Do you mean rounding if u do then :
rounding to 1.s.f is 5g
rounding to 2.s.f is 5.4 g
rounding to 3.s.f is 5.43g
Answer False
Explanation: Friction makes it stop at some point. For it to have an unlimited speed goes against beset is first law that states an object in motion with stay in motion unless acted upon by an external force, your force will be the friction of the wheels on the roller coaster
Answer:
- <em>As the temperature of a sample of matter is increased, the average kinetic energy of the particles in the sample </em><u>increase</u><em>.</em>
Explanation:
The <em>temperature</em> of a substance is the measure of the <em>average kinetic energy </em>of its partilces.
The temperature, i.e. how hot or cold is a substance, is the result of the collisions of the particles (atoms or molecules) of matter.
The kinetic theory of gases states that, if the temperature is the same, the average kinetic energy of any gas is the same, regardless the gas and other conditions.
This equation expresses it:
Where Avg KE is the average kinetic energy, R is the universal constant of gases, N is Avogadro's constnat, and T is the temperature measure in absolute scale (Kelvin).
As you see, in that equation Avg KE is propotional to T, which means that as the temperature is increased, the average kinetic energy increases.
