Work is being done in which of these situations? All motions are at a constant velocity (including velocity = zero).
tigry1 [53]

Answer:

None of the above

Explanation:

Work is defined as the force that moves an object through a particular distance:

    Workdone = force x displacement

At constant velocity, the force on a body is zero because such a body is not accelerating.  

    Force is a product of mass and acceleration. Acceleration occurs only when velocity changes with time. If no change in velocity, acceleration does not occur. Therefore, no force is being applied.

 From all the situations given, the condition is set at constant velocity. At constant velocity, there is no acceleration. This implies that no work is done.

How many moles of CO2 are there in 2.55 x 10<br><br> 18<br><br> molecules of CO2?
cluponka [151]

Answer: There are 4.23\times 10^{-6}moles  of CO_2

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadros number}}

\text{Number of moles}=\frac{2.55\times 10^{18}}{6.023\times 10^{23}}=0.423\times 10^{-5}moles

Thus there are 4.23\times 10^{-6}moles  of CO_2
