Without an atmosphere, the equatorial curve would show minimum daily values on the solstices in June when the sub-solar point is located at 23.5°N and in December when the sub-solar point is at 23.5°S latitude.

Explanation:

At the sub-solar point, the sun strikes directly at the surface with an angle of 90 degrees at a given point.

Solistice refers to that point in time when the sun’s zenith is located at the farthest point from the equator.  

During summer solistice on June 21, the sun’s zenith reaches northernmost point, sub-solar point is fixed at 23.5°S Tropic of Cancer making the earth tilt 23.4 degrees

During winter soliscitse on December 21, the sub-solar point is fixed at)  Tropic of Capricorn.

What is the wavelength of the radio waves from an FM station operating at a frequency of 99.5 MHz
ser-zykov [4K]

Answer:

Wavelength, \lambda=3.01\ m

Explanation:

It is given that,

Frequency, f = 99.5 MHz = 99.5 × 10⁶ Hz

We need to find the wavelength of the radio waves from an FM station operating at above frequency. The relationship between the frequency and the wavelength is given by :

c=f\lambda

\lambda=\dfrac{c}{f}{

c = speed of light

\lambda=\dfrac{3\times 10^8\ m/s}{99.5\times 10^6\ Hz}

\lambda=3.01\ m

So, the wavelength of the radio waves from an FM station is 3.01 m. Hence, this is the required solution.

Technician a says multiple discharge ignition system fires the spark plug during each of the engine's four cycle strokes. Techni
patriot [66]

Answer:

Technician B only is correct

Explanation:

Here we have that the multiple discharge ignition system is a system that fires the spark plug multiple times during each power stroke to provide ample spark to complete the ignition. Therefore,  technician A is not correct.

The dual spark plug ignition system is a method if obtaining the ideal combustion and improved fuel consumption than a single spark plug ignition system.

Therefore, only technician B is correct.
