When the temperature of 2.35 m^3 of a liquid is increased by 48.5 degrees Celsius, it expands by 0.0920 m^3. What is its coeffic
Nuetrik [128]

Answer:

8.1\cdot 10^{-4} C^{-1}

Explanation:

The volumetric expansion of the liquid is given by

\Delta V=\alpha V_0 \Delta T

where

\alpha is the coefficient of volume expansion

V_0 is the initial volume

\Delta T is the change in temperature

For the liquid in this problem,

V_0 = 2.35 m^3\\\Delta T=48.5^{\circ}C\\\Delta V=0.0920 m^3

So we can solve the equation to find \alpha:

\alpha=\frac{\Delta V}{V_0 \Delta T}=\frac{(0.0920 m^3)}{(2.35 m^3)(48.5^{\circ}C)}=8.1\cdot 10^{-4} C^{-1}

Does orbital direction of a planet affect its synodic period as seen from earth?
Mice21 [21]

Answer:

Yes

Explanation:

Yes, the orbital direction of a planet affect its Synodic period as seen from earth. The synodic period of mercury is about 116 days on Earth. Whereas the sidereal period of mercury as seen from Earth is 88 days.  This difference is caused by the simultaneous motion of Earth in its orbit. Hence we can say that the  orbital direction of a planet affect its synodic period as seen from earth.
