I believe the stillproud.org is choice B. Together an electron goes near a proton, the force of attraction would increase. Electron is negatively fee while the proton is positively charged so they would certainly naturally tempt each other. Distance and force the attraction is inversely connected so that as the street decreases, the pressure increases.

A water pipe is inclined 40.0° listed below the horizontal. The radius of the pipe in ~ the upper finish is 2.00 cm. If the gauge push a

stillproud.org:

Explanation:

As that is provided that flow rate in the pipeline is 20 cm^3/s

so us have

at the upper finish the area is given as

Also in ~ the various other end

now the rate at 2 ends is given as

now by Bernoulli"s theorem us have

now we have

Now us have

Momentum the red automobile = 5kgm/s

Momentum that blue vehicle = 0kgm/s

Explanation:

Momentum = fixed × velocity

For the red car

Mass = 1kg

Velocity = 5m/s

Momentum that the red auto = 1kg × 5m/s

Momentum that the red car = 5kgm/s

For the blue car.

Mass = 1kg

Velocity = 0m/s(shows that the blue car is stationery)

Momentum = 1kg ×0m/s

Momentum that the blue vehicle = 0kgm/s

Explanation:

The load of a body is identified as the product of massive by the acceleration gravitation of an are or place.

1)

where:

m = mass

g = heaviness acceleration = 9.8

Therefore:

2)

The mass remains the same regardless of wherein the object or body is located. That is, the mass will certainly be same on Mars and also on Earth.

We provided the very same equation to determine the weight, utilizing the Mars gravity constant.
