The amount of solute is increased, and the conductivity of the solution is increased
Explanation:
The ability of a solution to conduct electricity is conductivity.The more concentrated a solution is the higher the conductivity.This is because the concentration of ions will increase.Increasing solute increases the concentration of a solution thus rising the conductivity.

Answer:
.864 M
Explanation:
For first order decomposition,
rate constant k = 1/t x ln a / (a - x )
given , a = 1.33 M , t = 644 s , k = 6.7 x 10⁻⁴ , a - x = ? = b( let )
6.7 x 10 ⁻⁴ = 1/644 x ln 1.33/b
ln 1.33/b = 6.7 x 10⁻⁴ x 644 = .4315
1.33 / b = e⁰ ⁴³¹⁵ = 1.5395
b = 1.33 / 1.5395 = .864 M.
What do you mean when you say "this" graph ? I don't see any graph.
First of all, I'm sure you don't have a "velocity versus time" graph.
You may have a "speed versus time" graph, that doesn't show any
information about the direction of the motion.
As you look at your graph ... a feat that's impossible for me ...
-- If the line is horizontal, then speed is not changing. If the direction
of motion is also not changing, then there is zero acceleration. Sadly,
the graph most likely doesn't carry any information about the direction.
It's possible that the speed is constant but the direction is changing.
Then acceleration isn't zero, but you can't tell that from the graph.
-- If the line is proceeding upward from left to right, whether it's straight
or curving, then there is positive acceleration.
-- If the line is proceeding downward from left to right, whether it's straight
or curving, then there is negative acceleration, or what some people might
call "positive deceleration".
Answer:
There are 2.71x10⁴ wavelengths between the source and the screen.
Explanation:
The number of wavelengths (N) can be calculated as follows:
Where:
: is the distance in glass = 2.25 mm
: is the distance in air = 1.50 cm - 0.225 cm = 1.275 cm
: is the wavelength in glass
: is the wavelength in air = 620 nm
To find the wavelength in glass we need to use the following equation:
Where:
: is the refraction index of glass = 1.80
: is the refraction index of air = 1
Hence, the number of wavelengths is:
Therefore, there are 2.71x10⁴ wavelengths between the source and the screen.
I hope it helps you!
