Explanation

- Magnetic Induction (B) is also called Magnetic Flux Density.  

- It represents the strength of the magnetic field over a given area.  

- Unit: Tesla (T) → 1 T = 1 Weber/m²  

- Formula: B = Φ / A  

  (Where Φ = magnetic flux, A = area)  

- It indicates how much magnetic field passes through a surface.  

- It's a vector quantity (has both magnitude and direction).  

- Higher B → stronger magnetic field at that point.

Explanation

A geostationary satellite orbits the Earth once every 24 hours, matching the Earth's rotation.

This keeps it fixed over the same spot on the equator, making it ideal for communication and weather monitoring.

Explanation

A lunar eclipse occurs when the Earth comes between the Sun and the Moon,

And the Earth's shadow falls on the Moon.

- This can only happen during a full moon.

Explanation

To find the resultant magnitude of two forces acting at right angles (90°), use the Pythagoras' theorem:

Resultant (R) = √(F₁² + F₂²)

Given:  

- F₁ = 6 N  

- F₂ = 8 N  

R = √(6² + 8²) = √(36 + 64) = √100 = 10 N

Explanation

All are the units to measure length while length is a distance.

Explanation

The larger numbers are multiples of the smaller numbers before and after.

... 4 20 5 30 6 42 7 56 ...

4 x 5 = 20

5 x 6 = 30

6 x 7 = 42

Explanation

 If a number is evenly divisible by 2 then it's an even number,

otherwise, it's an odd number.

We can also say when we divide a number by 2 and there is some remainder left,

which is not divisible again by 2,

then it's an odd number.
