Answer with Explanation:
We are given that
Diameter of fighter plane=2.3 m
Radius=
a.We have to find the angular velocity in radians per second if it spins=1200 rev/min
Frequency=
1 minute=60 seconds
Angular velocity=
Angular velocity=
b.We have to find the linear speed of its tip at this angular velocity if the plane is stationary on the tarmac.

c.Centripetal acceleration=
Centripetal acceleration==
Answer:
The torque on the loop is
Nm
Explanation:
Given:
Current
A
Magnetic field
T
Area of loop

Angle between magnetic field and area vector
21°
Form the formula of torque in case of magnetic field,
г
Where
magnetic moment

г 
г 
г
Nm
Therefore, the torque on the loop is
Nm
In a reaction with a directing vendor of the sum forces towards some object or nothing
Reflection. It occurs when a wave bounces from the surface of an obstacle
Reaction time will stay the same for each person however the faster the car is going the faster someones reaction time would need to be react to something that happened. therefore it might seem like someone had a slower reaction time when a car is moving faster because everything happens faster when you are moving faster
I hope I've helped!
