The student concluded that the current in the LDR is inversely proportional to the potential difference across the LDR. Explain
why the student's conclusion is incorrect.
1 answer:
The given question is incomplete as the essential graphical result is missing, however the correct graph is attached with the answer :
Answer:
The correct answer is - According to the graph, the current in the LDR is directly proportional to the potential difference across the LDR.
Explanation:
Two variables that are in directly proportion will consistently deliver a straight-line graph that goes through the beginning. On the off chance that the steady of proportionality is sure, the chart will have a positive slope. On the off chance that the steady is negative, the graph will have a negative angle.
In the given data and graph of the result collected by the student shows a straight line in between the current in the LDR and the potential difference across the LDR. It means they are in relation of directly proportional.
Thus, the correct answer is - According to the graph, the current in the LDR is directly proportional to the potential difference across the LDR.

<u>Answer:</u>
At time 2t the paint ball is at 8 cm to the right and 16 cm to the bottom
<u>Explanation:</u>
We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
Considering the horizontal motion of paint ball
Distance traveled during time t = 4 cm
Initial velocity = u m/s
Acceleration = 0
So
Now at time 2t,
So horizontal distance traveled in time 2t = 8 cm to the right
Now considering the vertical motion of paint ball
Distance traveled during time t = 4 cm
Initial velocity = 0 m/s
Acceleration = -g
At time 2t,
So vertical distance traveled in time 2t = 16 cm to the bottom
