Find the voltage

Physics
1 answer:
son4ous [18]2 years ago
5 0

Answer:

Explanation:

solve the parallel resistances

30||40     and 50||30

17.14285714   and 18.75

total Resistance = 35.89285714

V = IR

9V = I *35.89285714

9V / 35.89285714 = I

0.250746 = I

Now use the resistance across AB

V = 17.14285714 * 0.250746

V = 4.29850

this is the Voltage drop across AB  :P

The velocities of light in air and glass are 3.0 x 10^8ms and 2.0×10^8ms respectively. If the angle of refraction is 30°, the si
JulijaS [17]

Answer:

0.75

Explanation:

refractive \: index \:  =  \frac{3.0 \times  {10}^{2} }{2.0 \times  {10}^{2} }

= 1.5

refractive \: index =  \frac{ \sin(angle \: of \: incidence) }{ \sin(angle \: of \: refraction) }

1.5 =  \ \frac{ \sin(i) }{ \sin(30) }

1.5 × ½ = sin(i)

\sin(i)  =  0.75

2. Jenny picks up a guitar and strums. If the sound from the string emanates out at 440 Hz,
erik [133]

Answer:

6.8×10^6 m

Explanation:

f = velocity of light/ wavelength

440= 3×10^8 / wavelength

so

wavelength = 3×10^7/ 44

= 6.8×10^6 m

Although the reactions of the calvin cycle do not depend directly on light. True or False
Harlamova29_29 [7]

Answer:

True

Explanation:

The complete question is:

<em>"Although the reactions of the Calvin cycle do not depend directly on light, they do not usually occur at night. True o False"</em>

<em> </em>The Calvin cycle is also known as the Calvin-Benson cycle or as the CO₂ fixation phase in the photosynthesis process.

The Calvin cycle generates the reactions necessary to fix the carbon in a solid structure for the formation of glucose and, in turn, regenerates the molecules for the continuation of the cycle.

The Calvin cycle is known as the dark phase of photosynthesis, or the carbon fixation phase. It is called the dark phase because this cycle is not dependent on light like other parts that make up the photosynthesis process. But it uses the energy that is produced in the light phase of photosynthesis to fix carbon.

It can be said that it consists of or forms the second stage of photosynthesis, in which the carbon of the carbon dioxide that is absorbed is fixed.

So, the statement is true because the Calvin cycle uses the energy that is produced in the light phase of photosynthesis to fix carbon.

A wavelength approaching land at 25 m/s is 4.0 x 102 m. What is its period?
kherson [118]

Answer:

16 s

Explanation:

The frequency of a wave is the number of oscillations of the wave per second. It is given by:

f=\frac{v}{\lambda}

where

v is the wave speed

\lambda is the wavelength

For the wave in this problem we have

v = 25 m/s

\lambda=4.0\cdot 10^2 m=400 m

So the frequency is

f=\frac{25}{400}=0.0625 Hz

The period of a wave is the time taken for one complete oscillation, and it is equal to the reciprocal of the frequency:

T=\frac{1}{f}

So the period of this wave is:

T=\frac{1}{0.0625}=16 s
