Answer:
Explanation:
Recall that density is defined as and that relative uncertainty is defined as where is the uncertainty in the measure and a the measure, To find the uncertainty when two physical quantities are divided, their relative uncertainties are added and then multiplied with the division result of the quantities.
We have:
To find the percent uncertainty, we multiply the relative uncertainty by 100%.
1. the positioning of the sun
2. equinox
3. summer solstice
Based on the mass of the object, and its acceleration, the time taken to reach a speed of 2.0 m/s is 4 seconds.
<h3>How many seconds will the object take to reach the required speed?</h3>
The time can be found as:
= Required speed / Acceletation
Accelaration is:
= Force / Mass
= (0.99iN + 0jN) / 2kg
= 0.5 ms⁻²
Time taken is:
= 2 / 0.5
= 4 seconds
