The voltage provided by the power supply = 20 V
<h3>Resistors in series </h3>
The Voltage across resistors in series in a circuit is equal to the sum of the voltage drops across each resistor.
Therefore for two resistors in series the total voltage provided by the power supply is equivalent to the summation of the voltage drops acroos each resistor ( i.e 10 V + 10 V = 20 V )
Hence we can conclude that the voltage provided by the power supply is 20 V

from kinematics equation if we know that final speed is ZERO and initial speed is given that due to constant deceleration the object will stop in some distance "d" and this distance can be calculated by kinematics


here acceleration due to friction will be same at all different speed
so for 45 km/h speed the distance of stop is 15 m
while at other speed 112.5 km/h the distance will be unknown
now we will have


now divide above two equations


So it will stop in distance 93.75 m
Answer:
A. refraction of light waves
Explanation:
Refraction happens when light travels from one medium to another and changes speed and bends. This also causes objects to look different sizes and shapes when they are submerged in water.

The total current flowing through the circuit <em>I</em> is given

where

Therefore, the total current through the circuit is

In order to find the voltage drop across the 6-ohm resistor, we first need to find the voltage drop across the 1-ohm resistor
:

This means that voltage drop across the 6-ohm resistor
is 20 V. The power dissipated <em>P</em> by the 6-ohm resitor is given by
