Answer:
According to wavelengths in descending order: C, B, D, E and A
According to frequencies in descending order: A, E, D, B and C
According to speeds in vacuum: A =B =C =D =E
Explanation:
in the EM spectrum, radio waves have the longest wavelength while gamma rays have the shortest wavelength.
All EM waves travel with the same speed of in a vacuum.
Answer:
Magnetic force,
Explanation:
Given that,
A beryllium-9 ion has a positive charge that is double the charge of a proton,
Speed of the ion in the magnetic field,
Its velocity makes an angle of 61° with the direction of the magnetic field at the ion's location.
The magnitude of the field is 0.220 T.
We need to find the magnitude of the magnetic force on the ion. It is given by :
So, the magnitude of magnetic force on the ion is .
Answer:
90
Explanation:
The mass number of the missing daughter nuclei can be obtained as shown in the attached photo.
