<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>
I am taking an educated guess that he has life insurance
Answer:
By using Pythagoras Formula
Explanation:
Measure the distance man is sliding. “It will be c”
Measure the distance of between the tower and a post with which wire is attached. It will be “b”
Then apply Pythagoras Formula c2=a2 + b2 and solve it.
It will give the height of tower.
Answer:
The wire must be part of a closed circuit.
Explanation:
A closed circuit in electric is what we called a wire that has a complete electrical connection in which electricity flows, where electric current flow from one end to another, in order for magnetism to induce an electric current the circuit has to be closed, or no current will flow.
