A table tennis ball with a mass of 0. 003 kg and a soccer ball with a mass of 0. 43 kg are both set in motion at 16 m/s. Calculate and compare the momenta of both balls.
Answer:
0.048 kgm/s, 6.88 kgm/s
Explanation:
m = 0.003 kg, M = 0.43 kg, v = 16 m/s
The momentum of a table tennis ball = mv = 0.003 * 16 = 0.048 kgm/s
The momentum of a soccer ball = Mv = 0.43 * 16 = 6.88 kgm/s
The two balls have same speed, but different masses. A table tennis ball has smaller mass, so the momentum is smaller too.

For what value of k, if any, is y=e−2x+ke4x a solution to the differential equation y−y′′4=5e4x ?
Applying substitution, it is found that y is a solution to the differential equation for k = 1.
What is the differential equation:It is given by:
[tex]y - \frac{y^{\prime\prime}}{4} = 5e^{4x}[/tex]
We are testing the following solution:
[tex]y = e^{-2x} + ke^{4x}[/tex]
It's derivatives are given by:
[tex]y^{\prime}(x) = -2e^{-2x} + 4ke^{4x}[/tex]
[tex]y^{\prime\prime}(x) = 4e^{-2x} + 16ke^{4x}[/tex]
Then, replacing in the differential equation:
[tex]y - \frac{y^{\prime\prime}}{4} = 5e^{4x}[/tex]
[tex]e^{-2x} + ke^{4x} - \frac{4e^{-2x} + 16ke^{4x}}{4} = 5e^{4x}[/tex]
[tex]e^{-2x} + ke^{4x} - e^{-2x} + 4ke^{4x} = 5e^{4x}[/tex]
[tex]5ke^{4x} = 5e^{4x}[/tex]
[tex]5k = 5[/tex]
[tex]k = 1[/tex]
Then, y is a solution to the differential equation for k = 1.

Answer:
-5/3
Explanation:
Correct. One way to verify that a function is a solution to a differential equation is to check that the function and its derivatives satisfy the differential equation. The differential equation in this problem involves both y
and y′′
.
y=e^−2x + ke^4x y′ =−2e^−2x + 4ke^4x y′′= 4e−2x+16ke^4x
Then y−y′′4=e^−2x+ke^4x−(4e−2x+16ke^4x)4=−3ke^4x
.
If −3ke4=5e4x
, then −3k=5⇒k=−53
.
Therefore, y=e−2x+ke4x
will be a solution to the differential equation if k=−5/3

We have two containers with an identical amount of gas in each. One gas is helium, the other is ammonia. Which would you expect to have the higher pressure?
The gas with a higher pressure is Helium
Calculating the pressure exerted by the gasesGiven that temperature and volume is held constant the pressure of a given gas can be calculated as : P = n because for a constant volume and temperature the pressure of a given gas is directly proportional to the number of moles of contained in the gas.
Pressure of Helium
P = n
where n ( number of moles ) = mass of helium / molar mass
= 52 / 4 = 13 moles
Pressure of Ammonia
P = n
where n ( number of moles ) = mass / molar mass of ammonia
= 73 / 17.03
= 4.29 moles
From the calculations above the gas with a higher pressure is Helium.
