Answer:

a.) negative charge, positive charge

Explanation:

In order to solve this problem, we will need to see the image that can be seen in the attached image.

The point a has a higher potential than point B of the resistance R as the current flows from a to b.

The positive plate of capacitor b has higher potential than the negative plate c.

Once the capacitor has been charged to the nominal value, it will have the same potential of the battery, its terminals will open interrupting the flow of current. But keeping the potential or voltage differential through its points. This will allow the capacitor to work as a battery while discharging.

A given mass of air has a volume of 6.00 L at 101 kPa. At constant temperature, the pressure is decreased to 25.0 kPa. Calculate

Sidana [21]

Answer:

24.24L

Explanation:

According to Boyle's law which states that "the volume of a given mass of gas at constant temperature is inversely proportional to its pressure". Mathematically, P = k/V where;

P is the pressure

V is the volume

k is the proportionality constant

PV = k

P1V1 = P2V2

P1 and P2 are initial and final pressure respectively

V1 and V2 are the initial and final volume respectively

Given P1 = 101kPa V1 = 6.0L, P2 = 25kPa V2 = ?

From the formula;

V2 = P1V1/P2

V2 = 101×6/25

V2 = 24.24L

The final volume for the gas is 24.24L

A cannonball with a mass of 50 kilograms and a golf ball with a mass of 0. 8 kilograms are dropped in a vacuum from a height of

Mnenie [13.5K]

It's gonna take a huge amount of time and effort, and we're gonna spend a huge amount of money, to build a vacuum chamber big enough to do this experiment.

So when we're finally ready to try it, the cannonball and golf ball will make a kind of cute experiment, but let's make it really interesting. Let's ALSO try it with a feather, an apple, a watermelon, a tennis ball, a basketball, a coffeepot, a chair, an old computer, a set of dishes, a trombone, a bicycle, a math book, a TV set, a gallon of milk, a skateboard, a shotgun, a concrete block, a car, a waterbed, a schoolbus, a battleship, your dog, and my wife !

Drop every single one of them from a height of 10 meters.

Every single one of them accelerates at 9.8 m/s² as it falls, takes 1.429 seconds to reach the floor, and hits the floor at a speed of 14 m/s. The feather, the schoolbus, and my wife stay together all the way down.

The only way this doesn't happen is if ...

-- you do this experiment in some other place that's not Earth, or

-- you throw one of the objects and you don't just drop it, or

-- the vacuum chamber has a leak and some air gets into it.

Because that's how gravity works.
