Answer:

Incoming solar radiations

Explanation:

Weather is defined as the condition of atmosphere at any given time. Weather depends upon the temperature, precipitation, air pressure, and cloud covering.

Daily changes in weather comes because of storms and winds while seasonal changes in weather comes because earth revolves around the sun.

As earth is not flat so, when sun shines near the equator region of earth it becomes warm but the polar region at that time is cold because less solar radiations reach that region. Hence, Incoming solar radiations will be the right answer.

Radio waves transmitted through space at 3.00 ✕ 108 m/s by the Voyager spacecraft have a wavelength of 0.137 m. What is their fr

Answer:

Frequency, $f=2.18\times 10^9\ Hz$

Explanation:

We have,

Speed of radio waves is $3\times 10^8\ m/s$

Wavelength of radio waves is $\lambda=0.137\ m$

It is required to find the frequency of the radio waves. The speed of a wave is given by :

$v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{3\times 10^8}{0.137}\\\\f=2.18\times 10^9\ Hz$

So, the frequency of the radio wave is $2.18\times 10^9\ Hz$ .
