Answer:
Explanation:
Check attachment for solution
Atomic number=Proton count
Atomic mass=Proton count+ neutron count
Neuton Count=Atomic mass-Proton count
Proton count=Atomic number=27
Mass number=74
Neuton count= 74-27=47
The net force would be 75N - 34N = 41N
The crates rate of acceleration would be 41N=8.5*a so a = 4.8m/s^2
Answer:
Electromagnetic wave has longer wavelength.
Explanation:
The velocity (v) of a wave is the product between frequency (f) and wavelength (λ):
(1)
Electromagnetic waves travel on air near the velocity of light
, and sound waves travel on air at approximately
, so if the frequency is equal for both, and the velocity is directly proportional to wavelength as shown in (1) then higher velocities imply higher wavelengths, that is, electromagnetic wave has longer wavelength.
