The phenomenon of a changing magnetic field inducing an electric field is described by Faraday's law of induction.

W = F * d = (E * q) * d = (500 N/C * 4 × 10^-6 C) * 0.2 m = 0.4 J.

A charged particle moving perpendicular to the magnetic field will follow a circular path due to the magnetic force acting as a centripetal force.

A charged particle moving perpendicularly to a magnetic field experiences a magnetic force that acts as a centripetal force, causing it to move in a circular path.

A charged particle moving in a magnetic field experiences a force that is perpendicular to its velocity, resulting in circular motion.

A charged particle moving perpendicular to a uniform magnetic field will move in a circular path due to the magnetic force acting as a centripetal force.

Using Pythagoras theorem: r² = (10/2)² + 6²; r² = 25 + 36 = 61; r = √61 ≈ 10 cm.

Using Pythagoras theorem: r² = (5)² + (6)² = 25 + 36 = 61; r = √61 ≈ 7.81 cm.

Circumference = πd = π * 10 = 31.4 cm.

Circumference = πd = π * 20 = 62.8 cm.

Diameter = 2 * radius = 2 * 10 cm = 20 cm.

Diameter = 2 * radius = 2 * 12 = 24 cm.

Diameter = 2 * radius = 2 * 3 cm = 6 cm = 60 mm.

Diameter = 2 * radius = 2 * 3 m = 6 m.

Arc length = (θ/360) * 2πr; = (60/360) * 2π * 5 = 10.47 cm.

Arc length = (θ/360) * 2πr = (60/360) * 2 * π * 5 = 5.24 cm.

Arc length = (θ/360) × 2πr; = (60/360) × 2π × 5 ≈ 5.24 cm.

Area = πr². Therefore, r = √(Area/π) = √(154/3.14) ≈ 7 cm.

Area = πr². Therefore, r = √(Area/π) = √(154/3.14) ≈ 7 cm.

Area = πr². Therefore, r² = Area / π = 78.5 cm² / 3.14 = 25. r = √25 = 5 cm.

Area = πr². Therefore, r² = Area / π = 78.5 cm² / 3.14 = 25. r = √25 = 5 cm.

Radius = 10/2 = 5 cm; Area = πr² = π * 5² = 78.5 cm².

Radius of the circle = side/2 = 10 cm / 2 = 5 cm. Area = πr² = 3.14 * 5² = 78.5 cm².

Radius = 8/2 = 4 cm; Area = πr² = π * 4² = 50.24 cm².

Total resistance R = 3Ω + 6Ω = 9Ω. Current I = V/R = 9V / 9Ω = 1A.

The voltage drop across the resistor is equal to the battery voltage, which is 15V.

Using Ohm's law, I = V/R = 24V / 12Ω = 2A.

Using Ohm's law, I = V/R = 24V / 6Ω = 4A.

First, find the equivalent resistance: 1/R_eq = 1/5 + 1/10 = 3/10, so R_eq = 10/3Ω. Then, I = V/R_eq = 20V / (10/3)Ω = 6A.

Total resistance R = 3Ω + 6Ω = 9Ω. Current I = V/R = 9V / 9Ω = 1A.
