Answer:
Work is measured as the product of force and the displacement in the direction of the force. Work = force × displacement in the direction of the force.
Answer:
The moment of inertial of the wheel, 
Explanation:
Given;
8 spokes of uniform diameter
mass of each spoke, = 
length of each spoke, = L
mass of outer ring, = 
The moment of inertial of the wheel will be calculated as;
where;
is the moment of inertia of each spoke
is the moment of inertia of the rim
Moment of inertia of each spoke 
Moment of inertial of the wheel
Answer:
He traveled 9km
Explanation:
To do this problem you need to use the equation which is Speed= distance/time and this problem gives you the speed which is 18 km/h and it gives you the time 1/2 hour so you write the equation 18= d/ 1/2 which his distance is 9km
Electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as an output. It was discovered that the above flow of electric charges could be induced by moving an electrical conductor such as a wire that contains electric charges in a magnetic field
