Answer:
B is the answer a force is a push or pull
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:
C and D are correct
Explanation:
An electric dipole moment for pair of equal and opposite charges is defines the magnitude of charge times the distance between them and the direction is always towards the positive charge. According to the definition only points C and D are correct.
C) No net force acts on the electric dipole.
D) There are no electric forces exerted on each pole of the dipole.
When plane is flying in tail wind condition we will have
Now during return journey we can say its would be head wind now
time = 2 + 1 = 2 hours
now add two equations
distance = 360 miles
now from above equation again
Answer:
The distance is
Explanation:
From the question we are told that
The positive charges is
The distance of separation is
Generally at the point where the electric field is zero would be a point where
The electric field due to = The electric field due to
Generally the electric field due to is mathematically represented as
Since we are taking our reference from then the electric field due to is mathematically represented as
So
