Explanation

• A simple refracting telescope uses lenses to view distant objects.
• It has two convex lenses: objective lens and eyepiece.
• The objective lens forms a real image.
• The eyepiece magnifies the image for viewing.

Explanation

• Celsius and Fahrenheit are two temperature scales.
• At one special point, both scales show the same value.
• This happens when temperature is −40.
• So, −40°C = −40°F.

• Energy due to motion is called kinetic energy.
• Any moving object possesses this energy.
• It depends on mass and velocity of the body.
• Faster motion means more kinetic energy.

Explanation

For capacitors in series:  

1/Cₑq = 1/C₁ + 1/C₂ 

1/Cₑq = 1/4 + 1/4 = 2/4 = 1/2

Cₑq = 2 µF

Explanation

• Sound travels in air at a moderate speed.
• At room temperature (about 20°C), it is around 340 m/s.
• This value can slightly change with temperature.

Explanation

Momentum is the product of mass and velocity.

Formula: 𝑝 = 𝑚𝑣

Mass = 0.5 kg, Velocity = 4 m/s

So, momentum = 0.5 × 4 = 2.0 Ns
