Answer:
The rise from A to B is 0.887
Solution:
As per the question:
The following reading of an inverted staff is given as:
A = 2.915
B = -2.028
Here, for inverted staff, the greater reading shows greater elevation and lesser reading shows lower elevation.
Thus
The rise from A to B is given as:
A - B = 2.915 - 2.028 = 0.887

Answer: lambda 
, nu 
, and 100E
Explanation:
The energy 
of a photon is given by:
(1)
Where:
is the Planck constant
is the frequency
On the other hand, we have an expression that relates the frequency of the photn with its wavelength :
(2) where 
is the speed of light
Substituting (2) in (1):
(3) This is the energy for a single photon
For 100 photons, the energy is:
(3)
Where the wavelength and the frequency of the light remains constant.
Therefore, the answer is:
, , and 100E
Answer:
It is doubled.
Explanation:
The EMF( Electromotive force) is usually gotten from an energy source. In this case it is from the magnetic field. However when the other parameters are constant then the main focus is between the EMF and the magnetic field. They have a direct proportion relationship which is why when the magnetic field is doubled the EMF is doubled too.
