<span>we know energy = power*time(in hour)
so energy used by 1.20kw(1200 watt) toast oven used for 6.2 min(6.2/60 hour) =
1200*(6.2/60)=1200*0.103 = 124 watt hour.
Energy used by 11 w cfl used for 8.50 hour = (11*8) + (11* (50/60)) = 88+9.166=97.166 watt hour.</span>
Answer:
Cost = 40 fills
Explanation:
First, we will calculate the total power consumed by all appliances:
Now, we will calculate the energy required:
Now, for the cost we use the following formula:
<u>Cost = 40 fills</u>
The visible spectrum<span> is portion of the </span>electromagnetic spectrum<span> that is </span>visible <span>to the </span><span>human eye.
</span>gamma rays, <span>sound waves, </span><span>microwaves are not the part of spectrum of light, whereas color is the portion of spectrum of light.</span>
Vf= at + Vi
Since at = 8m/s2 * 2 = 16m/s2
Vi=18m/s
=>Vf = 16m/s2 + 18m/s = 34m/s
So, the new velocity is 34m/s
False sometimes you get a bad mutation
