Answer:
Δf = 0.00003 MHz = 30 Hz
Explanation:
The apparent frequency due to the motion of receiver towards the source is given by Doppler's effect, while the source is stationary. Therefore, the formula is given as follows:
where,
f = apparent frequency
c = speed of light = 3 x 10⁸ m/s
v₀ = velocity of observer = 46 m/s
f₀ = Original Frequency = 175 MHz = 175 x 10⁶ Hz
Therefore,
f = 175.00003 MHz
Therefore, the change in frequency is:
Δf = f - f₀
Δf = 175.00003 MHz - 175 MHz
<u>Δf = 0.00003 MHz = 30 Hz</u>
Every mass is attracted to every other mass with a force that is proportional
to the product of both masses and inversely proportional to the square of the
distance between their centers of mass. The forces act along the line between
their centers of mass.
I’m deciding between E or D.. because for E it’s saying it’s changing ocean currents, but I’m thinking does that mean the earths precipitation or their climate. Best go with E, hope this helps
We will apply the concepts related to energy conservation to develop this problem. In this way we will consider the distances and the given speed to calculate the final speed on the path from the sun. Assuming that the values exposed when saying 'multiply' is scientific notation we have the following,
The difference of the initial and final energy will be equivalent to the work done in the system, therefore
Here,
m = Mass
= Final velocity
G = Gravitational Universal Constant
M = Mass of the Sun
m = Mass of the comet
= Initial Velocity
Rearranging to find the final velocity,
Replacing with our values we have finally,
Therefore the speed is 75653m/s
