Fast need answers Find the amount of force if the body has pressure of 178 Pa on 18 mm²

guajiro [1.7K]

Answer:

Force = 3.204Newton

Explanation:

Given the following data;

Pressure = 178

Area = 18 mm² to meter = 18/1000 = 0.018 m²

To find the force;

Force = pressure * area

Force = 178 * 0.018

Force = 3.204 Newton.

An ac source of period T and maximum voltage V is connected to a single unknown ideal element that is either a resistor, and ind

torisob [31]

Answer:

This satisfy the above given condition so we can say that this capacitor.

Explanation:

Let's take one by one option and check whether is wrong or right

For inductor:

$I=I_osin(wt-\frac{\pi }{2})$

Given that at t=T/4 ,I=0 and we know that

$w=\dfrac{2\pi }{T}$

So at T/4

$I=I_osin(\frac{2\pi }{T}\times \frac{T}{4}-\frac{\pi }{2})$

I=0 A

At t=T/2

$I=I_osin(\frac{2\pi }{T}\times \frac{T}{2}-\frac{\pi }{2})$

$I=I_o$

It means that this not a indutor.

For capacitor:

$I=I_osin(wt+\frac{\pi }{2})$

At T/4, I=0

At t=T/2

$I=I_osin(\frac{2\pi }{T}\times \frac{T}{2}+\frac{\pi }{2})$

$I= -I_o$

This satisfy the above given condition so we can say that this capacitor.

A 1 cm2 silicon solar cell has a saturation current of 10A and is illuminated with sunlight yielding a short-circuit photocurren

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.

What will be the acceleration of an 8 kg object when something hits it with an 12 N force?

liraira [26]

$\sf Force = mass \times acceleration\\\\12~N = 8~kg \times acceleration\\\\ acceleration = \frac{12~N}{8~kg} \\\\\boxed {\sf a = 1.5~ \frac{m}{s^2} }$
