Answer:
Replication
Explanation:
<em>The process of running multiple trials for each measurement during an experiment and finding the average is referred to as </em><em>replication.</em>
Replication is one of the attributes of good measurements/experiments because it reduces variability and increases the accuracy of the outcome. It also ensures that relevant statistical analysis can be carried out on the data collected via replicative measurements.
D) earthquakes are caused by movement of the crust along plate boundaries
Answer:
2 N/m
Explanation:
Given that
The length of a wire, l = 15 m
Force on the wire, F = 60 N
Surface tension on the liquid, S = ?
The formula to solve this problem is given as
F = S * 2 L, where
F = force on the liquid
S = surface tension of the liquid
L= length of the wire
On substituting the values of each, we have
60 = S * (2 * 15)
S = 60 / 30
S = 2 N/m
Thus, we can say then, that the surface tension of the liquid is 2 N/m
Answer:
Time period becomes one third
Explanation:
Time period is the reciprocal of frequency
so if frequency is tripled period will be one third.
