An air bubble at the bottom of a lake 52.0 m deep has a volume of 1.50m^3. If the temperature at the bottom is 5.5 degree's Cels

ius and at the top is 18.5 degree's Celsius, what is the volume of the bubble just before it reaches the surface?

Answer:

The volume of the bubble near the surface will be 9.47 m³

Explanation:

Given that,

Depth = 52.0 m

Volume = 1.50 m³

Temperature at bottom = 5.5°C

Temperature at the top = 18.5°C

We need to calculate the pressure at the depth 52.0 m

The pressure is

P_{1}=P_{2}+\rho gh

Where, P_{2} = Pressure at the surface

P_{1} = Pressure at the depth

Put the value into the formula

P_{1}=101325+(1000\times9.8\times52.0)

P_{1}=610925\ N/m^2

We need to calculate the volume of the bubble just before it reaches the surface

Using equation of ideal gas

PV=RT

\dfrac{PV}{T}=constant

Now, The equation of at bottom and top

\dfrac{P_{1}V_{1}}{T_{1}}=\dfrac{P_{2}V_{2}}{T_{2}}

V_{2}=\dfrac{P_{1}V_{1}T_{2}}{P_{2}T_{1}}

Put the value into the formula

V_{2}=\dfrac{610925\times1.50\times(18.5+273)}{101325\times(5.5+273)}

V=9.47\ m^3

Hence, The volume of the bubble near the surface will be 9.47 m³

Explain, briefly, what the electrical field inside a microwave oven does to heat food.
yarga [219]

Answer:

Inside the strong metal box, there is a microwave generator called a magnetron. When you start cooking, the magnetron takes electricity from the power outlet and converts it into high-powered, 12cm (4.7 inch) radio waves. Thus the microwaves pass their energy onto the molecules in the food, rapidly heating it up.May 3, 2018

a spring with a constant of 80N/m is stretched by a force of 240N. how much the displacement of the spring from equilibrium?
Inessa05 [86]

Answer:

1200N/m

Explanation:

given parameters:

force on the motorcycle spring is 240N

Extension 2cm or 0.02m

unknown _

spring constant:

:?

solution:

to a spring a force applied is given as :

f=ke

f is applied as force

k is spring constant

e is the Extension

240= kx0.02

k=1200N/m
