Explanation:
∆x=300 m×2
∆t=1.5 s
v=∆x/∆t → v=2×300/1.5 = 400 m/s
Air pressure is proportional to the square of the wind velocity.
Wind speed is how fast wind goes and atmospheric pressure is the pressure that the atmosphere pushes on us. The greater the difference in barometric pressure from a high pressure zone to a low pressure zone, the greater the wind velocity will be.
Hope this helped!
I think b but I’m not completely sure
As we can see here the lever has two forces at two ends
1. 300 N
2. 200 N
now we need to find the Torque on the lever about the fulcrum
so we will have
1. clockwise torque due to force at right end is


2. counterclockwise torque due to force at left end


so as per above calculations we can see that net torque on the lever is clockwise as it has more torque in clockwise direction
so <u>it will rotate clockwise</u>
