I would have to go with A, or maybe....yea A
Hey user
The energy E in joules (J) is equal to the voltage V in volts (V), times the electrical charge Q in coulombs (C):
E(J) = V(V) ×<span> Q</span>(C)
So
joule = volt × coulomb
or
J = V × C
Example
What is the energy in joules that is consumed in an electrical circuit with voltage supply of 15V and charge flow of 4 coulombs?
E = 15V × 4C = 60J
A high deductible plan if that person blames you for it and said that it was on purpose
The person running towards the trumpet, Mr. C,
hears a higher frequency.
The person running away from the trumpet, Mrs. B,
hears a lower frequency.
The trumpeter, Mr. A, and the person who is just standing still
and listening, Miss D, both hears the beautiful perfect B-flat.
The frequency of the wave is approximately 25/π Hertz
<h3>Wave function</h3>
The standard wave function is expressed according to the equation
y = Asin(2πft+2πx/λ)
where
λ is the wave length
Given the equation below
y=0.15 sin (0.80x - 50t)
Since 50 = 2πf
For the frequency
2πf = 50
f = 50/2π
f = 25/π Hertz
Hence the frequency of the wave is approximately 25/π Hertz
