The momentum of a 5-kilogram object moving at 6 meters per second is-

Answers

I think the answer is 30 but I’m not sure

The momentum of an object is 30 kgm/s . This can be calculated by using momentum formula see description below.

What is momentum?

It is defined as the product between mass and velocity. Its symbol is p.

It is given by:

p = m * v

What information do we have?

Mass = 5kg

Velocity = 6 m/s

To find:

Momentum=?

On substituting the values:

p = m * v

p =5 kg * 6 m/s

p = 30 kgm/s

Thus, the momentum of an object is 30 kgm/s.

what is the mass of an object if a 30 N force makes it accelerate at 6 m/s2

Answers

Answer:

5 kg

Explanation:

Acceleration = 6 m/s^2

Force = 30 N

Force = mass * acceleration

mass = force / acceleration

mass = 30 / 6

mass = 5 kg

How does Density depend on the type of object being measured ?

Answers

Answer:

ways to exaplined

Explanation:

Density is calculated by

dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL. If both water samples are at the same temperature, their densities should be identical, regardless of the samples' volume.

Explanation:

Coal is formed from the fossil fuel that lie deep beneath the earth crust . These fossil fuels are dead remains of living organism that burried beneath the earth crust million of years ago.

Coal is non renewable because if once it gets depleted it will take a very very long time to replenish.

What type of system would allow light to enter and exit, but would keep any
additional atoms out?

Answers

An isolated system , it does not allow any matter or energy to be exchanged

Answer: it’s closed

Explanation: a pex

Answers

Substance A would have a delta T (change in temp) rise 1/2 the rise in substance B.

Q=mc x delta T

Q= heat energy in Joules
m= mass of substance heated or cooled
c= specific heat
ΔT is change in temp.

Solve for change in temp=. Q/mc

Specific heat and mass are not inversely proportional to heat energy input.

Putting into real world scenario of using water to heat a building.

Specific heat of water is 1.
It takes 1 btu to raise one pound of water 1 degF. at a base of 60 degF

Acetone specific heat is .51

So it takes half the amount of heat input to get a 100 degree ΔT, as compared to water.
