The amount of energy used in the billing period is 5,400,000,000 joules.
One kWH is the amount of energy transferred in one hour, there 1 kWh is equal to
1 kWh=1*1000*(J/s)*3600 s
=3600000 J
Thus the amount of energy in joules consumed by the user for the billing period is =1500*3600000=5,400,000,000 J.
The amount of energy used in the billing period is 5,400,000,000 joules.
No, she has it backward. Waves interfere with each other and reflect off objects. When two waves overlap their amplitudes add. If they have the same sign this addition is constructive, meaning the amplitudes grow. If they have opposite signs this constitutes subtraction and the waves can partially, or completely cancel. This is known as interference. Reflection occurs when waves travel from one medium to another. If the wave impedance of the new medium is different (which it generally is) there will be a partial, or even total, reflection.
Answer:
asteroids are broken pieces of rock and are small compared to actual planets also asteroids travel in "belts" and not there own course
Explanation:
that was my best suggestion
Answer:
The original concentration of ethanol is 16%(v/v)
Explanation:
concentration before dilution, C1 = ?
Concentration after dilution, C2 = 0.32% (v/v)
Volume before dilution, V1 = x
Volume after dilution, V2 = 50x
From the dilution principle
C1V1 = C2V2
(C1) * x = (0.32) * 50x
C1 = (16x)/x
C1 = 16%(v/v)
