The front brakes on a vehicle do more work than do the rear brakes. technician a says that this is because the front wheel cylinders are closer to the master cylinder than are the rear wheel cylinders. technician b says that this is because the weight of a vehicle shifts to the front during a stop. which technician is correct?

Technician A says that this is because the front wheel cylinders are closer to the master cylinder than are the rear wheel cylinders.

Explanation:

Since the position of cylinder is near the front wheel so the normal force of the front wheel is more than the normal force on the rear wheel

as we know that the center of mass of the wheel is shifted towards the front wheel as the balancing is done with reference to its center of mass

so we will have

also we have

so here we can say

friction force on front wheel will be more

so here front wheel has to do more work to stop the vehicle

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
