A gaseous refrigerant undergoes compression when 150 j of work is done on it. if the internal energy of the gas increases by 120

zhenek [66]

The heat transferred is -30J

When the gas undergoes compression, work is done on the gas and its internal energy increases.

According to the first law of thermodynamics, the increase in internal energyΔU is the sum of the heat given to the gas ΔQ and the amount of work done on the gas ΔW

$\Delta U=\Delta Q +\Delta W$

The work done on the gas is 150 J due to compression and the internal energy of the gas increases by 120 J.

Therefore, the heat given to the gas is given by,

$\Delta Q =\Delta U -\Delta W\\ =120 J -150 J\\ =-30 J$

Thus, an amount of heat equal to 30 J flows out of the system.

German physicist Werner Heisenberg related the uncertainty of an object's position (Δx) to the uncertainty in its velocity (Δ???

fredd [130]

Answer:

$\Delta x = 5.47 \times 10^{-9} m$

Explanation:

As we know by the principle of uncertainty that the product of uncertainty in position and uncertainty in momentum is given as

$\Delta x \times \Delta P = \frac{h}{4\pi}$

so here we know that

$\Delta v = 0.01 \times 10^6 m/s$

$m = 9.11 \times 10^{-31} kg$

so we have

$\Delta x \times (9.11 \times 10^{-31})(0.01 \times 10^6) = \frac{6.26 \times 10^{-34}}{4\pi}$

$\Delta x = 5.47 \times 10^{-9} m$

Which letter represents the position of maximum potential energy of the pendulum

worty [1.4K]

If you mean the SI Unit of GPE, the answer is J for Joules.
if that's not the question being asked, i would need a little more elaboration please :)
