The acceleration is 3 m/s per minute, or 0.05 m/s per second.
Answer:
Almost all machines require energy to offset the effects of gravity, friction, and air/wind resistance. Thus, no machine can continually operate at 100 percent efficiency.
Answer: Try C
Explanation:
It's the only one that makes since.
(a) 
The change in energy of the transferred charge is given by:

where
q is the charge transferred
is the potential difference between the ground and the clouds
Here we have


So the change in energy is

(b) 7921 m/s
If the energy released is used to accelerate the car from rest, than its final kinetic energy would be

where
m = 950 kg is the mass of the car
v is the final speed of the car
Here the energy given to the car is

Therefore by re-arranging the equation, we find the final speed of the car:

Answer:
The correct answer should be high amplitude : )
Explanation:
A high energy wave is characterized by a high amplitude, a low energy wave is characterized by a low amplitud
