Overview. A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Answer:
The net torque about the pivot is and the answer is 'c'
c. ![T_{net}=8.58](https://tex.z-dn.net/?f=T_%7Bnet%7D%3D8.58)
Explanation:
![T=F*d](https://tex.z-dn.net/?f=T%3DF%2Ad)
The torque is the force apply in a distance so it is the moment so depends on the way to be put it the signs so:
![T_1=F_1*d_1](https://tex.z-dn.net/?f=T_1%3DF_1%2Ad_1)
![T_1=7.8N*1.6m=12.48N*m](https://tex.z-dn.net/?f=T_1%3D7.8N%2A1.6m%3D12.48N%2Am)
![T_2=F_2*d_2](https://tex.z-dn.net/?f=T_2%3DF_2%2Ad_2)
![T_2=2.60N**cos(30)*3.0m](https://tex.z-dn.net/?f=T_2%3D2.60N%2A%2Acos%2830%29%2A3.0m)
![T_2= - 3.9 N*m](https://tex.z-dn.net/?f=T_2%3D%20-%203.9%20N%2Am)
Now to find the net Torque is the summation of both torques
![T_{net}=T_1+T_2](https://tex.z-dn.net/?f=T_%7Bnet%7D%3DT_1%2BT_2)
![T_{net}=12.48N-3.9N=8.58N](https://tex.z-dn.net/?f=T_%7Bnet%7D%3D12.48N-3.9N%3D8.58N)
Answer: current I = 0.5 A
Explanation:
Given that the
Potential difference V = 10V
Resistance R = 20 ohms
According to ohms law
V = IR
Where
V = potential difference
I = current
R = resistance
Make I the subject of formula
I = V/R
I = 10/20
I = 0.5 Ampere
