Yuki888 [10]

Answer:

The answer is "13% and 83%"

Explanation:

The highest power is generated for:

$\to \frac{dP}{dV_a}=0= I_s(e^{\frac{V_m}{V_t}} -1)-I_{Ph} +\frac{V_m}{V_t} I_s e^{\frac{V_m}{V_t}}$

Where voltage, $V_m$ , was its calculated maximum power wattage. This same following transcend national stable coins the power output:

$\to V_m=V_t \ In \frac{1+\frac{I_{ph}}{I_s}}{1+\frac{V_{m}}{V_t}}$

The accompanying consecutive values of $V_m$ are done utilizing iteration and an initial value of 0.5 V:

$\to V_m = 0.5,\ 0.542,\ 0.540 \ V$

Efficacy is equivalent to:

$\eta = |\frac{V_{m} I_{m}}{p_{in}}| =\frac{0.54 \times 0.024}{0.1}=1.3\%$

Currently, $I_m$ was calculated with the formula of voltage $V_m$ (4.6.1) as well as the sun is presumed to produce $100 \frac{mW}{cm^2}$ of power.

The fulfillment factor is equal to:

fill factor $= \frac{V_{m} I_{m}}{V_{oc}I_{sc}}= \frac{0.54 \times 0.024}{0.62 \times 0.025}=83\%$

where open circuit tension of equations (4.6.1) and I = 0. is calculated. The current is equal to the total current of the photo.

nexus9112 [7]

Heat it until it evaporates(Gas) :3
Or freeze it until its ice.(Solid)
its already a liquid normally

Unless you mean like separate the noodles from the broth, in that case use a drainer :'D Jk. I suck at smart stuff.

Room temperature water is placed in an Erlenmyer flask and heated to the boiling point. After the flask is removed from the heat

Vaselesa [24]

Explanation:

When water is boiled in the flask . Some portion of it is evaporated out . Now when cork is placed on it and is placed in the ice box . It cools down , by which the pressure inside decreases .

Due to decrease of pressure , the boiling point of water also decreases . Now it can boil at lower temperature . Thus it starts boiling at lower temperature even , when placed in the ice box .

Gravity accelerates any object falling at 9.8 m/s2. What is the force that will be applied to the ground if an 88 kg box falls f

saw5 [17]

Answer:

The force is of the weight <u>862,4 Newtons.</u>

<u></u>

Explanation:

We have the formula:

w = m * g

Data:

w = weight = ¿?

m = mass = 88 kg

g = gravity = 9,8 m/s

Replacing according formula:

w = 88 kg * 9,8 m/s

Resolving:

w = 862,4 N
