Power = (voltage) x (current)

If the camcorder is USING 14 watts of electrical power right now, then . . .

14 watts = (2 volts) x (current)

Divide each side by (2 volts):

Current = (14 watts) / (2 volts)

Current = (14 V-A) / (2 V)

<em>Current = 7 Amperes</em>

What is cathode ray tube?

The cathode ray tube determines the charge flowing in a gas. When an electric field is set up using metal electrodes, the cathode ray tends to bend towards the positive electrode.

This concludes that a charge and the electrodes present helps determine the charge of the beam of charged particle.

Thus, one of the main uses of this device is to test a beam of charged particles.

During the launch from a board, a diver's angular speed about her center of mass changes from zero to 8.10 rad/s in 240 ms. Her

Artemon [7]

Answer:

Part a)

$\alpha = 33.75 rad/s^2$

Part b)

$\tau = 391.5 Nm$

Explanation:

Part a)

Average angular acceleration is given as rate of change in angular speed

so it is given as

$\alpha = \frac{\omega_f - \omega_i}{\Delta t}$

$\alpha = \frac{8.10 - 0}{240\times 10^{-3}}$

$\alpha = 33.75 rad/s^2$

Part b)

average external torque is given as

$\tau = I\alpha$

here we know that

$I = 11.6 kg m^2$

$\tau = 11.6 \times 33.75$

$\tau = 391.5 Nm$
