Question 1: Charge is also said to be conserved. What does it mean? Explain.
Answer:

The principal that net electric charge is neither created nor destroyed but is transferable from one material to another.

So the Charge is also said to be conserved.

Charge conservation is a physical law that states that the change in the amount of electric charge in any volume of space is exactly equal to the amount of charge flowing into the volume minus the amount of charge flowing out of the volume. In essence, charge conservation is an accounting relationship between the amount of charge in a region and the flow of charge into and out of that

region.

Mathematically, we can state the law as a continuity equation:

Question 3: If a charged particle moves in a straight line through some region of space, can you say that the magnetic field in that region is zero?
Answer:
If the charged particle is moving along the magnetic field -- parallel or antiparallel to the magnetic field -- then there would be no force on it.
Question 4: If you know the position vectors of a particle at two points along its path and also know the time it took to move from one point to the other, can you determine the particle's instantaneous velocity its average velocity. Explain
Answer:

Lets suppose r1 and r2 are the two position vectors of a particle and it takes time To move from one point to the other then the instantaneous velocity can be find

By d=r2-r1 the instantaneous velocity

V(ins)=lim (delt'0)(del d)/(del t)

V(avg)=del v/del t

Question 5: In an analogy between electric current and automobile traffic flow, what would correspond to charge. What would correspond to current?
Answer:
Consider all of the lanes in one direction on a highway, taken together. Then, individual vehicles correspond to bits of charge. The number of vehicles that pass some designated milepost, divided by the time during which they go past, corresponds to the value of the current.
Question 6: Steel will rapture if subjected to a shear stress of more that about 4.2 * 108 N/m2. What sideward force is necessary to shear a steel bolt 1 cm in diameter?
Answer:
Converting 1 cm to meter =.01m
Shearing stress =F/A
And all 1 to 22 chapters formulas in easy format.
Shearing stress*A=F
4.2 * 108 *.01m=F
.042 N/m3=F
Question 7: Two people are carrying a uniform wooden board that is 3.00 m long and weighs 160 N. If one person applies an upward force equal to 60 N at one end, at what point does the other person lift. Begin with a free-body diagram of the board.
Answer:

Forces in x direction = 0

Forces in Y = F1 + F2 - W

Given:

L = 3.00 m F1 = 60 N

W = 160 N F2 = and x2 = ?

Sum of forces and torques = 0

Solved by Saher

And all 1 to 22 chapters formulas in easy format.

Sum Force = F1 + F2 - W = 0

60N + F2 - 160 N = 0

F2 = 100 N

My pivot point is at F2.

Sum of torques = 0

Torque F1 = F1(L - x2)

Torque F2 = 0 b/c at pivot point

Torque W = W(L/2 - x2)

Question 8: What are the properties of wave function?
Answer:

Wave functions contain all the measurable information about the particles Wave functions are continuous.

They allow energy calculations via schrodinger equation.

They establish the probability distribution in three dimensions.

They permit calculation of most probable values of given variables.

Question 9: When a car drives off a cliff, why does it rotate forward as it falls?
Answer:

When the front wheels leave the cliff, the car begins to rotate forward because the front end is already beginning to fall, turn the car around the back axle. Thus by the time it is fully airborne, it is already rotating.

Remember that acceleration due to gravity is around 9. 8 meters/ second PER SECOND, so the front of the car is already falling faster than the rear!

--or--

Well, for a while, the rear wheels are still up on the cliff, but the font wheels are in the air and nothing is holding them up. So as the centre of gravity of the car starts to fall, the front wheels go down while the rear ones are still being supported. Consequently, some rotation is put on the car. Conservation of momentum causes the car to continue to tumble forward even after the real wheels have left the top of the cliff.

Question 10: When can you expect a body to emit blackbody radiation?
Answer:
Waves are emitted when charges accelerate. Blackbody radiation occurs for exactly this reason as well. If a body is heated up, the electrons, atoms, and molecules which it contains undergo violent random motion. Light may emit by electrons in one atom and absorbed in another. Even an empty box will be filled with blackbody radiation because the sides of the box are made up of material that has charged constituents that radiate energy when they undergo acceleration during their random
