if the radius of the capillary tube is doubled, what changes will take place in the hieght of rise of liquid with capacity tube
tangare [24]

Explanation:

The height of the rise of liquid with capillary tube is given by the formula as follows :

h=\dfrac{2S\cos\theta}{r\rho g}

Where

r is radius

It is clear that the height of the rise of liquid is inversely proportional to the radius of the capillary tube.

If the radius of the capillary tube is doubled, it means the height of rise of liquid with capillary tube become half.

A lumberjack (mass = 110 kg) is standing at rest on one end of a floating log (mass = 206 kg) that is also at rest. The lumberja
Lemur [1.5K]

Answer:

a). The velocity of the first log is -1.65 m/s.

(b). The velocity of the second log is 1.07 m/s.

Explanation:

Given that,

Mass of lumberjack M= 110 kg

Mass of log m= 206 kg

Final velocity = 3.09 m/s

(a). We need to calculate the velocity of the first log just before the lumberjack jumps off

Using conservation of momentum

Mu_{1}+mu_{2}=Mv_{1}+mv

Put the value into the formula

0=110\times3.09+206v

v=-\dfrac{110\times3.09}{206}

v=-1.65\ m/s

The velocity of the first log is -1.65 m/s.

(b). If the lumberjack comes to rest relative to the second log

We need to calculate the velocity of the second log

(M+m)v=Mv_{1}

v=\dfrac{Mv_{1}}{M+m}

Put the value into the formula

v=\dfrac{110\times3.09}{110+206}

v=1.07\ m/s

The velocity of the second log is 1.07 m/s.

Hence, (a). The velocity of the first log is -1.65 m/s.

(b). The velocity of the second log is 1.07 m/s.
