Answer:
no the moon does the tides. And i think tectonic plats and volcanos and a bunch of other stuff affect the earth
Explanation:
The frequency of the red light is 428 terahertz. To get the value of the red light's frequency, use the formula F = velocity/wavelength. The velocity of light is 3.00 x 10^8 m/s. For easier computation, convert 700.5 nanometers to meter. 1 nanometer is equal to 1 x 10^-9 meters. 700.5 nanometers is equal to 7.005 x 10^-7 meters. Divide the velocity 3.00 x 10^8m/s by wavelength 7.005 x 10^-7 meters. The result will be 4.28 x 10^14 Hertz or 428 terahertz.
Voltage must decrease by a factor of 3 to reduce the current in the resistor by a factor of 3
Answer: Option A
<u>Explanation:</u>
According to ohms law, the voltage passed in a circuit will be directly proportional to the current flow in the circuit. So the resistance of the resistor will act as proportionality constant in ohms law. Let us consider V as original voltage producing a current I in resistor of resistance R. Then according to ohms law:
Now the revised current flow in the circuit is reduced by a factor of 3, So the new current is in the same resistance R, then the new voltage will be
So, the voltage must be reduced by a factor of 3 to reduce the current in the resistor by a factor of 3.
Answer:
False.
Explanation:
Up regulation involves the increase of receptors and it makes the cells more sensitive to the hormones.It's the down regulation that involves the loss of receptors and prevents the target cells from overreacting to persistently high hormone levels.
Answer: The wavelength changes by a factor of
Explanation:
The equation of the speed of a wave is:
Where:
is the speed, that remains unchanged
is the wavelength
is the frequency
Isolating we have:
Now, if we increase the frequency by a factor of 2:
This means the wavelength changes by a factor of
