1) newton of the surfaces in contact (the smoothness of the surfaces)
2) how hard the surfaces press together
Answer:
Fatty acids.
Explanation:
-Long term energy storage is stored in the form of triglycerides .
-They are efficient storing molecules. They are more efficient thatn glycogen(cabohydrates).
-Fatty acids are more calori dense hence them being ideal for long term energy storage.
Answer:
Explanation:
Angular momentum has a formula of L = mvr. Fillingin:
L = (1.0)(5.0)(1.0)
L = 5.0 kg*m/s
To solve this problem we will apply the concepts related to the conservation of momentum. This can be defined as the product between the mass and the velocity of each object, and by conservation it will be understood that the amount of the initial momentum is equal to the amount of the final momentum. By the law of conservation of momentum,
Here,
= Mass of Basketball
= Mass of Tennis ball
= Initial velocity of Basketball
= Initial Velocity of Tennis ball
= Final velocity of Basketball
= Final velocity of the tennis ball
Replacing,
Solving for the final velocity of the tennis ball
Therefore the velocity of the tennis ball after collision is 11 m/s
Sample Response: The water is cooler than the sand because it has a higher specific heat value. This means that it takes longer for the water to increase in temperature, making it feel cooler than the sand, which warms up more quickly.
