Answer:

R= 5.4 ohms

Explanation:

Given that

V= 9 V

Power ,P= 15 W

Lets take resistor resistance = R

We know that Power given as

$P=\dfrac{V^2}{R}$

V=Voltage

P=Power

R=Resistance

$R=\dfrac{V^2}{P}$

Now by putting the all the values in the above equation

$R=\dfrac{9^2}{15}$

R= 5.4 ohms

Therefore the resistance of the resister will be 5.4 ohms.

The same book is placed on a table .9m high. What type of energy does it have and how much?

Lina20 [59]

mass (m)= 5 kg

height (h)= 9m

gravity (g)= 9.8 m/s^2

It has Potential energy. (PE)

• PE = mgh

Replacing:

PE = 5 * 9.8 * 9 = 441 Joules
