Consider a system of a cliff diver and the earth. the gravitational potential energy of the system decreases by 28,000 j as the
olga2289 [7]

The decrease in gravitational potential energy of the system is given by

\Delta U = (mg) \Delta h

where

m is the mass, g is the gravitational acceleration, and \Delta h is the variation of height of the system.


(mg) also corresponds to the weight of the diver, therefore if we rearrange the equation and we use \Delta U=28000 J and \Delta h=32.0 m, we can find her weight:

mg=\frac{\Delta U}{\Delta h}=\frac{28000 J}{32 m}=875 N

Camera flashes charge a capacitor to high voltage by switching the current through an inductor on and off rapidly. In what time
Ber [7]

Answer:

The value is  \Delta  t = 4.0 *10^{-7} \  s

Explanation:

From the question we are told that

  The current is \Delta  I  = 0.100 \  A

  The  inductor  is L  =  2.0mH  =  2.0*10^{-3} \  H

  The voltage induced is  \epsilon   =  500 V

Generally the emf induced is mathematically represented as

      \epsilon =  L  *  \frac{\Delta I }{\Delta  t }

Here  \Delta  t is the time taken  

=>  \Delta  t =  \frac{L  * \Delta  I }{\epsilon }

=>  \Delta  t =  \frac{2*10^{-3}  * 0.100 }{500  }

=>  \Delta  t = 4.0 *10^{-7} \  s
