A boat can move at a constant velocity of 8 km/h in still water. How long will it take for the boat to move 24 km?
Elis [28]

Answer: D.) 3hrs

Explanation:

Given the following :

A boat can move at a constant velocity of 8 km/h; How long will it take for the boat to move 24 km

Recall:

Velocity = Displacement / time

For the boat to travel a distance of 24 km at a constant velocity of 8km /hr

Time taken = Displacement(distance moved) / velocity

Time taken = 24km / 8kmhr^-1

Tine taken = 3hrs

he magnetic coils of a tokamak fusion reactor are in the shape of a toroid having an inner radius of 0.700 m and an outer radius
RideAnS [48]

Answer:

B = 4.323 T

Explanation:

We are given;

Inner radius; r_i = 0.7 m

Number of turns; N = 890 turns

Current; I = 17 KA = 17000 A

Formula for the magnetic field inside the toroid along the inner radius is given by;

B = (μ_o × N × I)/(2πr)

μ_o is vacuum of permeability with a constant value of 4π × 10^(-7) H/m

Plugging in the relevant values, we have;

B = (4π × 10^(-7) × 890 × 17000)/(2 × π × 0.7)

B = (2 × 10^(-7) × 890 × 17000)/(0.7)

B = 4.323 T
