Answer:
Actual answers are: Renewable energy supplies may not be completely reliable and It is difficult to generate electricity in large quantities using renewable resources.
Explanation:
For the answer to the question above,
I'll write down my solution to your problem
sin(A+B) = sinAcosB + cosAsinB
<span>sin(2A) = 2sinAcosA </span>
<span>cos(2A) = 1-2sin^2A </span>
<span>sin(3x) = sin(2x+x) </span>
<span>sin(3x) = sin(2x)cos(x) + cos(2x)sin(x) </span>
<span>= 2sin(x)cos(x)cos(x) + (1-2sin^2(x))sin(x) </span>
<span>= 2sin(x)cos^2(x) + sin(x) - 2sin^3(x) </span>
<span>= 2sin(x)(1-sin^2(x)) + sin(x) - 2sin^3(x) </span>
<span>= 2sin(x) - 2sin^3(x) + sin(x) - 2sin^3(x) </span>
<span>= 3sin(x) - 4sin^3(x)
</span>My closest answer is multiple choice letter D.
Answer:
a. 1.0 eV
Explanation:
Given that
Voltage difference ,ΔV = 1 V
From work power energy
Work =Change in the kinetic energy
We know that work on the charge W= q ΔV
For electron ,e= 1.6 x 10⁻¹⁹ C
q=e= 1 x 1.6 x 10⁻¹⁹ C
Change in the kinetic energy
ΔKE= q ΔV
Now by putting the values
ΔKE= 1 x 1.6 x 10⁻¹⁹ x 1 C.V
We can also say that
ΔKE= 1 e.V
Therefore the answer will be a.
a). 1.0 eV
The answer is b. because the heat is even on both when the stream is gone
