<span>First draw a free-body diagram. Torque T = Force F x Distance d where force is the component of gravitational force g and d is the lever arm distance to the pivot point. Since the pivot point is at the back tire we subtract that from the length of the car resulting in d = 1.12 - 0.40 = 0.72 meters = d. We are interested in the perpendicular component of the force exerted on the car jack so use sin 8 degrees then T=1130 kg x 9.81 m/s^2 x sin(8 degrees) x0.72 m = 1,110.80 Newton-meters</span>
Answer:
Explanation:
The final velocity is given by the following kinematic equation:
Here, 
is the initial velocity, a is the body's acceleration and t is the motion time. We have to convert the time to seconds:
Now, we calculate the final velocity:
I think it would be atomic energy, which would most likely be in very short waves to affect the protons.
Answer:
The speed of sound in a rod made of the material is 3215.52 m/s.
Explanation:
The speed of sound can be found using the formula:
Where s is the stiffness, m the atomic mass and d is the length of the interatomic bond.
You just have to correctly replace these values in the formula above.
V= 3215.52 m/s
