The answer to the question above is "630.25 hours" which is the time to recoup the difference in the water heater cost. This problem can be solved using a simple algebra equation which stated as (18*115*0.1/1000)x - (4*220*0.1/1000)x = $75. In this formula, x represents the time to recoup the difference in the water heater cost (Calculation: 0.207x-0.088x=75 --> 0.119x = 75 --> x = 630.25)<span>. </span>
Answer:
a. s = 0.96 m
b. s = 2.15 m
Explanation:
a.
The relationship between the linear displacement and the angular displacement is given as follows:
where,
s = linear distance covered = ?
r = radius of wheel = (6 in)(0.0254 m/1 in) = 0.1524 m
θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad
Therefore,
<u>s = 0.96 m</u>
<u></u>
b.
Assuming, we have to find linear displacement here, as well:
where,
s = linear distance covered = ?
r = radius of wheel = (13.5 in)(0.0254 m/1 in) = 0.3429 m
θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad
Therefore,
<u>s = 2.15 m</u>
A)At 5.5sec car is at rest because the distance is same as at 5.0sec .
B) At t= 2sec where the distance covered by a car is 20m.
The speed of the car is 10m/s
C) Average speed
4/Savg= 0.14+6.4+5.8+5p.27
Savg = 0.227 m/s
What is non uniform motion ?
When the object is moving with unequal distance along with unequal time intervals.

You could easily help yourSELF if you simply follow the instructions in the question and "Use Ohm's law" to calculate the resistance.
Ohm's Law: Resistance = (voltage) / (current)
Resistance = (10 v) / (5 A)
<em>Resistance = 2 ohms</em>
