1) A ball is thrown with the speed of 10 m/s from the 1st stair. The height of each stair is 10cm and the width is 15 cm. on which stair the ball will fall
Answer:
q = 38,5 kJ
Explanation:
In its melting point, at 0°C, water is liquid. The boiling point of water is 100°C. It is possible to estimate the heat you required to raise the temperature of water from 0°C to 100°C using:
q = C×m×ΔT
Where C is specific heat of water (4,184J/g°C), m is mass of water (92,0g) and ΔT is change in temperature (100°C-0°C = 100°C)
Replacing:
q = 4,184J/g°C×92,0g×100°C
q = 38493 J, in kilojoules:
<em>q = 38,5 kJ</em>

Answer:
Respiration process
Explanation:
Respiration is simply defined as the biochemical process where the body cells derive their energy from the combination of O₂ and food molecules, and in return liberates CO₂, along with some amount of H₂O and energy. This process elaborates on how the tissue cells help in shifting the O₂ from the exterior air into the cells and in return allows the CO₂ to be released outside.
This process is highly essential for an organism to survive. An organism cannot survive without carrying out this process.
