F=ma
Force=mass*acceleration
So plug in the values
Hint: the force would be measured in newtons
Answer:
The human ear is not sensitive to every frequency of sound, rather, our hearing range is from 20Hz to 20,000Hz. This means sound frequencies outside this range are not audible to the human ear, which is why not every sound produced is heard. This is quite a blessing because if we could hear every vibrating body, then our ears would never stop listening: we won't be able to distinguish 'important sounds' from unimportant ones, rendering our ears effectively useless. Perhaps this is why we have a hearing range in the first place: sounds of our friends and our foes lie in 20Hz-20kHz range.

Anion is created when electrons are lost.
Answer:
Part 1)
![\tau_1 = 5 \times (0.50) = 2.5 N m](https://tex.z-dn.net/?f=%5Ctau_1%20%3D%205%20%5Ctimes%20%280.50%29%20%3D%202.5%20N%20m)
Part 2)
![\tau_2 = 14 \times (0.30) = 4.2 N m](https://tex.z-dn.net/?f=%5Ctau_2%20%3D%2014%20%5Ctimes%20%280.30%29%20%3D%204.2%20N%20m)
Part 3)
![\tau_3 = 1.4 N m](https://tex.z-dn.net/?f=%5Ctau_3%20%3D%201.4%20N%20m)
Part 4)
Since torque on right side is more so here it will turn and slip over it
Explanation:
As we know that the block A is placed at distance
d = 50 cm from the hinge at 70 cm mark
So torque due to weight of A is given as
![\tau_1 = 5 \times (0.50) = 2.5 N m](https://tex.z-dn.net/?f=%5Ctau_1%20%3D%205%20%5Ctimes%20%280.50%29%20%3D%202.5%20N%20m)
the block B is placed at distance
d = 30 cm from the hinge at 70 cm mark
So torque due to weight of B is given as
![\tau_2 = 14 \times (0.30) = 4.2 N m](https://tex.z-dn.net/?f=%5Ctau_2%20%3D%2014%20%5Ctimes%20%280.30%29%20%3D%204.2%20N%20m)
Now torque due to weight of the scale is given as
![\tau_3 = 7(0.20)](https://tex.z-dn.net/?f=%5Ctau_3%20%3D%207%280.20%29)
![\tau_3 = 1.4 N m](https://tex.z-dn.net/?f=%5Ctau_3%20%3D%201.4%20N%20m)
now torque on left side of scale is given as
![\tau_{left} = \tau_1 + \tau_3](https://tex.z-dn.net/?f=%5Ctau_%7Bleft%7D%20%3D%20%5Ctau_1%20%2B%20%5Ctau_3)
![\tau_{left} = 2.5 + 1.4 = 3.9 N m](https://tex.z-dn.net/?f=%5Ctau_%7Bleft%7D%20%3D%202.5%20%2B%201.4%20%3D%203.9%20N%20m)
Torque on right Side is given as
![\tau_{right} = \tau_2 = 4.2 Nm](https://tex.z-dn.net/?f=%5Ctau_%7Bright%7D%20%3D%20%5Ctau_2%20%3D%204.2%20Nm)
Since torque on right side is more so here it will turn and slip over it
