Name two examples of deposition.

Rashid [163]

The reverse of deposition is sublimation and hence sometimes deposition is called desublimation. One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid.

LuLu mixes a solution of vinegar for a homemade salad dressing she is making. She makes 300 mL of vinegar by mixing 135 mL aceti

photoshop1234 [79]

Answer:

percentage by volume of the solute = 45%

Explanation:

The percentage by volume of the solute in a solution is the percentage of the volume of the solute as against the overall volume of the solution.

In this example,

volume of solution = 300mL

volume of solute = 135mL

% volume of solute = (volume of solute ÷ volume of solution) × 100

= (135 ÷ 300) × 100

= 0.45 × 100 = 45%

∴ percentage by volume of the solute = 45%

What is the value of the charge that experiences a force of 2.4 Ã— 10â€“3 n in an electric field of 6.8 Ã— 10â€“5 n/c?

tia_tia [17]

Answer:

The value of charge is 35.3 C

Explanation:

Given:

Force $F = 2.4 \times 10^{-3}$ N

Electric field $E = 6.8 \times 10^{-5} \frac{N}{C}$

According coulomb's law,

$F = qE$

Where $q =$ charge that experience a force,

For finding the value of charge,

$q = \frac{F}{E}$

$q = \frac{2.4 \times 10^{-3} }{6.8 \times 10^{-5} }$

$q = 35.3$ C

Therefore, the value of charge is 35.3 C

The garcias like to keep their 40.0 watts front prch light on at night to welcome visitors. if the light is on from 6pm until 7a

Gnesinka [82]

Answer:

For 1 week total cost will be equal to 0.2912

Explanation:

We have given power P = 40 watt

Light is on from 6 pm to 7 am

So total time = 13 hours

We know that energy is given by

$Energy=power\times time$

So energy will be $E=40\times 13=520watt-hour=0.520Kwh$

We have given cost per KWh is 0.08

So total cost per day will be = 0.08 ×0.520 = 0.0416

For 1 week that is for 7 day total cost will be = 7×0.0416 = 0.2912
