3. What is the potential energy of a 8 Newton book sitting on a shelf that is 12 meters high?

Svetradugi [14.3K]

Answer:

P = 96 J

Explanation:

Given that,

Weight of the book, W = mg = 8 N

It is placed at a height of 12 m

We need to find the potential energy of the book. The potential energy of an object is given by the formula as follows :

E = mgh

mg = Weight

$E=8\ N\times 12\ m\\E=96\ J$

So, the potential energy of the book is 96 J.

How long does it took for 1000-watt microwave oven to do 20000 joules of work

svp [43]

Answer:

20 seconds

Explanation:

The equation for Power is:

$Power = \frac{Work}{time}$

Which means...

$Time=\frac{Work}{Power}$

We can plug in the given values into the equation:

$Time = \frac{20000\ J}{1000\ W}$

$Time=20 \ s$

If a person is 6.25 m away from a 60.0 w speaker, what is the sound level they are hearing?

vodka [1.7K]

Answer:

110.87 dB

Explanation:

(I got it right on Acellus)

I= P/4(pi)r^2 = 60/4(pi)6.25^2

60/4(pi)6.25^2=0.12223

B=10log(I/Io)

B=10log(0.12223/1*10^-12) = 110.87 dB
