for an object that is speeding up in the positive direction, what does the displacement vs. time graph look like?
slava [35]

Answer:

The speeding up is steady, it is a parabola (a=V*t+(at^2)/2), and give it's an equation in connection to time, at that point, it is conceivable to discover the separation recipe by utilizing more substantial amount mathematics(integrals).

2. Anna mixes 200 g of hot coffee at 90 °C with 50 g of cold water at 3 °C to bring down the temperature of the coffee. Explain
natka813 [3]

The average kinetic energy of the molecules of the coffee will decrease and the speed of the individual molecules will also reduce.

<h3>Temperature of resultant mixture</h3>

The temperature of the resultant mixture will be higher than the cold water temperature and lower than the hot coffee temperature.

Based on the decrease of the resulting temperature (equilibrium temperature) of the mixture, the average kinetic energy of the molecules of the coffee will decrease and the speed of the individual molecules of the hot coffee mixture will reduce, leading to a resultant cold mixture of coffee.

Which of the following statements incorrectly describes a scenario where the source of the sound waves and the person hearing th
iris [78.8K]
The answer to this question is C.  The reason why this is an incorrect statement is that the Doppler effect takes into account two moving objects.  In this scenario, both the source and the listener are stationary to the frequency of the sound waves will not change due to the Doppler effect.  For the other answers, the frequency of sound waves is not affected by nature of the medium.  The distance between a sound source and listener does not alter the frequency of the sound wave.  The frequency of the sounds waves remains the same to the listener.
