Answer:

Work done, W = 36 joules

Explanation:

It is given that,

Force acting on carton, F = 3 N

This force is required to move a carton to a distance of 12 meters

We have to find the work done of the system. It is given by the product of force and distance i.e.

W = F. d

W=3\ N\times 12\ m

W = 36 Joules

So, the work done is 36 joules. Hence, the correct option is (d) ''36 joules''.

A square wave has amplitude 0 V for the low voltage and 4 V for the high voltage. Calculate the average voltage by integrating o
Margarita [4]

Answer:

V_{average} = \frac{1}{2}  V_o  ,     V_{average} = 2 V

Explanation:

he average or effective voltage of a wave is the value of the wave in a period

            V_average = ∫ V dt

in this case the given volage is a square wave that can be described by the function

           V (t) = \left \{ {{V=V_o \ \ \  t<  \tau /2} \atop {V=0 \ \  \ \  t> \tau /2 }   } \right.

to substitute in the equation let us separate the into two pairs

             V_average = \int\limits^{1/2}_0 {V_o} \, dt + \int\limits^1_{1/2} {0} \, dt

             V_average = V_o \ \int\limits^{1/2}_0 {} \, dt

             V_{average} = \frac{1}{2}  V_o

we evaluate  V₀ = 4 V

             V_{average} = 4 / 2)

             V_{average} = 2 V

A bicycle is heading West. It goes 5000m in 500s what's its velocity
dybincka [34]
There are several information's of immense importance already given in the question. Based on the given information's the answer to the question can easily be determined.
Distance covered by the bicycle = 5000 meter
Time taken by the bicycle to reach the distance = 500 second.
Velocity of the bicycle = Distance / Time taken
                                   = 5000/500 meter/second
                                   = 50 meter/second
So the velocity of the bicycle is 50 meter per second. I hope the procedure is clear enough for you to understand. In future you can always use this procedure for solving similar problems.

You walk 10 miles north, 20 miles south, and 5 miles north. Taking north to be the positive y direction, define a position vecto
gulaghasi [49]

Considering north as positive Y axis

       First  10 miles north means a positive 10 displacement along y direction

      Second 20 miles south means a negative 20 displacement along y direction

       Third 5 miles south means a positive 5 displacement along y direction

So total displacement = 10 - 20 + 5 = -5 miles displacement

So position vector of the final position = - 5 j
