Answer: Heat energy is transferred from warmer objects to cooler objects.
Explanation:
You may confuse two minerals by their colors so using streak is another way for showing their "true colors "
The cat has a speed. The truck and the bicycle both have velocity. We can't be sure of what the plane has.
A scalar quantity is a measurement of a quantity, like temperature, or mass.
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.
