Near the surface of the earth what is the magnitude and direction of the acceleration due to gravity?

Answers


On the surface of the Earth, the acceleration due to gravity is 

                 9.8 meters/sec²  (rounded)

toward the center of the Earth.

Wherever we are, since that's the direction in which things fall when they're
dropped, we call the direction toward the center of the Earth by the name "down",
although it's a different direction in every place.


Which will have more resistance: 220V, 100W bulb or a 220V, 60W bulb?

Answers

The power dissipated by something with voltage across it is

                     (voltage)² / (resistance) .

You can see that resistance is in the denominator of the fraction,
so larger resistances dissipate less power, and smaller resistances
dissipate more power.

Here's an easy way to remember it: 
-- Connecting a piece of rubber (high resistance) across the terminals of a battery
uses very little power from the battery.
-- Laying a piece of wire (low resistance) across the terminals of a battery
may draw so much power from the battery that the wire melts.


Since the voltage across both bulbs is expected to be the same, the bulb
designed to dissipate 60 watts has higher resistance than the one designed
to dissipate 100 watts.

a moving company is called into a building and asked to relocate 520 bricks to a location 15 meters above the ground if each brick is 4 kilograms what amount of work will be needed to accomplish the task

Answers

Wow ! I'm sweating just thinking about it.


The amount of work required is the additional potential energy

that the bricks will have when they're all up at the higher location.


Increase of potential energy = (mass) x (gravity) x (increase in height)


The total mass is (520 bricks) x (4 kg/brick) = 2,080 kilograms


Potential energy = (2,080 kg) x (9.8 m/s²) x (15 m)


Potential energy = 305,760 Joules.


Grab your hat, put on your sunscreen, and get busy.

Answer:

Work done to lift one brick = 4 Kg x 9.8 m/sec 2 x 15 m = 588 Joules. Then work done to lift 520 bricks = 520 x 588 = 305.760 j
