Answer:
82780.42123 m/s
14.45 days
Explanation:
m = Mass of the planet
M = Mass of the star =
r = Radius of orbit of planet =
v = Orbital speed
The kinetic and potential energy balance of the planet and star system is given by
The orbital speed is 82780.42123 m/s
The orbital period is given by
Converting to days
The orbital period is 14.45 days
Answer:
A
Explanation:
a buffer is a chemical substance that maintains a relatively constant pH
The mutual inductance of the two coils is 1.28*10^-3H.
To find the answer, we have to know about the mutual inductance.
<h3>How to find the
mutual inductance of the two coil?</h3>
- We have the expression for emf in terms of mutual inductance and rate of change of current as,
- From the question, it is clear that,
- Thus, the mutual inductance is,
Thus, we can conclude that, the mutual inductance of the two coils is 1.28*10^-3H.

A grandfather paradox is a situation where individual travels to the past and then introduces a change which affects or contradicts the present.
<h3>What is a grandfather paradox?</h3>
A paradox is a situation or statement which involves two contradictions.
A grandfather paradox is a situation which is defined by the ability of an individual to travel to a time in the past usually before the birth of their grandfather and then introduces a change which affects or contradicts the present. For example, killing the grandfather to prevent their birth.
In conclusion, a grandfather paradox is is an event which contradicts the present as a result of a change done to the past.
