Answer:
5.152 A
Opposite to the inner coil
Explanation:
= Vacuum permeability =
= Outer coil current
= Inner coil current = 5 A
= Turns in inner coil = 120
= Turns in outer coil = 165
= Inner radius = 0.012 m
= Outer radius = 0.017 m
Putting the magnetic field as equal we have
The magnitude of current is 5.152 A,
The direction of the current is opposite to that of the inner coil as they have opposing magnetic fields
Y=4x-19
Perpendicular because it has an opposite reciprocal slope
Answer:
Its state is in uniformly accelerated motion
Explanation:
When an object is acted upon the force of gravity only, we said that the object is in free fall.
According to Newton's second law of motion:
where F is the net force on an object, m is its mass, a its acceleration, when the net force on an object (F) is non-zero, than the object accelerates (because a is non-zero), so the object is in accelerated motion.
In case of free fall, the rate of acceleration of the object is equal to , the acceleration due to gravity, and it is constant. So, the object is moving by uniformly accelerated motion.
Answer:
Explanation:
Given that
There's a change in friction from 440 kJ to 110 kJ
This change is as a result of conversion of energy. The energy of the car system converted the mechanical energy in it, into a corresponding heat energy. During the course of this conversion, is where a whopping 330 kJ of energy went missing.
The 330 kJ of energy was lost as a result of the conversion of mechanical energy into heat energy by the use of friction.
