Answer:
A 2.0 kg ball, A, is moving with a velocity of 5.00 m/s due west. It collides with a stationary ball, B, also with a mass of 2.0 kg. After the collision
Explanation:
At -40.
-40 gives the same reading for Fahrenheit and Celsius scale.
Answer:
A - 0 N
plz mark 5 stars, thanks, and brainliest
The answer is the last choice.
Its electrical potential energy stays the same because it has the same electric potential. The reason why is that moving the charge towards X does not change the distance of the negative charge between the plates. The Electrical potential energy of a particle is the result energy by virtue of its position from the electrical fields produce by the plates both positive and negative. Since the charge is still equidistant to each other (assuming based from the diagram) no change in terms of electrical energy consumption or work was done.
Work:
1 kilometer = 1000 meters
45 × 60 = 2700
W = F × D
W = 2,000 N × 1,000 m
W = 2,000,000 J
P = W ÷ t
P = 2,000,000 J ÷ 2,700 s
P = 741 watts
Answer:
741 watts of horse power.
