Answer:
Current, I = 1.08 A
Explanation:
Given that,
Length of the copper wire, l = 12 cm = 0.12 m
Mass of the wire, m = 16 g = 0.016 kg
Magnetic field, B = 1.2 T
The magnetic field is oriented perpendicular to the wire. We need to find the current in the wire.
Magnetic force, F = BIL
Force of gravity, F' = mg
F' = F
I = 1.08 A
So, the current through the wire is 1.08 A. Hence, this is the required solution.
Answer:
The acceleration of the plane is 10.93 m/s² at that instant.
Explanation:
Given:
Mass of aircraft,
Downward thrust produced,
Upward resistance force by air,
Weight of the aircraft acting donward,
According to Newton's second law, net force acting on an object is equal to the product of mass and its acceleration.
Here, the net force is given as the difference of downward forces and upward forces.
Now,
Therefore, the acceleration of the plane is 10.93 m/s² at that instant.
