What do u think about Engineering Simulation Programs?

I know that its an aid for Engineering,Are there any disavantages in using them,i mean u loose any capability of imagining urself n analysing?

Can any-one tell names of some such programs other than MATLAB,PSPICE for Electrical n Electronics Engineering.

An interesting phenomenon around here... LOTS of people answering relativity questions referring to the increase of mass as speed approaches c.

This is an obsolete interpretation. In modern physics literature, the word "mass" always refers to rest mass. The variable M always refers to mass, which always refers to rest mass.

It's obsolete for very good reasons: you can't correctly calculate effects of gravity using "relativistic mass;" relativistic mass is not invarient, but rest mass is. Even if you're using it to illustrate changes of inertia, it's different in different directions: you'd have to give a particle a different mass for each of x,y, and z motions. Scalar, invarient mass becomes a noninvarient vector. Messy.

When you explain that bodies cannot travel at c by explaining that they get more and more massive, it easily misleads the asker into thinking that if they were to travel at c they would become fatter and fatter in their own reference frame, which is clearly untrue.

You are working as a consultant on a video game designing a bomb site for a World War I airplane. In this game, the plane you are flying is traveling horizontally at 44.8 m/s at an altitude of 130 m when it drops a bomb.

(a) Determine how far horizontally from the target you should release the bomb.
(b) What direction is the bomb moving just before it hits the target?

This is the question I'm having trouble with. It shouldn't be that hard, but it's just not clicking for some reason. I don't necessarily want someone to do the problem (that's my job) but tell me how I should go about solving it. Thanks.

Best Friends Tim, Bob and Dave. Each contribute £5 a total of £15 therefore each share is 5

They purchase a TV for £15

After they all leave the shop. The shop keeper tells his cashier there has been a mistake and the cost was only £10. Take these £5 coins and give it to Tim, Bob and Dave.

The cashier keeps 2 and hands back £1 to Tim, £1 to Bob, and £1 to Dave.

Tim has now paid a total of £4, as so Bob and Dave.

If 3 x 4 = 12 and the cashier has £2. 12+2 = 14

Where is the other £1?
