Describe how work done is related to a change in volume of a fluid. 100 points
Answer: work is the pressure acting through the change in volume
Explanation:
In the same way that work is defined as force operating over a distance, work is the pressure acting through the change in volume. Pressure is comparable to force in pressure–volume work, while volume is analogous to distance in the classic definition of work.
Just as we say that work force acting over a distance,for fluids,we can say that work is the pressure acting through the change in volume. for pressure- volume work, pressure is analogous to force, and the traditional defination of work.
One evening, a student tells her sister that the Sun only appears brighter than other stars because the Sun and stars are different distances from Earth. Her sister disagrees, so the student supports her argument by asking her sister to observe the brightness of streetlights throughout their neighborhood. Which observation would support the student’s argument?
Comparing and analyzing the brightness of near and farther streetlight would support the student’s argument.
Which observation would support the student’s argument?The brightness of nearer streetlight is more as compared to the brightness of the farther light because brightness decreases with the increase in distance.
So we can conclude that comparing and analyzing the brightness of near and farther streetlight would support the student’s argument.

Prove that force canbe defined as rate of change in momentum
The force can be defined as rate of change in momentum because consists of the action of rotating or twisting a body around its axis of rotation (pole) through the application of a force.
What is the difference between moment and force?The magnitude of the moment (M) is defined as the product of the magnitude of the force (F) and the distance (d) between the line of action of the force and the axis. The unit of moment of a force in the international system of units is N.m.
Torque, or moment of a force, is the tendency of a force to rotate a body on which it is applied. Torque is a vector perpendicular to the plane formed by the force and radius of rotation vectors.

What can you say about the effort force needed to lift an object using an ideal lever with a force advantage greater than 1?
Select one:
a. The effort force is the same as the lifting force.
b. The effort force is less than the lifting force.
c. The effort force is greater than the lifting force.
d. You have to use the formula to calculate the effort force.
When the effort force needed to lift an object using an ideal lever with a force advantage greater than 1, The effort force is less than the lifting force. The correct option is b.
What is force advantage?Force is the mechanical physical quantity. The force advantage is equivalent to the mechanical advantage equal to the ratio of output to the input force.
The force advantage is
F.A = lifting force / effort force
When the effort force is greater, FA is less than 1. When FA is greater than 1, definitely, the effort force is less.
Thus, the effort force is less than the lifting force. The correct option is b.

What is the role of pressure and dissolved gases in eruptions?.
Answer:
Explanation:
Magma contains dissolved gases, which provide the driving force that causes most volcanic eruptions. As magma rises towards the surface and pressure decreases, gases are released from the liquid portion of the magma (melt) and continue to travel upward, and are eventually released into the atmosphere.

Drag force on a body increase with the increase in speed of the body.justify with one example from everyday experience
The drag force is the force that opposes the movement of a body through a fluid.
What is the drag force?The drag force is the force that opposes the movement of a body through a fluid. This occurs in cases such as when a car is moving through air.
Owing to the fact that drag force tends to slow down vehicles when they move at higher speed, vehicles that are meant for racing are streamlined to reduce the drag force.

Medium and heavy duty vehicles often require increased braking in situations where friction brakes overheat and fail. This can be addressed by using a(n):
Medium and heavy duty vehicles require a better braking option hence they ought to have an exhaust brake.
What is a brake?A brake is used to slow down or stop an automobile. When the brake is applied, the speed of the automobile continues to decrease until it comes to a complete halt.
Friction brakes are apt for light vehicles that may not have the tendency to overheat. However, heavy duty vehicles may overheat often and do require an exhaust brake.The exhaust brake is most fitted for heavy duty vehicles and diesel engines.

Does this equation show that transmutation has taken place during decay?
Why or why not?
6128 Ni -> 6128 Ni + y
A. Yes, because the numbers of nucleons and atoms are conserved.
B. No, because there is conservation of the number of atoms as well as the number of nucleons.
C. Yes, because the nickel atoms remain nickel atoms with the same number of neutrons.
D. No, because high-energy electromagnetic waves are emitted.
Explanation:
Transmutation means change in neutron numbers u
Like for example
When Potassium (N=19 ) goes through beta decay it forms (N=20)
Here no change in neutrons (Same 28)
So no trnasmutaions.

a.5 kg model rocket launches with a thrust of 5 n in the upward direction. can it lift off of the ground? (hint: gravity is pulling it toward
the earth at 9.8 m/s2) (f=mx a) assume there is no wind resistance.
Answer:
F = F2 - F1 where F is the net force upwards
F = 5 - (.5 * 9.8) = (5 - 4.9) N = .1 N
Since there is a net force in the upwards direction the rocket should experience an upwards acceleration.

What is the wavelength of an infrared wave with a frequency of 4.0E14 Hz.
Answer:
f λ = c = 3.00E8 frequency * wavelength = speed of light
λ = c / f = 3.00E8 / 4.0E14 = 7.5E-7 m
Note 1 angstrom = 1.00E-10 m and 1 milli-micron = 1.00E-9 m
So the wavelength would be 7500 angstroms
The visible spectrum is 4000 A - 7000 A or 400 - 700 milli-microns
This diagram shows a hydrogen atom. Explain why it looks
like it does
Make-up of Hydrogen
Hydrogen atoms are extremely simple. They are the first atom on the periodic table, this means that they only have 1 proton. The majority of hydrogen atoms don't even have a neutron. As for electrons, hydrogen atoms with no charge have 1 electron. All of this means that for almost all hydrogen atoms the nucleus is made of one singular proton.
Diagram
The diagram shows a hydrogen atom. It looks like one circle because it is just showing the singular proton found in the nucleus. Electrons are extremely small compared to protons, so the electron is not shown in the picture. It is very hard to accurately depict electrons on diagrams like this because of their size and the fact that we can never know where they are. So, the diagram may look too simple but it just depicts how most hydrogen nuclei look.
Answer: It only has 1 proton.
a table tennis ball launcher fires a tennis ball. what do we know about the impulse on both of the objects?
Answer:
As we know by Newton's III law that if an action force is applied on an object then the reaction force of same magnitude in opposite direction will act on the other.
So here when ball is shot using launcher then the force will be same on launcher as well as ball so we can say
now since force is of same magnitude for both both then we will have
so from above we can say that both ball and launcher will have same impulse but opposite in direction.
Now since ball will have less mass so here it will have more speed while launcher is heavy in mass so its speed is slow or very small as comapre to ball.
