What is the closeness of measured value to an accepted value?

What is the colour of third band of a coded resistor having resistance equal equal to 2.3*10`2

Helen [10]

Color of third band of a coded resistor is Brown.

What is Resistance:

Resistance is a measure of the opposition to current flow in an electrical circuit.
Resistance is measured in ohms, omega (Ω)

The color code specify the resistance value, the tolerance, and sometimes the reliability or failure rate.

How to identify resistor's color codes:

Look at the resistor so the group of 3 or 4 color bands are on the left side
Read the color bands from left to right.
Read the color on the last color band, which is farthest right.
compare the colors to the resistance code table

Here,

the value of resistance is 2.3x10^2 Ω

R = 23x10^1 Ω

here power of 10 is 1

so, the color of third band of a color coded resistor will be related to number 1

Hence,

color of third band of a coded resistor is Brown.

How much current will flow through your body if the resistance between your hands is 30,000 ohms and you are connected to 120 vo

Law Incorporation [45]

Resistance of our body is given as

$R = 30,000 ohm$

voltage applied across the body is

$V = 120 V$

now by ohm's law current pass through our body is given by

$i = \frac{V}{R}$

$i = \frac{120}{30,000}[\tex][tex]i = 4 * 10^{-3} A$

So current from our body will be 4 * 10^-3 A

Which is a future NASA research project? Check all that apply.

Nat2105 [25]

All of the given options represent NASA future projects:

Use a probe to collect data- Parker Solar Probe will be the first-ever mission to study the Sun from such a small distance. The spacecraft will travel directly into the Sun's atmosphere about 4 million miles from the surface.

Improve aviation technology- NASA is currently working on the development of the new experimental aircraft X-plane which will prove the dramatic benefits of advanced technologies in piloted flight.

Conduct research from a space station- Humans are already living and working on board of the International Space Station which is one-of-a-kind research laboratory in microgravity. A portion of the astronauts time aboard the space station has been designated for national laboratory investigations.

Collect samples on an asteroid- First asteroid sample return mission, OSIRIS-REx, arrives at the near-Earth asteroid Bennu in December 2018 and should return a sample for study in 2023.

Conduct an unmanned space mission- InSight Mars lander is set to study the planet’s interior. The Mars 2020 rover will search for signs of past microbial life, gather samples for future return to Earth and investigate resources. The James Webb Space Telescope will be the premier observatory of the next decade, studying every phase in the history of our Universe in infrared

An air-filled pipe is found to have successive harmonics at 945 Hz , 1215 Hz , and 1485 Hz . It is unknown whether harmonics bel

Aleonysh [2.5K]

Answer:

L = 0.635m

Explanation:

This problem involves the concept of stationary waves in pipes. For pipes closed at one end,

The frequency f = nv/4L for n = 1,3,5....n

For pipes open at both ends

f = nv/2L for n = 1,2,3,4...n

Assuming the pipe is closed at one end and that velocity of sound is 343m/s in air. If we are right we will obtain a whole number for n.

The film solution can be found in the attachment below.
