What happens to the pwc when the throttle is released?
Sergio [31]
PWC operators must keep in mind that a jet drive needs moving water through the drive nozzle for maneuverability. In other term, you must have power applied in order to uphold steering control. If the engine shuts off during operation or If you release the throttle to idle, you will lose all steering control. In either situation, the PWC will remain in the direction it was headed before the throttle was released or the engine was shut off. Action of the steering control will have no outcome. If you are approaching a dock, shore, or other vessel at a speed bigger than you can control and you release the throttle to idle or shut off the engine, you won’t have maneuvering capability and the PWC will stay its forward movement.

Calculate the pressure exerted by 11.1 moles of neon gas in a volume of 5.45 L at 25°C using (a) the ideal gas equation and (b)
Ilia_Sergeevich [38]

Answer:

49.82414 atm

50.74675 atm

Explanation:

P = Pressure

V = Volume = 5.45 L

R = Gas constant = 0.08205 L atm/mol K

T = Temperature = 25°C

a = 0.211 atm L²/mol²

b = 0.0171 atm L²/mol²

From ideal gas law we have

PV=nRT\\\Rightarrow P=\dfrac{nRT}{V}\\\Rightarrow P=\dfrac{11.1\times 0.08205(273.15+25)}{5.45}\\\Rightarrow P=49.82414\ atm

The pressure is 49.82414 atm

From Van der Waals equation we have

\left(P+\frac{an^2}{V^2}\right)\left(v-nb\right)=nRT\\\Rightarrow P=\dfrac{nRT}{V-nb}-\dfrac{an^2}{V^2}\\\Rightarrow P=\dfrac{11.1\times 0.08205\times (273.15+25)}{5.45-(11.1\times 0.0171)}-\dfrac{0.211\times 11.1^2}{5.45^2}\\\Rightarrow P=50.74675\ atm

The pressure is 50.74675 atm

A puddle of water has a thin film of gasoline floating on it. A beam of light is shining perpendicular on the film. If the wavel
g100num [7]

Answer:

option A

Explanation:

Given,

wavelength of light,\lambda = 560\ nm

refractive index of gasoline, n₁ = 1.40

Refractive index of water, n₂ = 1.33

thickness of the film, t = ?

Condition of constructive interference is given by

2 n t = (m+\dfrac{1}{2})\lambda

For minimum thickness of the film m = 0

From the question we can clearly observe that phase change from gasoline to air

so, n = 1.4

2 \times 1.4 \times t = \dfrac{560}{2}

t = 100\ nm

Hence, the correct answer is option A

Rank the band gap energies of the following solids. Metal insulator semiconductor superconductor I. large band gap energy II. sm
Anon25 [30]

Answer:

Metal - smallest band gap energy

insulators -  large band gap energies

semiconductor -  Band gap of intermediate energies

superconductor cooper pair theory is applied for calculating gap energies.

Explanation:

Metal - smallest band gap energy

it is due to the fact that valence and conduction bond in metal are in overlapped conditioned. Therefore showing zero gap energies

insulators -  large band gap energies

insulator has high band gap

semiconductor -  Band gap of intermediate energies

semi conductor has gap of intermediate range

while for superconductor cooper pair theory is applied for calculating gap energies.
