Answer:
B and D
Step-by-step explanation:
One thing is for certain. The final answer will be 1/r^12 or r^(-12)
When written as the given of (r^-4)^3, the powers are multiplied.
The first one is false. There are 4 factors of r^-4 If you get an answer that says it is true, then the question means that r^-4 is 3 equal factors of r^-12
B is true
C: not true. The exponents are multiplied, not added.
D is true
E: not true. This is the same thing as C.
Answer: M = ⁹/₅S
Step-by-step explanation:
M ∞ S -------------------------------- 1
M = KS ------------------------------ 2
K is a constant and need to be calculated
substitute for M and S in 2 to find K
900 = K500
K = ⁹⁰⁰/₅₀₀
= ⁹/₅
Therefore , the equation that connect / relates M to S will be
M = KS
M = ⁹/₅S
We determine the kilowatt-hour by multiplying the energy in kilowatt and the time in hours. We do as follows:
kWh = 110 W ( 1 kW / 1000 W ) (215 hrs )
kWh = 23.65 kWh
Hope this answers the question. Have a nice day.
