The radii of circular orbits of two satellites A and B of the earth are 4R and R, respectively. If the speed of satellite A is 3 V, the speed of satellite B will be
To understand the relationship between the speeds of two satellites in circular orbits around the Earth, we need to consider their orbital radii. In the given problem, satellite A orbits at radius 4R and travels at a speed of 3V, whereas satellite B orbits at radius R. The speed of a satellite in aRead more
To understand the relationship between the speeds of two satellites in circular orbits around the Earth, we need to consider their orbital radii. In the given problem, satellite A orbits at radius 4R and travels at a speed of 3V, whereas satellite B orbits at radius R.
The speed of a satellite in a circular orbit is dependent on the gravitational pull of the Earth and the radius of its orbit. In general, satellites closer to the Earth have a stronger gravitational force and therefore move at higher speeds. On the other hand, satellites that are farther away have slower speeds.
In this case, we know that satellite B has a radius of R and is much nearer the Earth than satellite A that orbits at 4R. We therefore see that satellite A was moving at 3V, so this immediately tells us how to compute the speed of the motion of satellite B since, having a smaller orbit radius, it will also be orbiting faster. Thus, the speed of satellite B is calculated to be 6V, which is twice the speed of satellite A. This shows the relationship between orbital radius and speed, which indicates that closer satellites must travel faster to maintain their orbits.

Two factors responsible for energy losses in actual transformers are: Core Losses: Due to hysteresis and eddy currents in the core material, resulting in heat generation. Copper Losses: Caused by the resistance of the windings, which generates heat when current flows through them. For more visit herRead more

When a lamp is connected to an alternating voltage supply, it lights with the same brightness as when connected to a 12 V d.c. battery. what is the peak value of alternating voltage source?
When the lamp connected to an alternating voltage supply lights with the same brightness as when connected to a 12 V DC battery, the RMS value of the AC voltage is 12 V. The peak value (V peak ) is √2 × 12 ≈ 16.97V. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/Read more

Which physical quantity remains unchanged in a transformer?
In a transformer, the power (ideally) remains unchanged. The input power in the primary winding is equal to the output power in the secondary winding, assuming no energy losses (ideal transformer condition).

The susceptibility of a magnetic material is – 4.2 × 10⁻⁶. Name the type of magnetic materials it represents.
The susceptibility of −4.2 × 10-⁶ indicates that the material is diamagnetic. Diamagnetic materials have a small negative susceptibility, meaning they are weakly repelled by a magnetic field and do not retain magnetism.
