<span>The law of conservation of mass states that a mass of an object or the amount of matter composed inside an object or thing will not change unless it is added or removed of the matter that is contained in the object itself.

This means that for example, when you're bag has a mass of a 1kg, and you filled it with clothes it will jump its mass from 1kg to possibly 5kg, hypothetically. Thus, withoout the object or clothes that was added the weight of the bad wouldn't change and vice-versa.

Which of the following objects would take you the greatest amount of force to accelerate?
horsena [70]

Complete question is;

Which of the following object would take you the greatest amount of force to accelerate.

A) a soccer ball with a mass of 0.5 kg

B) a refrigerator with a mass of 200 kg, C) a bike with a mass of 25 kg

D) a car with a mass of 5,000 kg,

Answer:

D) a car with a mass of 5,000 kg

Explanation:

Formula for force is;

F = ma

Where;

F is force

m is mass

a is acceleration

Now, Force is directly proportional to the acceleration and mass.

Thus, the higher the mass, the greater the force.

Thus, the object that will require the most force is the one that has the highest mass.

Looking at the options, the one with the highest mass is option D.

If the pressure on a gas sample is tripled and the absolute temperature is quadrupled, by what factor will the volume of the sam
antoniya [11.8K]

Answer:

b. 4/3

Explanation:

Given data

  • Initial pressure: P₁
  • Initial volume: V₁
  • Initial temperature: T₁
  • Final pressure: P₂ = 3 P₁
  • Final volume: V₂
  • Final temperature: T₂ = 4 T₁

We can find by what factor will the volume of the sample change using the combined gas law.

\frac{P_{1}.V_{1}}{T_{1}} =\frac{P_{2}.V_{2}}{T_{2}}\\\frac{P_{1}.V_{1}}{T_{1}} =\frac{3P_{1}.V_{2}}{4T_{1}}\\V_{1} =\frac{3V_{2}}{4}\\V_{2}=4/3 V_{1}
