Answer: 1.0
Explanation:
not sure why but that is the correct answer
Answer:
U = 1000 J
Explanation:
By the conservation of energy, potential energy is converted into kinetic energy when the ball falls from a height.
U = Energy (in Joules)
m = mass (in kg)
v = velocity in (m/s)
g = acceleration due to gravity (in m/s^2)
h = height (in m)
Let's use as we have the values given.
Answer:50 miles per hour 50/1hr
Explanation:100 divided by 2 is 50, divide 2 by 2 thats 1
Answer:
those who are attracted to magnets. ex: iron, cobalt and nickel
Answer:
100 W
Explanation:
The power can be defined as energy change / time taken
Or
Energy used/time taken
So in this case you get,
Power = 2500/25 = 100 W
