Answer:
Both the technicians are right so option C is correct

Both the technicians are right so option C is correct
while installing a rebuilt engine, it is necessary to inspect the leaks and proper flow because if there is leak then cooling oil will flow out of the engine which results in engine heating. Secondly flow should be proper otherwise the oil will not reach to all parts and may cause heating of some parts of engine.
If the cooling fan is defective it won't be suck enough heat from engine and it will also cause heating.
6. 0N. This questions requires understanding of how friction functions. Friction is a resistive force, meaning it opposes the direction of any applied or unbalanced forces. The box in the question experiences no horizontal force, so there is no resistive force in response to it, making it 0N.
7. This question tests your understanding of static friction. Static friction only applies when an applied or unbalanced force is applied to an object which does not move. The static friction always equals the magnitude of the applied or unbalanced force component parallel to the surface which the object rests on. The question states that the crate starts to move only when the applied force exceeds 313N, so we use this value to determine the force of static friction. The additional info in the question pertaining to when the crate is moving is irrelevant when determining static friction (only relevant if determining kinetic friction). Knowing this we solve for the weight of the crate:
F = mg
F = (45)(9.8)
F = 441N = Normal Force
The weight of the crate is also equal to the Normal Force since the object rests on a horizontal surface and the applied force is horizontal as well. In this question, since the object is not moving at 313N of applied force, the magnitude of static friction equals the applied force:
Ff = μs * Fn
(313) = μs (441)
0.71 (rounded) = μs
Answer:
if the mass of both objects is doubled, then the force of gravity between them is quadrupled and so on
A convex mirror has a radius of curvature of 30 cm. an object is placed at a distance of 30 cm in front of the mirror. compute the location of the shadows and shadow enlargement!
Mechanical waves transfer energy by including vibration in the propagation medium electromagnetic waves do not require a medium for propagation but still transfer energy by having an electric and magnetic field propagate perpendicular to one another. Hope this helps:)
