Every body in the universe attracts every other body with a force called gravitational force.The gravitational force between two substance are directly proportional to the product of their masses and inversely proportional to the separation distance between them. Mathematically it can be written as -
where m and m' are the masses of two bodies and r is the separation distance between them.
Jupiter is the largest planet in our entire solar system.It has more than 75 moons.Out of all these moons,the four Galilean moons are very large in mass.All others are like simple asteroids.rocks etc whose masses are very small as compared to Galilean moons.These Galilean moons are named as lo,Europa,Ganymede and Callisto.
The lo moon is very close to the Jupiter.The Ganymede moon is the largest moon of the Jupiter which is very big as comparison to mercury also.But it is very far away from Jupiter as compared to lo.
Hence, the force of attraction between Jupiter and lo is very high.It has the greatest gravitational force with Jupiter.
Answer:
200 m/s
Explanation:
Given that,
A plane is moving due north, directly towards its destination. Its airspeed is 200 mph. A constant breeze is blowing from west to east at 60 mph.
We need to find the rate at which the plane is moving towards North. It can be given by :
Where
is the angle with the North
Hence, the plane is moving at a rate of 200 m/s.
Answer:
Explanation:
Given data
Speed of jet Vjet=1190 km/h
Speed of prop driven Vprop=595 km/h
Height of jet 7.5 km
Height of prop driven transport 3.8 km
Density of Air at height 10 km p7.8=0.53 kg/m³
Density of air at height 3.8 km p3.8=0.74 kg/m³
The drag force is given by:
The ratio between the drag force on the jet to the drag force on prop-driven transport is then given by:
