Explanation:
It is given that,
Earth's magnetic field, 
Direction of magnetic field, 67.1 degrees below the horizontal, with the horizontal component directed due north.
The magnetic force on the wire per unit length of wire, 
(a) The given scenario is shown in the attached figure as :
Using the right hand rule to find the direction of magnetic force on the wire. By using this rule, we get the magnetic force acting on the wire is in upward direction.
(b) Let I is the current flowing in the wire. The magnetic force is given by the following formula as:
I = 384.61 A
Hence, this is the required solution.

Answer:
Option C. The delivery van has the greatest kinetic energy because its mass is greater than that of the other
vehicles.
Explanation:
Kinetic energy is the energy of an object in motion. Mathematically, it is expressed as:
K.E = ½mv²
Where:
K.E is the kinetic energy.
m is the mass of the object.
v is the velocity of the object.
From the formula above, we can say that:
Kinetic energy is directly proportional to the mass of the object and the square of the velocity of the object. This simply means that objects with higher mass will have a greater kinetic energy than objects will lighter mass even if their velocities are the same.
From the question given above, it is obvious that the delivery van has a greater mass than the rest object.
Therefore, the delivery van will have the greatest kinetic energy because its mass is greater than that of the other
vehicles.
Answer:
Thermal energy is directly related to heat because thermal energy is how heat is transfered.
