Jim pushes hard on a rock that weighs 500 pounds. He pushes with a force of 50 pounds, but the rock doesn't move. How much work
seraphim [82]

Answer:

Zero work

Explanation:

Recall that work done on  an object is defined as the product of the net force applied to an object times the distance it travels in the same direction as the force.

Since in this case Jim used a given force to push a rock, but it didn't move, then he did zero work (because the distance moved is zero).

FromTheMoon [43]

Answer:

a) Mat swum 100 meters.

b)after 4 length , Mat's displacement is zero.

Explanation:

As given, Mat and David are training for the swimming team , and Length of 1 side of the pool is 25 meter.

As swimming pool will be a cube or a cuboid , so it has only 4 sides.

a)

1 length = 23 meter

⇒4 length = 4×25 = 100 meter

So, Mat swam 100 meters.

b)

As after swam 4 lengths of the pool, Mat reaches to its initial position i.e Mat come back to its starting point.

As Displacement is always measures from the starting point.

So, after 4 length , Mat's displacement is zero.

A 208-volt, 4-wire, 3-phase wye power system feeds a school building. Daily voltage readings taken for 1 week are 205.25 volts,
joja [24]

For a 208-volt, 4-wire, 3-phase wye power system feeds a school building, the average daily voltage is mathematically given as

x=206.23v

<h3> What is the average daily voltage of the system?</h3>

Generally, the equation for the mean  is mathematically given as

x=total sum/ number

Therefore

ts=05.25 volts, 203.75 volts, 208 volts, 204.35 volts, 206.7 volts, 207 volts, and 208.55 volts.

ts=1433.6

In conclusion

x=1433.6/7

x=206.23v
