Answer;
-Significant
Explanation;
-Several numbers are considered significant in a measurements. Non-zero digits are always significant. Thus, 569 has three significant digits, and 69.35 has four significant digits.
-Zeros are sometimes significant and sometimes aren't:. Zeroes placed before other digits are not significant; 0.0968 has three significant digits.
-Zeros placed between other digits are always significant; 70063 kg has five significant digits. Zeros placed after other digits but behind a decimal point are significant; 7.90 has three significant digits. Zeros at the end of a number are significant only if they are behind a decimal point.

Answer:
See answers below
Explanation:
a.
F = mg,
F = (1500 kg)(9.8 m/s²) = 14,700 N
b.
2500 N - 175 N = 2325 N
Physical properties do not change the chemical nature of matter.
They are things you can observe and touch.
Answer:
mass conservation is valid for all closed system where the mass will remain in the system always
Explanation:
Conservation of mass is applicable everywhere in classical physics
Here we can also apply mass conservation as we know that the initially the beaker and its water content is having total mass of 109.44 g
now when we heated it to higher temperature then its total mass will be lesser than the initial mass this is because some of the water may evaporate from the system.
Here if we repeat the same experiment with closed boundary then we can see that total mass will be conserved
So here mass conservation is valid for all closed system where the mass will remain in the system always
