You draw a straight line from the start point to the end point. It doesn't matter what route was actually followed for the trip.
The average speed is the distance per time ratio. velocity is the rate at which the position changes
Answer:
R= 5.4 ohms
Explanation:
Given that
V= 9 V
Power ,P= 15 W
Lets take resistor resistance = R
We know that Power given as

V=Voltage
P=Power
R=Resistance

Now by putting the all the values in the above equation

R= 5.4 ohms
Therefore the resistance of the resister will be 5.4 ohms.
<em>mass (m)= 5 kg</em>
<em>height (h)= 9m </em>
<em>gravity (g)= 9.8 m/s^2</em>
It has Potential energy. (PE)
• PE = mgh
Replacing:
PE = 5 * 9.8 * 9 = 441 Joules
