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

Un corredor hace los 400 metros lisos en 50 seg. Calcula la velocidad en la carrera.
RoseWind [281]

Answer:

8 meters/second

Explanation:

Rate x Time = Distance

R x T = D

R x 50sec = 400meters

R x 50sec/50sec = 400meters/50sec

R = 8meters/sec

4.7 cm. The tube is sealed at one end and loaded with lead shot to give it a total mass of M = 130 g. The tube floats in water (
babunello [35]

Answer:

Depth is 7.49cm

Explanation:

Given that;

The diameter of tube is (D)=4.7cm

Area of the tube is =πD^2/4

Area is 3.142*4.7*4.7/4=17.35cm2

Mass(M)=130g

Density =1g/cm^3

Recall that Density =mass /volume

Hence volume =130/1=130cm^3

Also note

Volume=area*depth

130=17.35*depth

Depth=130/17.35=7.49cm

What affect, if any, does increasing the speed of the plunger have on the wavelength of the waves
mojhsa [17]

As the speed of the plunger increases, the wavelength of the waves decreases. The greater the frequency, the smaller the wavelength. The smaller the frequency, the greater the wavelength. When we increase the speed of the plunger, the frequency of the waves also increases, and just like with the size of the ball, it’s the speed of the plunger and the frequency of the waves are directly related.
