Answer:

propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.

3) If an electrical appliance has 150.0 V applied causing a current of 2.34 amps, what is the

eimsori [14]

The resistance of the appliance is 64.1 Ω.

<u>Explanation:</u>

As per the Ohm's law, which states that the electric current is in direct proportion to the voltage and is in inverse proportion to the resistance. It is given by the expression as,

V = IR

Where V is the voltage (V) = 150.0 V

I is the current (amps) = 2.34 amps

R is the resistance (ohm) or Ω = ?

Now we have to rearrange the equation to get the resistance as,

$$R = \frac{V}{I}$

Now we have to plug in the values as,

$$ R = \frac{150}{2.34}$

= 64.1 Ω

So the resistance of the appliance is 64.1 Ω.

If a sample of gas has a volume of 100.0ml when the pressure is 50.0kPa, what is volume when the pressure is increased to 400.0k

dalvyx [7]

Answer:

V₂ = 12.5 mL

Explanation:

Given data:

Initial volume = 100.0 mL

Initial pressure = 50.0 KPa

Final volume = ?

Final pressure = 400.0 KPa

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume

Now we will put the values in formula,

P₁V₁ = P₂V₂

50.0 KPa × 100.0 mL = 400 KPa × V₂

V₂ = 5000 KPa.mL/ 400 KPa

V₂ = 12.5 mL

Convert 732.0 mmHg to atm

enot [183]

Answer:

The answer is

Explanation:

To solve the question we use the following conversion

That's

1 mmHg $\cong$ 0.0013 atm

So we have

If 1 mmHg $\cong$ 0.0013 atm

Then 732 mmHg will be

732 × 0.0013 atm

We have the final answer as

Hope this helps you
