Answer:

1. OK the

1. The horizontal axis of a osclloscope is generally TIME axis.

2. given T =25 micro second

That is = 25E-6 s

Then We f = (1/T) .

So f = 1/(25 x 10^-6) = 40000 Hz =

40 KHz.

3. First Band will be Yellow

Second Band will be Violet

Third Band will be Red

And

Fourth Band will be Gold

Thus, the value of the resistance = (47 x 100)plus or minus 5%

= (4700 plus or minua5%) ohm

the range of the acceptable value of the resistance will now be

= 4465 ohm to 4935 ohm

(4)

The level provided by the wall outlet = 120 x √2 = 169.68 V

The √2 is because the multimeter measures RMS voltage rather than peak voltage and

RMS Voltage is = √2 x peak voltage

At 80 degrees celsius the vapor pressure of benzene is 753 torr and that of toluene is 290 torr. What is the total pressure and

nexus9112 [7]

Answer:

The total pressure of the solution is 598.66 torr

while the vapor pressure of the components is vapor pressure of benzene is =502 torr and that of toluene = 96.6 tor

Explanation:

To solve this question, we need to look at the known variables, the unknown variables, and then we select the appropriate relations between the known variables and the unknown

Here we have the temperature of the gases t = 80°C

the pressures of benzene = 753 torr

the pressures of toluene = 290 torr

mole fraction of benzene in solution = 2/3

mole fraction of toluene in solution = 1/3

the unknown variables = composition of the solution and the total pressure of the solution

From here given the known variables and the required variables, the appropriate relation bstween the known and unknown variables is Route's Law

Raoult's relates the vapor pressure of a mixture of gases to the mole fraction of solute gases introduced in the gas solution. Raoult's Law is expressed by the formula: Psolution = Χsolvent1×Psolvent1 + Χsolvent2×Psolvent2+ ... .

where. Psolution = vapor pressure of the solution and

Χsolvent1 = mole fraction of solvent 1

Psolvent1 = vapor pressure of solvent1

Thus we have by Raoult's Law

$P_{solution}$ = $X_{benzene}$ × $P_{benzene}$ + $X_{toluene}$ × $P_{toluene}$

which is =2/3×753 + 1/3×290 = 502 + 96.6 = 598.66 torr

and composition vapor pressure of benzene is 502 torr

while the composition vapor pressure of toluene is 96.6 torr

At what distance of separation, r, must two 3.20 x 10-9 Coulomb charges be positioned in order for the repulsive force between t

STatiana [176]

I'm not 100% sure but I think the answer is 60.4, because you multiply 3.20 by 10, to get 32 - 9 = 23, then subtract 23 from 83.4. Hope this helps you, and good luck!!!

Which of the following changes would make a heat engine less efficient

DIA [1.3K]

A heat engine would be less efficient due to many factors
For instance, a heat engine is more efficient when it uses in cold weather because there is a greater temperature difference ( Carnot Efficient )
A heat engine could be less efficient because of friction
