Answer:
The force is 
Explanation:
The moment of Inertia I is mathematically evaluated as
Substituting 
for M(Mass of the wheel) and 
for 
(Radius of wheel)
The torque on the wheel due to net force is mathematically represented as
Substituting 135 N for 
(Force acting on sprocket),
for 
(radius of the chain) and F is the force acting on the sprocket due to the chain which is unknown for now
This same torque due to the net force is the also the torque that is required to rotate the wheel to have an angular acceleration of 
and this torque can also be represented mathematically as
Now equating the two equation for torque
Making F the subject
Substituting values
Answer:
The car C has KE = 100, PE = 0
Explanation:
The principle of conservation of energy states that although energy can be transformed from one form to another, the total energy of the given system remains unchanged.
The energy that a body possesses due to its motion or position is known as mechanical energy. There are two kinds of mechanical energy: kinetic energy, KE and potential energy, PE.
Kinetic energy is the energy that a body possesses due to its motion.
Potential energy is the energy a body possesses due to its position.
From the principle of conservation of energy, kinetic energy can be transformed into potential energy and vice versa, but in all cases the energy is conserved or constant.
In the diagram above, the cars at various positions of rest or motion are transforming the various forms of mechanical energy, but the total energy is conserved at every point. At the point A, energy is all potential, at B, it is partly potential partly kinetic energy, However, at the point C, all the potential energy has been converted to kinetic energy. At D, some of the kinetic energy has been converted to potential energy as the car climbs up the hill.
Therefore, the car C has KE = 100, PE = 0
The correct answer is Matter is made up of atoms and has mass.
The right answer for the question that is being asked and shown above is that: "The image produced is virtual and of the same size as the object." the image if the object is shifted closer to the lens to a point one focal length away from it is that The image produced is virtual and of the same size as the object.<span>
