Answer:

The difference between the Electrolyte and Non-Electrolyte are given in the explanation part.

Explanation:

ELECTROLYTES are salts or molecules which ionize in solution fully.
Electrolyte solutions thus conduct electricity readily.

whereas

NON ELECTROLYTES in water do not dissociate from ions,
non-electrolyte solutions do not conduct electricity.

What instrument can break down electromagnetic light into its constituent parts?

Dimas [21]

C. Spectroscope

Spectroscope is the instrument that can break down electromagnetic light into its constituent parts.

It is a device that helps us identify what things are made out of. It takes the light and splits it up into its component colors.

Suppose that the speed of an electron traveling 2.0 km/s is known to an accuracy of 1 part in 105 (i.e., within 0.0010%). What i

Answer: $2.89(10)^{-3} m$

Explanation:

The <u>Heisenberg uncertainty principle</u> postulates that the fact each particle has a wave associated with it, imposes restrictions on the ability to determine its position and speed at the same time.

In other words:

It is impossible to measure simultaneously (according to quantum physics), and with absolute precision, the value of the position and the momentum (linear momentum) of a particle. Thus, in general, the greater the precision in the measurement of one of these magnitudes, the greater the uncertainty in the measure of the other complementary variable.

Mathematically this principle is written as:

$\Delta x \geq \frac{h}{4 \pi m \Delta V}$ (1)

Where:

$\Delta x$ is the uncertainty in the position of the electron

$h=6.626(10)^{-34}J.s$ is the Planck constant

$m=9.11(10)^{-31}kg$ is the mass of the electron

$\Delta V$ is the uncertainty in the velocity of the electron.

If we know the accuracy of the velocity is $0.001\%$ of the velocity of the electron $V=2 km/s=2000 m/s$ , then $\Delta V$ is:

$\Delta V=2000 m/s(0.001\%)$

$\Delta V=2000 m/s(\frac{0.001}{100})$

$\Delta V=2(10)^{-2} m/s$ (2)

Now, the least possible uncertainty in position $\Delta x_{min}$ is:

$\Delta x_{min}=\frac{h}{4 \pi m \Delta V}$ (3)

$\Delta x_{min}=\frac{6.626(10)^{-34}J.s}{4 \pi (9.11(10)^{-31}kg) (2(10)^{-2} m/s)}$ (4)

Finally:

$\Delta x_{min}=2.89(10)^{-3} m$

How do amplitude and frequency affect light energy? help asap !!!!!!

Lubov Fominskaja [6]

So, I’m assuming that we’re treating light as a propagating wave.

Amplitude measures the amount of energy transported by a wave, thus amplitude squared is directly proportional to the light’s energy. The higher the amplitude, the higher the energy.

Energy is also directly proportional to the frequency of a wave, the higher the frequency, the higher the energy.

I took my second answer from the formula below:

E=cf

What happens when your wearing socks and you shuffle across a carpet then touch a door knob?

natali 33 [55]

Answer:

You build up kinetic energy and you get shocked this happens because static has built up from the socks and the rug. This also happens when you rub a balloon on your head or shuffle across a trampoline with socks on.

A student was given a sample of crude acetanilide to recrystallize. The initial mass of the the crude acetanilide was 166 mg. Th

padilas [110]

Answer:

The percentage of mass recover from recrystallization = 24.69 %

Explanation:

Given that

Initial mass of crude acetanilide = 166 gm

The mass after recrystallization = 125 gm

The mass recover from recrystallization= 166 - 125 gm

The mass recover from recrystallization= 41 gm

The percentage of mass recover from recrystallization can be find as

$percentage\ of\ mass\ recover\ from\ recrystallization\ =\dfrac{166-125}{166}$

The percentage of mass recover from recrystallization = 24.69 %
