Answer:
450
Explanation:
total magnification = eyepiece lens x objective lens
10 x 45 = 450
I think the answer may be D- mechanical
Answer:
10 ms⁻¹
Explanation:
The amount of momentum that an object has is dependent upon two factors
- mass of the moving object
- speed of motion
In terms of an equation,
Momentum (P) = Mass(m)×velocity(v)
P = m×v
600 = 60 × v ⇒ v = 10 ms⁻¹
Answer: For producing the error free results of an experiment that identification and quantification of effects of uncertainties are important.
Explanation:
The error analysis is necessary to detect the uncertainties in the measured data or results of the experiment to ensure the validity and acceptability of the results. The errors can be avoided by increasing the precision and accuracy of the measuring instruments. The other factors like changes in the variables of the experiment can also contribute to the errors in the experiment.
It is necessary to perform the multiple trails in an experiment to assure that the results of the experiment are consistent with every trial.
