If we increase the length of the resistor, resistance will also increase and vice-versa.

It is given that in a wire simulation, we have to adjust only the length of the resistor.

It required to find the effect on resistor when adjust only the length of the resistor.

<h2>What happens to resistor when adjust only the length of the resistor?</h2>

As we know that the length is directly proportional to the resistance of the wire that means is we increase the size or length of the wire then it also increase the resistance present in the wire. On the other hand if we decrease the length of the wire, it will decrease the resistance. This can be represented as:

Resistance = resistivity × length/area

This is also because there is more collision of the flowing electrons in the wire to the metal ions present there.

Thus if we increase the length of the resistor, resistance will also increase and vice-versa.

Answer:

8000 L/ mol cm is the value of the molar absorptivity coefficient.

Explanation:

The slope of the absorbance- concentration graph is equal to the product of path length and molar absorptivity coefficient.

$\frac{dA}{dc}=\epsilon l$

$\frac{dA}{dc}$ = Rate of change of absorbance with respect to concentration

$\epsilon$ = molar absorptivity coefficient

l = Path-length

Given the slope of graph of absorbance vs procaine hydrochloride concentration.

y = 240000 x (linear equation)

Path length of cuvette = 3 cm

$A=240000 c$

$A=\epsilon c\times l=(\epsilon l)\times c$

$240000=\epsilon \times 3$

$\epsilon =\frac{24000}{3}=8000$

The units of $\epsilon = 8000 l/mol cm$

8000 L/ mol cm is the value of the molar absorptivity coefficient.

Please help!!

Harlamova29_29 [7]

Answer:

This could represent something like sliding a small rock across an icy lake.

Explanation:

A 20N force of gravity (weight), and 20N normal force exerted back onto the object imply it is on the ground and has no vertical motion. There is a net force of 0N

An 80N force to the left and a 5N force to the right create a net force of 75N to the left. This means that there is a force acting on the object that makes it accelerate to the left. 80N represents a push or pull force and 5N represents a relatively small frictional force due to the object being slid on a surface such as steel or in this case ice.

topjm [15]

Answer:

It should be higher during the summer.

Explanation:

Assuming that youlive in the Northern Hemisphere, the sun's location through the season from winter to summer at noon, should be different. The sun would be observed at a higher position over the horizon in the summer season than it is in the winter season. The reasons are equinoxes, solstices and the ecliptic circle.

I hope this answer helps.

What are the three longest wavelengths for standing waves on a 264- cm -long string that is fixed at both ends

miv72 [106K]

The three longest wavelengths for the standing waves on a 264-cm long string that is fixed at both ends are:

5.2 meters.
2.6 meters.
1.7meters.

Given data:

Length of the fixed string = 264cms = 2.64 meters

The wavelength for standing waves is given by:

λ = 2L/n

where,

λ is the wavelength
L is the length of the string

For n = 1,

λ = 2×2.6/1

= 5.2 meters

For n = 2,

λ = 2×2.6/2

= 2.6 meters

For n = 3,

λ = 2×2.6/3

= 1.7 meters
