An equilibrium constant is not changed by a change in pressure
a. True
b. False

Answers

Answer 1
Answer:

Answer:True

Explanation:In an ideal situation, equilibrium constants cannot be altered if you change the pressure of a system. However, only change in temperature can result to change in equilibrium constants. If there are the same value of molecules on either side of the equation, then a change of pressure is insignificant to the position of equilibrium.

How to find the time in the air based off of the height and velocity

Answers

Answer:

To find time to reach maximum height given initial velocity use the equation Vf=vi+at. At the maximum height, the object has no initial velocity left and therefore you can substitute 0 for the Vf in the equation.

How does is the terminal velocity of a feather different from the terminal velocity of an egg?

Answers

if under vacuum the terminal velocity of the egg and feather would be the same because only the acceleration due to gravity is only force acting on it. but at normal condition, their terminal velocity are different because to wind resistance and shape factor that will contribute resistance of an object to go down.

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:

F_(net) = D -W

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:

W = C_(d) \frac{\rhoV^(2)A } {2}

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.

a skier is gliding along 3.0 m/s on horizontal, frictionless snow. he suddenly starts down a 10 degrees incline. his speed at the bottom is 15 m/s. what is the lenght of the incline? how long does it take him to reach the bottom?

Answers

... find length
(way 1) determine acceleration using force
only force act on skier is mg vertically. spilt vector we get force along the incline = mgsin(10) and f= ma so
ma = mgsin(10) or a = gsin(10)
a (along the incline)= gsin(10) = 10sin(10) = 1.74
v^2 = u^2 + 2as
15^2 = 3^2 + 2(1.74)s
s = 62.06 m

(way 2) using conservation of energy
energy (KE+PE) on top = energy at bottom
0.5m3^2 + mgh = 0.5m15^2 +0
h (height of incline) = (112.5 - 4.5)/10 = 19.8 m
length of incline = h/sin(10) = 62.2 m ; trigonometry

... find time
s = (u+v)t/2
t = 2s/(u+v) = 2(62.2)/(3+15) = 6.91 s

Answer;

Speed up small particles

Explanation;

  • A particle accelerator is a machine that accelerates the sub-atomic particles such as electrons or protons to high energies. The particle accelerators produce beams of charged particles which may used for different research purposes.
  • The accelerators propel charged particles to speed near the speed of light and colliding them using electromagnetic fields, which allows scientist to use them in research.

Which of the following actions or events did not contribute to the Dust Bowl? Farmers in the Central U.S. had plowed grasslands to grow food crops to feed the increasing human population. They left the fields plowed and bare in the winter months when crops were not grown, and this left the soil exposed to wind. A long drought in the 1930s left the exposed soil especially dry due to the lack of precipitation. With the advent of pesticides, minerals in the ground were leached.
