Answer:
The answer should be <u>WORK </u>
<em>(Hope this Helps)</em>
Explanation:
work is equal to the product of force and distance.
W=F*S
W=Work
F=Force applied
S=Distance
I believe it would be 4.4
Answer:
Explanation:
The frequency of a light is inversely proportional to its wavelength. It is given by:
The speed of the red light, v = 3.0 × 10⁸ m/s
The wavelength of the red light, λ = 690 nm = 690 ×10⁻⁹ m
Thus, the frequency of red light emitted by neon sign having wavelength 690 nm is
Answer:
See the explanation below.
Explanation:
Indeed this is a serial circuit, in order to calculate the different questions, we must calculate the current of the circuit. The total resistance of the circuit can be calculated by means of an algebraic summation.
Then using ohm's law,we can calculate the current.
Rt = 2 + 4 + 6 = 12 [ohm]
The current
I = V / Rt
I = 12 / 12
I = 1 [amp]
Therefore the voltage in each resistance will be:
V1 = 2 * 1 = 2 [V]
V2 = 4 * 1 = 4 [V]
V3 = 6 * 1 = 6 [V]
The total voltage will be:
V = V1 + V2 + V3 = 12 [V]
The power can be calculated by multiplying the voltage by the total current.
P = V * I
P = 12 * 1
P = 12 [W]
