The direction of the magnetic force on the wire is west.
The magnetic force acting on the moving protons acts northward in the horizontal plane. If the thumb is up (current flows vertically up), the wrapped finger will be counterclockwise.
Therefore, the direction of the magnetic field is counterclockwise. Here, the magnetic field is pointing upwards (vertical magnetic field) and the electrons are moving east. Applying Fleming's left-hand rule here, we can see that the direction of force is along the south direction.
As the change in magnetic flux increases upwards, Lenz's law indicates that the induced magnetic field of the induced current must resist and the inside of the loop must be directed downwards. Using the right-hand rule, we can see that a clockwise current is induced.

Answer:
Energy in carriage (Potential energy) = 4,116 J
Explanation:
Given:
Mass of baby = 20 kg
Height = 21 m
Find:
Energy in carriage (Potential energy)
Computation:
The energy accumulated in an object as a result of its location relative to a neutral level is known as potential energy.
In carriage accumulated energy is potential energy.
Energy in carriage (Potential energy) = mgh
Energy in carriage (Potential energy) = (20)(9.8)(21)
Energy in carriage (Potential energy) = 4,116 J
Solar energy is energy that is produced using the sun's rays.
Answer:
With regards to NASA's ambition to send humans to Mars, is an encouraging idea. Also, the aim of sending food supply by unmanned spacecraft before the 2030 project though noble is filled with constraints and design problems.
For the constraints,
1. The spacecraft could be lost on the space before it reaches its destination being Mars. This is because, lack of communication between the control unit on earth and the spacecraft signify it being lost forever.
2. The food supply is bound to spoil on Mars since it would be stored unrefrigerated. This is as a result of the actions of the micro organisms acting on them.
For the criteria for the engineering design problem:
1. The distance between earth and Mars is very far
2. Not factoring in the preservation method into the unmanned aircraft.
