Erosion can be created from all of them (All of the above)
D. Sometimes it is necessary to put forth new theories to explain experimental results,
Explanation:
Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.
Theories are explanation of scientific observations.
- Most scientists are critical and creative thinkers.
- They must be able to come up with a wide range of possible explanation to explain their findings.
- The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
- Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.

Random errors will shift each measurement from its true value by a random amount and in a random direction. These will affect reliability (since they're random) but may not affect the overall accuracy of a result.
Answer
No you did not lose weight.
Explanation:
Weight is the force acting on an object, Gravity is a force on earth which does not apply to the moon so your weight may change depending in where you are but your mass will stay the same because mass measures the matter of an object ITSELF! Have a nice day....
<h3>
Answer:</h3>
1.93 g
<h3>
Explanation:</h3>
<u>We are given;</u>
The chemical equation;
2C₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l) ΔH = -3120 kJ
We are required to calculate the mass of ethane that would produce 100 kJ of heat.
- 2 moles of ethane burns to produce 3120 Kilo joules of heat
Number of moles that will produce 100 kJ will be;
= (2 × 100 kJ) ÷ 3120 kJ)
= 0.0641 moles
- But, molar mass of ethane is 30.07 g/mol
Therefore;
Mass of ethane = 0.0641 moles × 30.07 g/mol
= 1.927 g
= 1.93 g
Thus, the mass of ethane that would produce 100 kJ of heat is 1.93 g
