As far as I know the answer is centripetal force=weight mv^2 /r= mg v=54.221 m/s

Here's the answer v*v=gh so When h(depth)increases velocity increases v=fλ When the velocity(v) increases fλ has to increase But as f remains unchanged λ increses. Longer the λ is smaller the gap gets comparatively. So the defraction increases.

The answer given is correct it's= 0.09684m The wave length of a standing wave is equal to (distance between the two nodes*2) Think how standing waves are made (by interference of two periodic waves).then you would be able to figure thi out.note that node is the place where the pressure is...

of course it's a curve here's the equation v=u+at (vertical motion) -u sin36=u sin36 -gt t=2u sin36/g s=ut s= u sin36 * 2 u sin36/g s= u*u *2 *sin36 *cos36 / g but mv*v/2= kx*x/2 mu*u/2=kx*x/2 u*u=kx*x/m then s=kx*x *2 *sin36 *cos36 / gm...

I'm really amazed to see so many people thinking that Pyramids are the largest constructions of the ancient world. Jhethawanaramaya in Sri Lanka is bigger than the largest pyrmig in Geesa and was built about 1600(or more I'm not sure) ago. Why don't you people check that out.

The percentage is given considering the weight its the molarity that is conserned when it comes to osmoasis. molarity of 0.9% NaCl is much higher than 20% sucrose. And your definition of osmoasis is wrong.9you have to mention the semi permiable membrane)

Sorry I didn’t see the four or five feet part! The design I described earlier is used in extreme cases. This is the most appropriate design for you purpose. Build a tetragon frame with steel wires and build a smaller on with card board. Put the egg inside the cardboard tetragon and fill...

I'm sure that this isthe answer Velocity of a wave decreases as the water gets shallow. As described in- v*v=gh (v=velocity g=gravity h=depth) as v=fλ (λ=wave length f=frequency) Either f or λ has to decrease. But as f is a constant...

I agree with whozum.An object doesn't necessarilly have to move for it to have mechanical energy. Even an apple hanging from a branch has mechanical energy that is potential energy. And the rock that was picked up contains potential energy which is a form of mechanical enrgy.We can't consider...

W built three egg landers in an egg lander competition and they were dropped off a five storied building they worked brilliantly none of the eggs were even cracked. And one of our landers worked ecxeptionally well even without a parachute. Iwill send you the diagram of that lander. it was a...

Whats to be done here is to use mv^2/r =GmM/r^2 Because it's the centripetal force which resists the attraction towards the sun which depends on the mass of the orbiter and the sun.

Thanks for all your help,got it figured out.

the red shift can easily be explained using doplers effect. And how are you going to explain why some objects show blue shift using your theory.
