Answer:False
Explanation:
the intensity of the sound wave decreases with increasing distance from the source.
Choice c) could represent the third step of inquiry.
Explanation:
Inquiry based learning is organized into inquiry phases.
The five general inquiry phase are
Orientation, conceptualisation, investigation, conclusion and discussion.
The investigation phase can be further divided into experimentation phase.
When Andrew washes three separate loads of dirty laundry ,one on hot setting,one one warm setting and one on cold setting , he is experimenting to collect data and interpreting it.
Only if he investigates will he know, which process will be suitable for doling out cleanest clothes.
Answer: 4.27 *10^6 N/C
Explanation: In order to calculate the electric field along the axis of charged ring we have to use the following expression:
E=k*x/(a^2+x^2)^3/2 where a is the ring radius and x the distance to the point measured from the center of the ring.
Replacing the data we have:
E= (9* 10^9* 0.3* 50 * 10^-6)/(0.1^2+0.3^2)^3/2
then
E=4.27 * 10^6 N/C
