Answer:
1.1397 Nm
Explanation:
When the palmaris longus muscle in the forearm is flexed, the wrist moves back and forth.
If the muscle generates a force
and 
, then the torque is equal to 
we see that r = 2.65 cm = 0.0265 m
therefore
torque = 0.0265 x 49.5
= 1.1397 Nm
Answer:
d = 0.05 [m] = 50 [mm]
Explanation:
We must remember the principle of conservation of energy which tells us that energy is transformed from one way to another. For this case, the initial kinetic energy is transformed into useful work that is equal to the product of force by distance.
![E_{k}=F*d\\400 = 8000*d\\d = 0.05 [m] = 50 [mm]](https://tex.z-dn.net/?f=E_%7Bk%7D%3DF%2Ad%5C%5C400%20%3D%208000%2Ad%5C%5Cd%20%3D%200.05%20%5Bm%5D%20%3D%2050%20%5Bmm%5D)
B. they both involve wave interaction.
B.riding on a ferris wheel
E.a satellite orbiting the Earth
Explanation:
A person riding on a ferris wheel and a satellite orbiting the earth both depicts circular motion.
Circular motion is the motion of a body about a fixed axis or center.
- The motion path of the body forms a circle around the center.
- In circular motion, the travel path is along a circle.
- An orbiting satellite traces out its orbit round the earth.
- At certain times, it passes through that point over and over again.
- This is similar to that of a ferris wheel
Other options gives other types of motion.

Answer:
P = 0.6814 MPa
Explanation:
For this exercise we must use the Betuliano relation
P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ rho v₂² + rho g y₂
where we use the subscript 1 for the first pipe and the subscript 2 for the second pipe
indicate that the two pipes are at the same level therefore
y₁ = y₂
P₂ = P₁ + ½ ro (v₁² - v₂²)
let's calculate
P₂ = 13,785 10⁵ + ½ 997 (41,221² - 55,654²)
P₂ = (13.785 - 6.97) 105
P₂ = 6.814 10⁵ Pa
let's reduce to Mpa
P₂ = 6.814 10⁵ Pa (1 MPa / 10⁶ Pa)
P₂ = 6.814 10-1 MPa
P = 0.6814 MPa
