Explanation:
power of the bulb = 100w=0.1kw
power consumption when the bulb is used for 30 days ( 30 *24 = 720 hours) =0.1*720=72kwh
cost to run the bulb for 30 days = 72*0.18
= $12.96

Answer:
1.25Hz
Explanation:
For waves on a string, the second harmonic is obtained from;
2fo = 1/l √T/M
Where;
l = length of the string
M= mass in kilograms
T = tension in the string
2fo = 1/2√5/0.8
2f0 = 1.25Hz
