Answer:
e
Explanation:
i took it myself and got it right
V^2 =U^2 +2AS
V^2 = 25 ^2 + 2x9.5x10
V^2 = 625 + 1900 = 2525
V = 50.25
Answer:
about 0.8 times
Explanation: MARS is a planet named after a Roman God of War, it is the fourth planet from the sun and the Second smallest planet following Mercury.
The orbital Speed of a planet is the speed with which the planet uses to completely go round the Sun.
The orbital Speed of the Earth is 29.78kilmeters per Second.
The orbital Speed of Mar is 0.8*29.78kilometers per second/1
=23.824kilmeters per second.
Choorine and sodium.
halite is alos known as sodium chloride.
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
