Answer:
HELLOO
The Richter scale rates the amount of energy released from a single earthquake, letting us know the magnitude of the disaster. A seismograph is what scientists use to actually measure the earthquake and the Richter scale is a way of putting the data into an understandable context.

Explanation:
Why do your lights actually come on almost instantaneously? ... Wiring the house in parallel does not make a difference – there is no current flowing through the light bulb when the switch is off no matter how the house is wired. If there were a current already, the light would be on!
Answer:
V = I R
expression does not depend on the frequency, so when changing this quantity does not change the voltage or the current in the circuit.
Explanation:
In a purely resistive circuit, the Ohm relation, m for which
V = I R
We see that the previous expression does not depend on the frequency, so when changing this quantity does not change the voltage or the current in the circuit.
This does not happen in circuits with capacitors or inductors where there is an explicit dependence on frequency.
Answer:
Focal length, f = 0.43 meters
Explanation:
It is given that,
Power of the reading glasses, P = 2.3 D
We need to calculate the focal length of the reading glasses. The relationship between the power and the focal length inverse i.e.
f = 0.43 m
So, the focal length of the reading glasses found on the rack in a drugstore is 0.43 meters.
