Detailed Answer

One light year is equal to the distance that light travels in one year

(it is about ten trillion kilometers or six trillion miles).

A light year is a unit of distance.

The distance light travels in one year is known as light year.

A light-year is a unit of length used to express astronomical distances and measures about 9.46 trillion kilometers (9.46 x 1012 km) or 5.88 trillion miles (5.88 x 1012 mi)

Explanation

• The SI unit of energy is the Joule (J).
• It is the unit of energy, work, and heat.

Explanation

Explanation

Weight is a vector quantity because it has both magnitude (amount of force) and direction (downward, towards the center of the Earth).

Explanation

The force is acting along the y-axis only, so it has no component along the z-axis.

Answer: 0 N

Explanation

The process in which numbers are assigned to a person's performance is called Measurement

 Measurement refers to the act of assigning numerical values to specific traits or characteristics of an individual, based on a defined set of rules or criteria. 

Explanation

A step-up transformer increases the voltage of the input signal, resulting in a higher voltage output.

This is achieved by having more turns in the secondary coil than in the primary coil.

Explanation

The product RC (Resistance × Capacitance) gives the time constant in an RC circuit.

Its unit is Ohm × Farad = seconds (s), which is the unit of time.

Explanation

The energy stored in a capacitor is given by U = (1/2)CV². If the potential difference (V) is doubled:

U ∝ V²

U' ∝ (2V)² = 4V²

So, the energy stored will increase by a factor of 4.

Explanation

Given the formula and calculation:

F = qE

= (1.6 × 10⁻¹⁹ C) × (1.8 × 10⁻⁸ N/C)

= 2.88 × 10⁻¹¹ N
