How does is the terminal velocity of a feather different from the terminal velocity of an egg?
Answers
Answer:
The terminal velocities will be the same in a vacuum and different for the egg and further.
Explanation:
Thinking process:
The terminal velocity is the maximum velocity that an object can attain after overcoming the resistance caused by the atmosphere or air. In other words, the velocity equation is given as:
where F is the net force,
D = Drag force
W = Weight of the object falling down.
The drag force increases by the increase with the square of the velocity like this:
The terminal velocity is given by the equation:
V = Sqrt (2W/CdpA)
In the absence of friction, like a vacuum, the velocities are the same.
In the atmosphere, there is drag, and the velocities are different.

It is impossible to determine the exact position and momentum of electron simultaneously. Therefore, option B is the correct answer.
According to Heisenberg’s uncertainty principle,it is impossible to determine simultaneously, the exact position and momentum of an electron.
Mathematical expression
ΔX.ΔP ≥ h/4π
ΔX = uncertainty in position
ΔP = uncertainty in momentum
h = Plank’s constant
π= Pi
Thus, we can conclude its nearly impossible to determine electron’s exact position. Therefore, option B is the correct answer.

Answer: Kepler
Explanation:
At the time when general masses believed in the geocentric model of universe where Earth is the center of the universe. Tycho Brahe was a Danish noble man. Kepler was the student of Tycho Brahe. Kepler firmly believed that Sun was the center of the universe. The extensive data records collected by Brahe eventually helped his student Kepler to formulate laws that defined orbits of the planet. Their work contributed to confirm heliocentric model.

Explanation:
Start with the ideal gas law:
PV = nRT
Rearranging:
P/T = nR/V
Since the right side is constant (volume and mass don't change):
P₁ / T₁ = P₂ / T₂
This equation is also known as Gay-Lussac's law. Plugging in the values (make sure to use absolute pressure and temperature):
(32 psi + 14.7 psi) / (25 + 273.15) K = (36 psi + 14.7 psi) / T
Solving for T:
T = 323.69 K
T = 50.5°C
