6. A 50 N block is raised 2 m. If the net work done on the block is 50 J, what is the applied force on the block?

geniusboy [140]

Answer:

F = 75[J]

Explanation:

We know that work is defined as the product of force by distance.

In this way we have two forces, the weight of the block down, and the force that bring about the block to rise.

$W = -(F_{weight*d})+(F_{upward}*d)$

where:

W = work = 50 [J]

d = distance = 2 [m]

Fweight = 50 [N]

Fupward [N]

Now replacing:

$50=-(50*2)+(F_{upward}*2)\\50+100=F_{upward}*2\\F_{upward}=150/2\\F_{upward}=75[J]$

True or False:A wind is a horizontal movement of air from an area of high pressure to an area of lower pressure.

Taya2010 [7]

Answer:

True

Explanation:

When the air blows from high pressure to an area of low pressure over the surface of the earth it is called wind.

The greater the pressure difference more is the speed of the wind. The instrument used to measure the speed of the wind is called an anemometer.

The winds are named after the direction from which they flow.

Calm winds are the slowest of its kind whereas the gale-winds are the strongest winds.
