Answer:

Physical.

Explanation:

It is physical because atomic is dealing with something with the elements constructing the substance. Molecular is similar. Chemical is changing the chemical makeup of a substance. So through the process of elimination, it is physical.

If a car has a momentum of 2.04 x 104 kgm/s and a velocity of 18 m/s, what is its mass?

muminat

Answer:

Mass = 1133.33 kg (Approx.)

Explanation:

Given:

Momentum = 2.04 x 10⁴ kg[m/s]

Velocity = 18 m/s

Find:

Mass

Computation:

Mass = Momentum / Velocity

Mass = [2.04 x 10⁴] / 18

Mass = 1133.33 kg (Approx.)

What is the difference between apparent magnitude and absolute magnitude?

Elena-2011 [213]

Here is the difference between apparent magnitude and absolute magnitude. When we say apparent magnitude, this is the measurement of the brightness of the star of how it appears on Earth; on the other hand, absolute magnitude is the measurement of the brightness of the star at a <span>standard distance of 32.6 light years, or 10 parsecs. Hope this answers your question.</span>

A toy car (0.50 kg) runs on a frictionless track and has an initial kinetic energy of 2.2 J, as the drawing shows. The numbers b

steposvetlana [31]

Answer:

Height will be equal to 0.4489 m

Explanation:

We have given mass of the toy m = 0.50 kg

Initial kinetic energy K = 2.2 J

We have to fond the height of the hill over which car roast

When car will roast the hill its kinetic energy will be converted into potential energy and at maximum height all kinetic energy will be converted into potential energy

So at maximum height $mgh=K$

Acceleration due to gravity $g=9.8m/sec^2$

So 0.50×9.8×h = 2.2

h = 0.4489 m
