Answer:
0.0665 days
Explanation:
We are given;
The mean distance from the Earth's center to the moon;a1 = 385000 km
The mean distance from the Earth's center to the space craft;a2 = 6965 km
Formula for kepplers third law is;
T² = 4π²a³/GM
However, the proportion of both distances would be;
(T1)²/(T2)² = (a1)³/(a2)³
Where;
T1 is the period of orbit of the moon around the earth. T1 has a standard value of 27.322 days
T2 is the period of the space craft orbit.
Making T2 the subject, we have;
T2 = √((T1)²×(a2)³)/(a1)³)
Thus, plugging in the relevant values;
T2 = √(27.322² × 6965³)/(385000)³
T2 = 0.0665 days
Answer:
0.73 W/m²
0.2522 W/m²
Explanation:
= Unpolarized light = 1.46 W/m²
= Analyzer angle = 54°
Light through first filter

The intensity of the light leaving the polarizer is 0.73 W/m²
After passing through analyzer

The intensity of the light that reaches the photocell is 0.2522 W/m²
The group of physicists that failed to obtain the correct measurements failed in obtaining accuracy.
<h3>What is accuracy?</h3>
Accuracy is the state of being accurate; being free from mistakes, this exemption arising from carefulness; exactness; correctness.
Mathematically, accuracy is the exact conformity to truth, or to a rule or model or a degree of conformity of a measure to a true or standard value.
According to this question, a group of physicists perform an experiment. Although the measurements that they took were carefully made, they failed to obtain the correct measurements.
This suggests that the group of physicists failed in obtaining accuracy.
