Answer:
Option D
Explanation:
As we know
Gravitational Constant (G)
Mass of Earth (M)
Weight of satellite (m) Kg
Radius of Earth (R) =
Distance of satellite from Earth =
Substituting the given values, we get
Km
or 635 m
The correct answer is option D
Altimeters are important navigation instruments for aircraft and spacecraft pilots who monitor their height above the Earth's surface. Skydivers and mountaineers also use altimeters to pinpoint their location in the sky or on the ground.
Your answer is correct the last procedure of a vehicle starting is selecting the appropriate gear for the right situation. (D)
Answer:
b).the kinematic viscosity is absolute viscosity divided by mass density
Explanation:
Viscosity is a fluid property that offers resistance or obstruction to deformation or fluid flow.
Viscosity is of two types--
1. Absolute viscosity , μ
2. Kinematic viscosity, ν
Absolute viscosity :
Absolute viscosity is also called the dynamic viscosity. It is the internal resistance of the fluid to flow.
Kinematic viscosity :
Kinematic viscosity is the ratio of dynamic viscosity to the density of the fluid.
