Explanation

Magnetization (M) is the product of the magnetic field intensity (H) and the magnetic susceptibility (χ):

M = χH

Given:

χ = 3.7 × 10^-3

H = 10^4 A/m

M = (3.7 × 10^-3) × (10^4 A/m)

= 37 A/m

Explanation

• The formula for the period of a pendulum is T = 2π√(l/g), where l is the length of the pendulum and g is the acceleration due to gravity.
• Since the mass and diameter are doubled, the acceleration due to gravity (g) on the planet will be half that of Earth.
• Therefore, the new period of oscillation will be √2 times the period on Earth, meaning if it was a second's pendulum on Earth, it will be 2√2 seconds on the planet.

Explanation

• the transfer of heat when waves or rays are dispersed from an object called Radiation
• ***
• different methods of heat transfer
• Conduction is heat transfer through stationary matter by physical contact. 
• Convection is the heat transfer by the macroscopic movement of a fluid.
• Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed.

Explanation

Thermal power generation consists of using steam power 

Thermal energy sources are fossil fuels like:

natural gas, coal, and oil

as well as solar heat

heat pump electric heat

and geothermal heat.

Explanation

If two streams of protons move parallel to each other in the same direction, they repel each other. 

Protons are positively charged particles, and according to Coulomb's law, particles with the same charge repel each other.

This repulsive electrostatic force dominates between the protons, causing them to push away from each other. 

Explanation

The dot product of a vector with itself is equal to the square of its magnitude, or |A|².

The dot product of two vectors A and B is defined as: A · B = |A| |B| cos θ, where θ is the angle between the vectors.

When a vector is dotted with itself, the angle θ becomes 0 (since the vectors are parallel), and cos 0 = 1.

Therefore, A · A = |A| |A| cos 0 = |A|². 

Explanation

The slower motion of a pendulum is due to a longer period, which is related to the weaker gravitational force at higher altitudes

K2, being a very high mountain, has a significantly lower value of acceleration

Due to gravity, cities like Karachi, Murree, or Lahore result in a slower pendulum motion.
