The momentum of an object depends on which two quantities?
2 answers:
Answer: D) Mass and Velocity
Explanation: Momentum is defined as the tendency of a moving body to keep moving. Thus a body which has mass and is moving will have momentum.
It is denoted by symbol p and the mathematical relation for momentum is mass multiplied by its velocity.
where p= momentum
m= mass of object
v= velocity of object

<u>Answer:</u> The amount of heat required to warm given amount of water is 470.9 kJ
<u>Explanation:</u>
To calculate the mass of water, we use the equation:
Density of water = 1 g/mL
Volume of water = 1.50 L = 1500 mL (Conversion factor: 1 L = 1000 mL)
Putting values in above equation, we get:
To calculate the heat absorbed by the water, we use the equation:
where,
q = heat absorbed
m = mass of water = 1500 g
c = heat capacity of water = 4.186 J/g°C
= change in temperature =
Putting values in above equation, we get:
Hence, the amount of heat required to warm given amount of water is 470.9 kJ
