Pluto is a dwarf planet that's why
Answer:
Mass, m = 27g
Explanation:
<u>Given the following data;</u>
Initial Temperature, T1 = 25°C
Final temperature, T2 = 50°C
Quantity of heat = 2825J
Specific heat capacity of water = 4.184
Heat capacity is given by the formula;
Where,
- Q represents the heat capacity.
- m represents the mass of an object.
- c represents the specific heat capacity of water.
- dt represents the change in temperature.
Making mass, m the subject of formula, we have;
Change in temperature, dt = T2 - T1
Change in temperature, dt = 50-25 = 25°C
Substituting into the equation, we have;
Mass, m = 27g
Therefore, the mass of water that can be added is 27 grams.
Answer:
Actually the object with more mass with the same acceleration will need more force added on to it because it has more mass and more than likely more weight so will need that extra force to push it down the object with the least mass will go faster with the same force added
Explanation:
Answer:
The momentum principle tells us that impulse transfers momentum to an object. If an object has 2 kg m/s of momentum, a 1 kg m/s impulse delivered to the object increases its momentum to 3 kg m/s. That is, pfx = pix + Jx. Just as we did with energy, we can represent this “momentum accounting” with a momentum bar chart.
Answer:
atoms and molecules
Explanation:
as opposed to being continuous or just including particles). On the following page, the idea is stated as one of four concepts in Dalton's theory: “All matter is composed of tiny, indivisible particles called atoms”
