Answer:
The net torque on the square plate is 2.72 N-m.
Explanation:
Given that,
Side = 0.2 m
Force
Force
Force
We need to calculate the torque due to force F₁
Using formula of torque
Put the value into the formula
We need to calculate the torque due to force F₂
Using formula of torque
Put the value into the formula
We need to calculate the torque due to force F₃
Using formula of torque
Put the value into the formula
We need to calculate the net torque on the square plate
Hence, The net torque on the square plate is 2.72 N-m.
Answer:
4.80 seconds
Explanation:
The velocity of sound is obtained from;
V= 2d/t
Where;
V= velocity of sound = 329.2 ms-1
d= distance from the wall = 790.5 m
t= time = the unknown
t= 2d/V
t= 2 × 790.5/ 329.2
t= 4.80 seconds
That information describes the plane's speed.
If he had also told them what direction they were flying, then
they would have been able to put the two pieces of information
together, and they would know the plane's velocity.
