Answer:
Explanation:
(a). 1 MHz is the frequency of microwave radiation.
(b) 0.167 ms is required by the microwave to travel between two mountains.
Answer:
Explanation:
a. Frequency is the measure of number of times a same thing will be repeated in a given time interval for a given time. And wavelength is the measure of distance between two successive crests or troughs. So wavelength and frequency are inversely proportional to each other. And velocity of light is the proportionality constant.
So frequency of microwave radiation = Speed of light/Wavelength of radiation
Frequency =
Frequency =
So 10 GHz is the frequency of microwave radiation.
b). As microwave is a part of light waves, so it will be experiencing the speed of light.
As the speed is 3* m/s and the distance between the two mountains is given as 50 km, then time can be calculated as
Time = Distance/Velocity
Time =
So time = 0.167 ms.
Thus, 0.167 ms is required by the microwave to travel between two mountains.
Answer:
<em>About four million tons of </em><em><u>matter</u></em><em> are converted to energy in the Sun’s core every second</em>
Explanation:
<u>The Sun </u>
It's estimated that The Sun fuses near 600 million tons of hydrogen into helium every second. As a result, 4 million tons of matter are converted to energy every second according to Einstein's equation
