Answer:
2.3 Nm clockwise
Explanation:
Take counterclockwise to be positive and clockwise to be negative.
∑τ = (3 N) (2.5 m) − (7 N) (1.4 m)
∑τ = 7.5 Nm − 9.8 Nm
∑τ = -2.3 Nm
The net torque is 2.3 Nm clockwise.
<u>Answer:</u>
The acceleration of the plane and the time required to reach this speed is (a)= 7.5 
and time(t) = 20 seconds
<u>Explanation:
</u>
Given data Initial velocity 
= 0
Final velocity (
) = 150 m/second
Distance (d) = 1500 m
We have the formula, 
which gives 
= 0+2a(1500)
22500 = 3000 a
acceleration (a) = 7.5 
150 = 7.5 t
t= 150/7.5 = 20
t = 20 seconds.
Answer:
Tech B
Explanation:
There is a revolution of changes occur since the beginning of vehicle creation. Many technology came into existence and proposed us the best design, features and model. But as a machine, several fatigue or wear and tear can happen to this hence a proper maintenance is required in order for smooth running of your vehicle.
Many manufacturers have booklet that mention the proper maintenance interval for better running of your vehicle. As daily environment is changing, the maintenance requirements of a vehicle is also changing. New technology is bringing new features hence their maintenance rate as well as requirement also needs to be upgraded.
