For example, the magnetic flux is defined as 

Flux = BAcos(angle)  (Tm^2)

Why is it the product of B and A. What does the multiplication of T and m^2 suggest. 

Also, for B = flux/A. What is the meaning of division here. Why is per area squared and what does it suggest.

I am really confused here with the product and division and I hope someone can clear this.

I know that in fission its about 200Mev, but how do you get that number. I got 1782.9 Mev or 7.59Mev/nucleon. plz helppp

Ok for nuclear fusion, helium, i have calculated the energy to be 28.37 MeV (7.0925 mev/nucleon), and for nuclear fission, uranium 235, i have calculated the energy to be 1782.9 Mev (or 7.59 Mev/nucleon).

so clearly nuclear fission shows more energy released than nuclear fusion, just by a tiny. but, i thought nuclear fusison produces more energy than fission. someone plz help

Can someone provide me with the arguments as to why nuclear fission is better than nuclear fusion. I need it for my physics assignment.

This question is in sequence to the previous one, ill write that down as well. Anyway this question states. What speed will the 73 kg skydiver reach two seconds after exiting the plane? in your answer develop a general equation of velocity (v) for any Time (t). (plz show all working out and use partial fraction method)

the Previous question which I have done is; a 73 kg skydiver approaches a terminal velocity of (-) 55 m/s. what will the terminal velocity be of a 85 kg skydiver?.

How do I find tangential velocity if i don't have angular velocity? any formulas?

I dont understand how to solve this question, when you're only giving the range and the height to find the initial angle and initial speed. (do you assume the angle?). could some one help with this problem using calculus only.

A car driver failed to notice the bend in a horizontal road, crashed her car over a steep embankment into a muddy reek bed which lies 11m below the road level.

A policeman found the wreckage in the mud, 50 meters from the point at which the car left the road.

The insurance company insits the river was speeding, driving at 140 km/h in a 100km/h zone. Evaluate their argument by determining if the driver was speeding using vector methods.

Discuss the relationships in projetile motion between: height and the initial angle and range and the initial angle

Hey guys can someone help me, I am making a wind power from paddle pop sticks for my physics assignment and the question i came up with is to investigate the rotational energy. But i really dont know how to do it. the formula for the rotational energy is

KE=1/2 I w^2

And i dont really understand what the I and w do or stand for. so can some help me it will mean alot. and also where on the internet will i find secondary data for this that some has done in the past. thank alot

how do i present expository talk in the perception of Anzac Day?

this is to do with my assignment. Can someone help

can someone help with this question.

Which polymer is made by the polymerization of methyl methacrylate?

Can someone plz help me with this question, I have a test soon

briefly explain why it is difficult to breakdown plastics and what experiment could you design to help in this process.

Can some plz help me with this question.

Variable resistors are often used in voltage divers. if a variable resistor is used in the voltage divider circuit below at R1 and this resistance is lowered to a smaller value, what effect does this have?

Ok guys I am confused with the four equations regarding rust. can someone plz explain what all these mean, it will be alot of help. I have exams tomorrow, thanks.

(1) Fe(s) ----> Fe^2+ (aq) + 2e^-

(2) O2(g) + 2H20(i) + 4e^- ------> 4OH^- (aq)

(3) 2Fe(s) + O2(g) + 2H2O (i) ------> 2Fe(OH)2 (s)

(4) 4Fe(OH) (s) + O2(g) + 2H2O (i) -------> 4Fe(OH)2 (s)
