Answer:
b. Thermal energy will flow from your hand to the snowball.
Explanation:
Vi=12m/s Vf=16m/s t=8s a=? a=Vf-Vi/t=16-12/8=4/8=1/2 a=0.5m/s^2
Scientific form = 6.5 x 109.
The amplitude of wave-c is 1 meter.
The speed of all of the waves is (12meters/2sec)= 6 m/s.
The period of wave-a is 1/2 second.
The distance decreases as the time increases
