Answer:
E = 3600 J
Explanation:
Given that,
Voltage, V = 115 V
Power of electric bulb, P = 60 W
We need to find the electric energy used in 1 minute. The electric energy use is given by :

Hence, the electrical energy is 3600 J.
Answer:
588 J
Explanation:
PE (potential energy) = (mass) x (gravity) x (height)
mass = 12 kg
gravity = 9.8m/s^2
height = 5 m
PE = (12) x (9.8) x (5) = 588 J (Joules)
The two types of wave interference are constructive and destructive.
These both describe what happens when waves combine
<u>Constructive interference</u> is when 2 waves combine to form a wave with a larger amplitude, but this is only if both waves are both positive or both negative.
<u>Destructive interference</u> is when the two waves are opposite, one is negative, one is positive. They subtract forming the combined wave that has a lower amplitude.
I hope that helps u out!! :)
V=L•W•H. Sub in what you know: 375=10•5•H. Simplify: 375=50H. Divide by 50: 375/50=H. H=7.5 :)
