The power equals energy divided by the time
P=E/t
P=1200/60
P=20W
Hope you get it!
Answer:
x-component of force is 38.18 lb where as magnitude of Force is 93.16
Explanation:
Fy of the force F exerted on the handle of the box wrench = 86 lb
Considering the triangle in Fig 1
magnitude of perpendicular = P = 12
magnitude of base = B = 5
using Pythagoras theorem
![H= \sqrt{P^{2} + B^{2}}](https://tex.z-dn.net/?f=H%3D%20%5Csqrt%7BP%5E%7B2%7D%20%2B%20B%5E%7B2%7D%7D)
![H= \sqrt{12^{2} + 5^{2}}](https://tex.z-dn.net/?f=H%3D%20%5Csqrt%7B12%5E%7B2%7D%20%2B%205%5E%7B2%7D%7D)
![H=13\\\implies cos \theta = \frac{5}{13} \\\implies sin \theta = \frac{12}{13}\\](https://tex.z-dn.net/?f=H%3D13%5C%5C%5Cimplies%20cos%20%5Ctheta%20%3D%20%5Cfrac%7B5%7D%7B13%7D%20%5C%5C%5Cimplies%20sin%20%5Ctheta%20%3D%20%5Cfrac%7B12%7D%7B13%7D%5C%5C)
y-component of force is given given as:
![86 = Fsin\theta\\F = 86 (\frac{13}{12})\\F = 93.16 lb\\F_{x} =F cos \theta\\F_{x} = 93.16 (\frac{5}{13})\\F_{x} =38.18 lb.](https://tex.z-dn.net/?f=86%20%3D%20Fsin%5Ctheta%5C%5CF%20%3D%2086%20%28%5Cfrac%7B13%7D%7B12%7D%29%5C%5CF%20%3D%2093.16%20lb%5C%5CF_%7Bx%7D%20%3DF%20cos%20%5Ctheta%5C%5CF_%7Bx%7D%20%3D%2093.16%20%28%5Cfrac%7B5%7D%7B13%7D%29%5C%5CF_%7Bx%7D%20%3D38.18%20lb.)
Answer:
Option C is correct.
The component of acceleration perpendicular to an object’s velocity tells us How the object’s direction changes.
Explanation:
This acceleration is called radial/tangential acceleration. It is the reason why a body moving in circular motion with constant velocity can be said to also be accelerating because its direction is continuously changing. The acceleration is usually directed towards the centre of the circular motion of the body or trying to throw the body off its circular motion path.
