I think your answer is volume
Answer: The correct answer is option(d).
Explanation:
The light given by the combination of the all the seven colors is white color.
Generally white light splits into the band of seven colors when passed through the prism which is known as spectrum.
When the Anna shines a beam of light that includes all the wavelengths of visible light onto the wall she will observe the white light on the wall of the darken room.
Hence, the correct option is (d).
Answer:
Explanation:
F = ma. For us, this looks like
60 = 30a and
a = 2 m/s/s
If the force goes up to, say, 90, then
90 = 30a and
a = 3...if the force goes up, the acceleration also goes up.
If the mass goes up to say, 60, and the force stays the same, then
60 = 60a and
a = 1...if the mass goes up, the acceleration goes down.
Answer:
The power is found to be P = 14250600 W
Explanation:
First we find the voltage or potential difference at the position:
Voltage = Amplitude of Field x Distance
Voltage = V = (0.9 V/m)(42000 m)
V = 37800 volts
Now, we know the formula of electric power is:
Power = Voltage x Current
P = V I
but, from Ohm's Law:
V = I R
I = V/R
Therefore,
P = V²/R
Resistance = real part of impedence = 377 Ω
Therefore,
P = (37800 V)(377 Ω)
<u>P = 14250600 W</u>
