Answer:
ratio of tangential velocity of satellite b and a will be 0.707
Explanation:
We have given distance of satellite B from satellite A is twice
So
Tangential speed of the satellite is given by
, G is gravitational constant. M is mass of satellite and r is distance from the earth
We have to find the ratio of tangential velocities of b and a
From the relation we can see that tangential velocity is inversely proportional to square root of distance from earth
So
So ratio of tangential velocity of satellite b and a will be 0.707
Answer:
Explanation:
Charge of particle = q
The particles have same charge
r = Distance between charge
k = Coulomb constant =
m = Mass of particle = 10 mg
g = Acceleration due to gravity = 9.81 m/s²
Electrostatic force is given by
According to Newton's second law
Here, both the electrostatic and inertial force is conserved
The charge of the particles is
The charge of the particles is very low as compared to typical static electricity
Answer:
Doubled
Explanation:
F = (kq1q2) / r^2
F and q (Either q1 or q2) are directly proportional, so double the charge would also double the electruc force between the charges.
the reason why sound travels faster in solid is because the molecules in solid is more close to each other and they allow the waves of the sound to travel quickly or easily. and same reason why the sound travels fast in liquid that gas, it's because the molecules in liquid is closer to each other than the molecules in gas but they're not as close as solid hence why solid is the fastest at traveling sound
