Upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure
Lower fixed point is the temperature of pure melting ice.
Answer:
A. Using artificial fertilizers instead of composting
Explanation:
Composting is actually more better than fertilizers usually, as it takes natural waste and with help of nature, returning the nutrients into soil once again. However, Artificial fertilizers usually uses chemicals to ensure that weed does not grow, and may contain other "unnatural" ingredients to ensure that only the crop grows on the field. Because of the usage of non-natural ingredients, any run-off can prove to be detrimental to any animals that eat any of the run-off infected material, or drink the polluted water.

No, that's false. 'Zero' on the Celsius scale

Answer:
a true
Explanation:
Water has the high specific heat capacity.
That means it resists to change its temperature when a considerable amount of heat lost or gained
4200J is needed to raise the temperature of 1kg substance by 1 degree Celsius
Answer:
The answer is 7.52 m/s².
Explanation:
To determine acceleration, N = Ma×g ÷ cos Ф
N sin Ф = ma
a = g Tan Ф m/s²
g = 9.8 m/s² and Ф = 37.5° ( angle for the velocity and gravitational force)
so, a = 9.8 × tan (37.5°)
Acceleration has to be determined in order to get the final answer.
a = 7.5198 m/s²
