Time should not be messed with
for bad things could happen
so think before you act or you'll regret it
Answer:
10 kg
Explanation:
The mass of an object does not change even if the amount of gravtiy changes.
Answer:
10581.59 V
Explanation:
We are given that
Magnetic field=B=0.65 T
Speed of electron=
Charge on electron, 
Mass of electron,
We have to find the potential difference in volts required in the first part of the experiment to accelerate electrons.

Where V=Potential difference
Mass of electron
v=Velocity of electron
Using the formula


Hence, the potential difference=10581.59 V
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
