Bogdan [553]

Answer:

4.58\times 10^{14}Hz 5.825\times 10^{14}Hz 6.31\times 10^{14}Hz

Explanation:

We know that there is a relation between the speed of light ,frequency and wavelength.This relation can be given as v=\nu \lambda where v is speed of light \nu is frequency of light \lambda is wavelength of light

In first case we have given λ=655 nm

so using formula  v=\nu \lambda

3\times 10^8=655\times 10^{-9}\times \nu

\nu =4.58\times 10^{14} Hz

In second case we have wavelength 515 nm so by using above formula

3\times 10^8=515\times 10^{-9}\times \nu

\nu =5.825\times 10^{14}\ Hz

In third case we have wavelength 475 nm

so 3\times 10^8=475\times 10^{-9}\times \nu

\nu =6.31\times 10^{14}Hz

True or false The Coriolis effect is caused by the jet stream.
UNO [17]
The answer is false. The Coriolis effect is not caused by the jet stream. It is caused by the rotation of the Earth. The Coriolis effect is the apparent reversal of rotation of storms and the direction when draining water in the sink or toilet when you cross the equator. In the Southern hemisphere, the rotation is clockwise and in the Northern hemisphere, it's counter-clockwise.

As an auto mechanic, you need to determine the emf and internal resistance of an old battery. you perform these two measurements
stiks02 [169]
We are asked to solve for the internal resistance of the electromotive battery and to answer this we need to apply Ohm's Law which is Voltage is equal to the product of measured current and resistance (V = IR). Thus, to solve for resistance we have it R = V/I where voltage was measured and value is equal to 11.8 volts and current was also measured and the value is 16.5 amperes.

Solving the internal resistance, we have it:
R = V/ I
R = 11.8 volts / 16.5 amperes
R = 0.715 ohms

The answer is 0.715 ohms.
