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.
Sound at 70 dB is 70 dB louder than the human reference level. That's 10⁷ times as much as the reference sound power.
Sound at 73 dB is 73 dB louder than the human reference level. That's 10⁷.³ or 2 x 10⁷ times as much as the reference sound power.
Sound at 80 dB is 80 dB louder than the human reference level. That's 10⁸ or 10 x 10⁷ times as much as the reference sound power.
Now we can adumup:
Intensity of all 3 sources = (10⁷) + (2 x 10⁷) + (10 x 10⁷)
Intensity = (13 x 10⁷) times the sound power reference intensity.
Intensity in dB = 10 log (13 x 10⁷) = 10 (7 + log(13)
Intensity = 70 + 10 log(13)
Intensity = 70 + 10 (1.114)
Intensity = 70 + 11.14
Intensity = <em>81.14 dB</em>

Looking at the questioner's profile, I seriously wonder whether I'll ever get a comment in return from this creature, and how I'll ever find out if my solution is correct. For that matter, I'm also seriously questioning how and whether my solution will ever be used for anything.
The speed with which Jennifer climb up the tree is 0.45 m/s
The distance is 10m
Time is 22 seconds
Required speed is 10/22=0.45 m/s
- Distance is the total length travelled by an object.
- Speed is distance upon time.
- It is a scalar quantity and doesn't has magnitude and direction.
- Distance traveled is the total length of the path traveled between two positions
- Distance is the total movement of an object without any regard to direction.
