<span>The nature of potential energy is that the zero point is arbitrary; it can be set like the origin of a coordinate system. That is not to say that it is insignificant; once the zero of potential energy is set, then every value of potential energy is measured with respect to that zero. Another way of saying it is that it is the change in potential energy which has physical significance.
Hope this Helps! </span>
The answer is A The waves filter ice from food
The equation that relates the voltages and the number of turns in a transformer is
where
is the voltage in the secondary coil,
is the voltage in the primary coil, and
and
are the number of turns on the secondary and primary coils.
Using the numbers, we find the ratio between the number of turns:
<h2>
Velocity at maximum height is zero.</h2><h2>Acceleration at maximum height is 9.81 m/s² downward.</h2><h2>Acceleration when it just hits the ground is 9.81 m/s² downward.</h2>
Explanation:
For a ball thrown vertically upward, the velocity at maximum height is zero.
Acceleration is a constant for a ball thrown vertically upward, its is acceleration due to gravity.
Acceleration at maximum height is 9.81 m/s² downward.
Acceleration when it just hits the ground is 9.81 m/s² downward.
