A crane lifts a 6.500 N weight 10 m in 180 seconds. What power is used?

1 answer:

8 0

Power is work over time.

$P= \frac{W}{t}$

We can solve for work by using F*d

$W=F*d = (6.500N)(10m) = 65 J$

Now solve for power:

$P= \frac{(65J)}{180s} = 0.361W

P=0.361W$

Answer:

Frequency, $f=2.18\times 10^9\ Hz$

Explanation:

We have,

Speed of radio waves is $3\times 10^8\ m/s$

Wavelength of radio waves is $\lambda=0.137\ m$

It is required to find the frequency of the radio waves. The speed of a wave is given by :

$v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{3\times 10^8}{0.137}\\\\f=2.18\times 10^9\ Hz$

So, the frequency of the radio wave is $2.18\times 10^9\ Hz$ .
