The change in the kinetic energy of the system from when it is released to the instant it hits the ground is most nearly; (My + Mx)gH
We are told that the two objects X and Y are held together by a light string.
Their masses are;
Mass of Object X = Mx
Mass of objetc Y = My
Since the two objects are released from rest, it means we need to find potential energy and the formula for potential energy is;
P.E = mgh
Now, since both objects are released from rest and since My is larger than Mx, it means that potential energy is now;
ΔP.E = (My + Mx)gH
Now, according to conservation of energy,
Change in kinetic energy = Change in potential energy.
Thus;
Change in kinetic energy = (My + Mx)gH

An elevator in a hotel starts at ground level. It rapidly moves up to the third floor, where it stops to unload passengers. The elevator then descends to the basement at a slower speed than before.
The graph correctly represents the story illustrated in the graph.
From the given graph, from the ground floor to the third floor is a rapid acceleration.
During the unload at the third floor, the velocity was constant until all the passengers was unloaded.
The deceleration of the elevator was slower than the acceleration because it occurred at a longer time.
Thus, we can conclude that the graph correctly represents the story illustrated in the graph.

You have 41. 6 g of o2 gas in a container with twice the volume as one with co2 gas. The pressure and temperature of both containers are the same. Calculate the mass of carbon dioxide gas you have in the container.
Answer: The mass of carbon dioxide is 28.6 grams
Explanation: Step 1: Data given
Mass of O2 = 41.6 grams
Volume of the O2 container = 2V
Volume of the CO2 container = V
Pressure and temperature are the same
Step 2: Ideal gas law
The ideal gas law = p*V=nRT
For O2: p*2V = n(O2)*R*T
For CO2: p*V = n(CO2)*R*T
n(O2)*R*T / P*2V = n(CO2)*R*T / P*V
Since P, R and T are contstant, we can simplify this to:
n(O2)/2 = n(CO2)
Step 3: Calculate moles of O2
Moles O2 = mass O2/ Molar mass O2
Moles O2 = 41.6 grams / 32 g/mol
Moles O2 = 1.3 mol O2
The number of moles CO2 = 0.65 mol
Mass of CO2 = Moles CO2 * Molar Mass CO2
Mass of CO2 = 0.65 mol * 44.01 g/mol
Mass of CO2 = 28.6 grams
The mass of carbon dioxide is 28.6 grams
