Answer:
Explanation:
a) Linear density is greater on the left side because the velocity of wave in a string is inversely proportional to the linear mass density of the string
b) We should start pulse from the left hand side so the reflected wave does not get inverted because the wave traveling from the denser to lighter medium gets reflected in the same phase.
Answer:
I think the answer is
C) iron nails are attracted towards all materials
But
- Hence higher the radius lower the voltage
- Lower the voltage higher the capacitance .
<h3>100cm diameter having aluminium sphere has a larger capacitance</h3>
