It would be wonderful to take a thing that is so distructive and turn into something that would power a city.

are we trained to "like" some harmonies better than others, or is there really an inherent "good sounding" or "bad sounding" combination?

Top is haveing single pin pointed bottom, It is rotating and standing independantly without any supporting is given when it is rotating, whereas same top is falling down after the rotation is completed, Why ? in two wheelers and are all we are balanceing when it is in movement but top is not haveing any other extrodinary forces from out side for balanceing it's position ?

the day we manage to travel faster than the speed of light, will we be able to follow a point of light reflected from the earth and see into the past?

Ok so I have already worked these problems out but I'm just wondering what you guys get. Here are the problems:

Bill is in outer space on his way out of L.A. A force of 10 N pushes on Bill. Suddenly, when Bill has reached a speed of 250 mph, another 10 N force, directed opposite to the first force, also pushes on Bill. Now, with both forces acting on Bill, what happens to Bill's speed?

a) Bill will stop.
b) Bill will slow down.
c) Bill will speed up.
d) Bill will continue moving at a constant velocity.

Number 2:

Two blocks of masses 20 kg and 8 kg are connected together by a light string and rest on a frictionless level surface. Attached to the 8 kg mass is another light string which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.6 m/s^2, then what is the tension in the connecting string between the blocks?

a) 12 N
b) 6.0 N
c) 20 N
d) 4.0 N

Please provide why you feel the answer is right. Feel free to send me an IM. :)

I believe in steady state theory.....how can anything have infinite density...If there is infinite density then may be it is possible to achieve infinite acceleration,to reach Speed of light...It i absurd according to me....I want to hear your arguement..!!!

suppose A is starting point.Three resistors are connected in parallel.
R=r1=r2=r3=1,and E1=3volt,E2=2volt,E3=1 volt.
suppose a point A is starting point and after that R is resistor,from resistor,three parallel resisters are connected say r1=r2=r3=1,and E1=3 volt,E2=2 volt and E3=1 volt. outside the circuit point B is the end.What will be the potential difference between point A&B

Man pushes a 22 kg box across a frictionless floor. The box is initially at rest. He initially pushes on the box gently, but gradually increases his force so that the force he exerts on the box varies in time as F = (8.6 N/s)t. After 3 s, he stops pushing. The force is always exerted in the same direction.

What is the velocity of the box after 3 s? answer in m/s

How far has the man pushed the box in 3 s? answer in m

What is the average velocity of the box between 0 s and t? answer in m/s

What is the average force that the man exerts on the box while he is pushing it? answer in N

HELP!

Block B in the image weighs 711 N. The coefficient of static friction between block and table is 0.25; assume that the cord between B and the knot is horizontal. Find the maximum weight of block A for which the system will be stationary, and explain your answer. Thanks
