<span>A favorable entropy change occurs when </span>δ<span>s is positive or when there is an increase in entropy. The concept of entropy tells us that isolated systems tend to go from order to disorder. That is, an increase in entropy means an increase in disorderliness. This is the natural tendency of things. </span>

I need help with nine and 10 I will really appreciate it

Answer:

9] V = D ÷ T

Take any distance value from the graph and its relevant time.

V = 4 ÷ 2

V = 2 m/s

[You will notice that any distance values with its time will give you 2 m/s as its speed. This means that speed is constant throughout.]

10] Take the distance value and its time for the highest peak of B.

V = 20 ÷ 2

V = 10 m/s

How much electrical energy is used by a 400 W toaster that is operating for 5 minutes?

Shkiper50 [21]

The electrical energy consumed by a toaster is 0.033 Kwh.

<u>Explanation</u>:

The power utilized by the toaster is 400 W.

$\text { The power utilized by the toaster is } 400 \mathrm{W} \text { in kilo-watts is } \frac{400}{1000}=0.4 \mathrm{Kw}$

The toaster is operated for 5 Minutes.

$\text { The toaster is operated for } 5 \text { Minutes in hours is } \frac{5}{60}=0.083 \text { hours. (One minute is } 60 \text { seconds) }$

We know that,

$\text {power}=\frac{\text {energy}}{\text {time}}$

Substitute the values in the above formula to obtain electrical energy,

$0.4=\frac{\text { energy }}{0.083}$

Electrical energy = 0.4 × 0.083

Electrical energy is 0.033 Kwh.
