Q. Geosynchronous Orbit
Communications satellites are able to be placed in equatorial orbits at a distance which results in an orbital period of one day. Therefore the satellite occupies a stationary position above the surface of the earth. To determine the height of this orbit we simply equate the centripetal force due to gravity with the centrifugal force resulting from motion along the circular path. Using Me for the mass of the earth and ms for the mass of the satellite, G for the gravitational constant ω for the angular velocity and h for the height of the orbit above the earth's surface
We have
GMems/(Re + h)2= msω2(Re + h)
Then
This is 22,300 mi and quantity to about 5.6 earth radii.
Standing Wave Formation Below given animation depicts two waves moving by a medium in opposite directions. The blue wave is moving to the right and the green wave is moving to
Displacement: - The modification in position of a body in a particular direction is called as displacement. It is a vector function and its unit in SI system is meter. Distanc
A virtual image can be formed by one or more of the following single mirrors? Identify them. a) Plane mirror b) Concave spherical mirror c) Convex spherical mirror
Displacement: - The modification in position of a body in a certain direction is known as displacement. It is a vector function and its unit in SI system is meter.
When reverse bias is enhanced the electric field at the junction also enhances. At some stage the electric field becomes so high that it breaks the covalent bonds building electron
Uses of Transistor: In a transistor the base current it plays a significant role in the collector current IC. A small change in the base current forms a large change in the col
I have 20 ADLC Physics-30 Assignments. Please let me know how much you will charge for this.
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
The device which changes chemical energy into electrical energy is called as electric cell. Battery is a host of constant emf but not constant current.
