Answer:
c. 0.12 m/s
Explanation:
by using momentum formula 
we get
Answer:
If the earth stops rotating the apparent weight will increase at most of the places because the upward component of the centrifugal force due to rotation will disappear.
The wavelength of the radio waves is 3.05 m
The relation between wave frequency, wavelength, and speed of light is given as
c=νλ
Plugging the values in the above equation
3*10^8=99.5*10^6*λ
λ=3.015 m
Therefore the wavelength of the radio waves is 3.015 m..
I believe the correct answer is A, Wave 1 has a longer wavelength and a higher amplitude than wave 2. Both A and B are transverse wave, therefore, the wavelength is the distance between two successful crest (highest point) or two successful trough (lowest point). In this case, wave 1 has a longer wavelength than wave 2. Amplitude is the maximum displacement of particles in a wave on either side from the equilibrium point. From the diagram wave 1 as a higher amplitude compared to wave 2.
