Answer : The money he save in one year would be, $177.009

Explanation :

First we have to calculate the cost of 1 incandescent bulbs.

Cost of 1 incandescent bulbs = Cost of single bulb × Cost of annual operating

Cost of 1 incandescent bulbs = $1.47 × $32.86

Cost of 1 incandescent bulbs = $48.3042

Now we have to calculate the cost of 10 incandescent bulbs.

Cost of 1 incandescent bulbs = $48.3042

Cost of 10 incandescent bulbs = 10 × $48.3042

Cost of 10 incandescent bulbs = $483.042

Now we have to calculate the cost of 1 CFL bulbs.

Cost of 1 CFL bulbs = Cost of single bulb × Cost of annual operating

Cost of 1 CFL bulbs = $3.99 × $7.67

Cost of 1 CFL bulbs = $30.6033

Now we have to calculate the cost of 10 CFL bulbs.

Cost of 1 CFL bulbs = $30.6033

Cost of 10 CFL bulbs = 10 × $30.6033

Cost of 10 CFL bulbs = $306.033

Money he save in one year = Cost of 10 incandescent bulbs - Cost of 10 CFL bulbs

Money he save in one year = $483.042 - $306.033

Money he save in one year = $177.009

Thus, the money he save in one year would be, $177.009

A rock dropped into a pond produces a wave that takes 11.3 s to reach the opposite shore, 26.5 m away. the distance between cons

Kay [80]

The wave takes 11.3 s to cover a distance of 26.5 m, so its speed is:
$v= \frac{S}{t}= \frac{26.5 m}{11.3 s}=2.35 m/s$

The distance between two consecutive crests is 3 m, and this corresponds to the wavelength of the wave. To find its frequency, we can use the relationship between the speed v, the wavelength $\lambda$ and the frequency f:
$f= \frac{v}{\lambda}= \frac{2.35 m/s}{3 m}=0.78 Hz$
