The rms potential difference is defined as the peak value of the potential difference divided by the square root of 2:
where
is the peak value of the voltage (the maximum voltage).
The generator in our problem has a maximum voltage of
, so its rms potential difference is
Groups of cells make tissues.
Groups of tissues make organs.
Groups of organs make organisms.
Groups of organisms make communities.
The BOLD sentence above is your answer.
You can increase the turns of the coil and flow. The strength can be varied.
We are given the gravitational potential energy and the height of the ball and is asked in the problem to determine the mass of the ball. the formula to be followed is PE = mgh where g is the gravitational acceleration equal to 9.81 m/s^2. substituting, 58.8 J = m*9.8 m/s^2 * 30 m; m = 0.2 kg.
