Answer:
Errors that would be observed as a result of natural input in the field not found in the simulation.
Explanation:
The simulation is a virtual representation of the activities to be experienced in the field, it eliminated natural factors that could affect the result of the experiment in the field. In the field, scientists are able to anticipate errors based on records of natural factors like temperature, humidity, etc, working around it to get the desired result.
Answer:
Explanation:
The formula for the work done on a spring is:
where k is the spring constant and x is the change in length of the string
For the first statement,
x = (a-1.1), W = 5
=> 
Now making k the subject of formula, we have:
For the second statement,
x = (a-4.8), W = 9
=> 
Now making k the subject of formula, we have:
Equating A and B since k is constant, we have:
solving for the value of a
solving for a, we get:
a = 2.6801 or -9.7301
but since length cannot be negative, a = 2.68m
substituting the value of a in equation B, we have:
k = 4.005
