(.140*25)+(75*0)= 3.5

3.5 = (.140 + 75)v

(3.5)/(.140 + 75) = v = .04657

which rounds up to .05 m/s

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.

MArishka [77]

Complete Question:

Suppose that an asteroid traveling straight toward the center of the earth were to collide with our planet at the equator and bury itself just below the surface. What would have to be the mass of this asteroid, in terms of the earth’s mass M, for the day to become 25.0% longer than it presently is as a result of the collision? Assume that the asteroid is very small compared to the earth and that the earth is uniform throughout.

Answer:

m = 0.001 M

Determine the change in internal energy of a monatomic ideal gas that expands from an initial volume of 1.53 m3 to a final volum
Illusion [34]

Answer:

Internal energy will be 2.05\times 10^5Joule

Explanation:

We have given that initial volume v_1=1.53m^3

And final volume v_2=2.87m^3

Pressure p=1.02\times 10^5Pa

Now change in volume dv=2.87-1.53=1.34m^3

We know that change in internal energy is given by

\Delta U=\frac{3}{2}nR\Delta T, here we know that

Work done W=Pdv=nR\Delta T

So \Delta U=\frac{3}{2}PdV=\frac{3}{2}\times 1.02\times 10^5\times 1.34=2.05\times 10^5Joule
