Answer:
The star is moving toward us
Explanation:
The wavelength of a distant object changes due to the change in the distance between the observer and the object. This is known as the Doppler effect.
If the wavelength decreases this means that the wavelength in going towards blue which is shorter wavelength. This is known as blue shift. If blue shift occurs then it means that the object is coming closer to the observer.
Hence, the star described here has blue shifted and is moving closer to us.
3. Distance is a quantity that is always a vector.
B.
0.14 (rounded to the nearest hundreth)(full answer: 0.13544323097)
Answer:
The electrostatic potential within the conductor will be negative and constant throughout the conductor.
Explanation:
Whenever a conductor is charged the total charge is spread throughout the entire surface uniformly. Inside the conductor the net electric field is always zero. Also we know if 
e the electric field and V is the potential, then
Now as in this case electric field within the conductor is zero, so potential (V) has to be constant.
Answer:
The answer to your question is given below.
Explanation:
The energy and frequency of a wave are related by the following equation:
E = hf
Where
E => is the energy.
h => is the Planck's constant.
f => is the frequency
From the formula i.e
E = hf
The energy is directly proportional to the frequency. Thus, an increase in the frequency of the wave will lead to an increase in the energy and a decrease in the frequency of the wave will lead to a decrease in the energy.
Considering the question given above, if the frequency of the wave is decreased, then the energy of the wave will also decrease.
