Answer:
It is because it cannot be used time again and again.
Electromagnetic radiation are represented in waves. Each type of wave has a certain shape and length. The distance between two peaks in a wave is called the wavelength. This value is equal to the speed of light divided by the frequency.
Wavelength = c/f
Wavelength = 3x10^8 / <span>5.42x10^15
</span><span>Wavelength = 5.54 x 10^-8 m = 55.35 nm</span>
Answer:
It looks like its moving north.
Explanation:
The intensity of most cyclones reduces after hitting land
because land takes away the heat and moisture of tropical ocean water. In order
to survive, cyclone storms need evaporation from the warm sea surface. Intensity
also decreases because of greater fiction on land, compared to the sea surface.
Answer:
Explanation:
Given
Total run=198 m
maximum speed=317 m/min=5.28 m/s
acceleration
(a)Distance traveled while accelerating
s=12.57 m
time taken
v=u+at
t=4.75 s
(b)Time taken to cover 198 m
if car takes 12.57 m & 4.75 s to reach max speed so it also takes 12.57 m and 4.75 s to stop from max speed
Distance traveled with max speed=198-25.14=172.86 m
time taken
total time=4.75+32.73+4.75=42.25 s
