Answer:
The orbital period of the planet would be half that of the earth
Explanation:
From the question we are told that
The mass of star is four times the mass of sun which can be mathematically represented as
Mathematically gravitational potential is given as
Where M is mass one
m is mass two
From this equation we see that the attraction force is directly proportional to the mass of the star
Thus we can say that
The centrifugal force that balances this attraction Force is
Where is the centrifugal acceleration which can be mathematically represented as
and m is the mass
Substituting this into the equation for centrifugal force
substituting into the equation above
Given that the diameter is the same and assuming that the mass is constant
Then
Take square root of both sides
Answer:
D) A warm front brings drizzly weather.
Explanation:
Answer:
Solution given:
frequency[f]=60,500,000Hz
velocity[V]=300,000,000m/s
wave length=?
we have
wave length=
=
==4.96 m
Option A.4.96m
Dominant genes and recessive genes are both given to a parents offspring. However, not both can be expressed causing the difference of dominant and recessive. Dominant genes are more likely to be expressed and recessive genes are more likely to be repressed.
