When considering the gas laws, the kelvin temperature scale must be used. the reason for this is that the kelvin scale is direct

ly proportional to the kinetic energy of the paricles, while the centigrade and fahrenheit scales are not. if you double the temperature of a gas, the pressure will double if volume is held constant. this makes sense if we consider that the particles will be striking the sides of the container with twice as much energy. let's say we want to double 10o
c. the answer would not be 20oc; rather, it will be 293 oc. 10oc is 283 k ( k = oc + 273). doubling 283k gives 566k. converting back to oc gives 293oc. what is the temperature in celcius if we double -6 oc?

aev [14]

Hello!

For the explanation of this energy conservation exercise, where we'll use <u>energy conservation law</u>, let's see what this principle proposes.

How you should know, mechanical energy conserves in every point, that is to say mechanical energy is same in A point like B point. (Mechanical energy will be represented by "Me")

Once time we know that, let's take the 220 Joules momentum like A point, and when 55 Joules momentum like B point.

Then, let's use the <u>energy conservation principle:</u>

Me(A) = Me(B)

  • We know Mechanical energy in A point, so just lets replace according to our data:

220 J = Me(B)

  • In B point, we know kinetic energy, but <u>we dont know gravitational potential energy</u>, so lets descompose Mechanical energy, into kinetic energy and gravitational potential energy:

220 J = Ke + Gpe

  • We know kinetic energy value, so lets replace it:

220 J = 55 J + Gpe

  • Finally, just clean Gpe and resolve it:

Gpe = 220 J - 55 J = 165 J

Gravitational potential energy is of One hundred sixty five Joules <u>(165 J).</u>

Define the term Distance.​
Aloiza [94]

Distance is defined as the space between two points in space.

<h3>What is distance?</h3>

Distance is defined as the space between two points in space.

The unit of distance is metres or kilometres.

Distance can be measured directly usind instruments such as metre rule and tape rule.

The formula for calculating distance is given below:

Distnce = velocity × time.

Therefore, distance is defined as the space between two points in space.

Two masses sit at the top of two frictionless inclined planes that have different angles. Which mass gets to the bottom first?
yulyashka [42]

Answer:

both mass take equal time to reach at bottom

Explanation:

As both masses M 1 and M 2 are situated at same height so that the potential energy at top is transformed to kinetic energy at the bottom by applying principle of energy conservation.

PE = KE

Mgh = (1/2)(M)(V^2)

V^2 = 2gh

V = (2gh)^(1/2)

So velocity is independent of mass

For M1

(M_1)(g)(h) = (1/2)(M1)(V^2)

V^2 = 2gh

V = (2gh)^(1/2)

For M2

(M_2)(g)(h) = (1/2)(M2)(V^2)

V^2 = 2gh

V = (2gh)^(1/2)

therefoer speed at bottom too are independent of mass

So we can say both speed are independent of therir respective mass

hence both take equal time to reach at bottom
