Explanation:
The video camera will record
A ball moving towards the camera, initially faster and then slower.
Since the law of conservation of matter says that no matter can be created or destroyed, chemical equations must have the same amount of matter after the reaction as there was before, making them balanced.
627 J of heat energy is required to warm 10 g of water.
Explanation:
The heat energy required for doing some work is represented as Q. This heat energy will be directly proportional to the product of change in temperature with mass of the object. So the specific heat of the object will act as the proportionality constant.
Thus, it is represented with the symbols Q for hear energy, m for mass of the object, ΔT for the change in temperature and c for specific heat of that object.
Q=mcΔT
As the mass is given as 10g, c is given as 4.18 J/g°C and the change in temperature is ΔT = 25°C-10°C=15°C
So,
Q = 10×4.18×15=627 J
Thus, 627 J of heat energy is required to warm 10 g of water.
Elements are made up of particles.
Burrows, tracks, coprolites, nests and footprints are examples of traces that can be found in a fossil.
