'A' and 'C' both show that behavior.

'D' also shows it, but the object is moving backwards when time begins.
First it moves faster and faster backwards, then it moves slower and slower backwards.

What is the S.I. unit of drift velocity and electron mobility?

DanielleElmas [232]

Drift velocity is equal to displacement of the moving object per unit time. The SI unit for displacement is meters while that of time is second. Hence the derived SI unit of velocity is meter per second. This also applies to electron mobility which relates to the displacement per unit time of a moving electron

A window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold welghs 198 N and is 3.2 m long.

iris [78.8K]

Answer:

$T_2 = 309 N$

$T_1 = 489 N$

Explanation:

As we know that total tension in both the ropes is counter balancing the weight of scaffold and worker both

so here we will have

$T_1 + T_2 = (m + M)g$

now we have

$T_1 + T_2 = 198 + 600 = 798 N$

now we also know that net torque due to both tension force in the string with respect to the position of worker must be zero so that platform will remain in equilibrium and horizontal in position

so here we will have

$T_1(1.12) + (198)(1.6 - 1.12) = T_2(3.2 - 1.12)$
