Physics
1 answer:
inna [77]3 years ago
4 0

Answer:

-Elasticity will determine how well the particles in the medium bounce back after being disturbed.

-Density will determine how fast the sound will travel; sound travels slower in denser mediums.

-Temperature will also determine how fast sound travels; the lower the temperature, the slower the sound will travel.

In foot x-ray, what is the distance/FFD and Why?
MakcuM [25]

Answer and Explanation:

FFD is the distance between the film on which the image is obtained and the center of the anode tube. The magnification and resolution of the image depends on the FFd By varying the FFD we can change the magnification and resolution of the image. The standard FFD is about 100 centimeters.

New studies have found that by changing the FFD to 130 cm the radiation dosage reduces while the image quality remains practically the same.

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.
