Answer:
Option C
Explanation:
Kinetic energy is the energy that the body possesses by virtue of its motion.
The formula for Kinetic energy is given by
Using this formula let us find kinetic energy for the bodies given and find out which is the greatest
A) KE =
B) KE =
C) KE =
D) KE =
Comparing these we find that 9mv^2 is the highest.
Hence option C is the answer.
Answer:
3.52176 x 10^-10 N
Explanation:
Fg = 3.52176 x 10^-10 Newton
Answer:
Explanation:
The forces compare together as a result of the fact that the force exerted by that of the ball and the force exerted by that of the wall both have the same magnitude.
Answer:
Explanation:
Average speed is distance traveled over time taken to do so
home to station
d = 60 km
t = 60 km/60 km/hr = 1 hr
station to shop
d = 60 km
t = 60 km / 120 km/hr = ½ hr
speed
s = (60 + 60) / (1 + ½) = 120/1.5 = 80 km/h
Answer:
Waves transfer energy, not motion
