

height back up the ramp does the first bowling travel after the collision if

a) the stationary mass is also 5. 0 kg

b) the stationary mass is 10. 0 kg

c) the stationary mass is 500. 00kg

the body's situation won't change the forces are equal opposit and on the same body

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

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
