I wonder what comes after quantum theory. Is there anything smaller in scale and more fascinating than quantum physics? I really want to know.

It will continue the exponential growth that we have seen recently in computing technology.

It depends tho. Some people are better at math, some are good at physics. I know I struggle with physics but math is easier for me.

nothing

there would be nothng else. it is just ethers.

Homework Statement find the functional groups in the following compound: Homework Equations C8H16O4The Attempt at a Solution I know there is an ether but there is also something else. What is it? I have tried to find a group that is in the compound, but I have had no luck. It seems to be only...

light is refracted when it enters another medium. this is based on the index of refraction of the medium the light enters. Denser mediums have higher indexes, which leads to lower speeds of light. Although acceleration or deceleration usually apply to matter, in this case it would make sense to...

Homework Statement A uniform crate with a mass of 14.1 kg rests on a floor with a coefficient of static friction equal to 0.551. The crate is a uniform cube with sides 1.21 m in length. If a horizontal force is applied to the top of the crate, what is the magnitude of the horizontal force...

at the top of the path, the normal force the bucket exerts on the water is 0. therefore, applied force, which is equal to normal force, is 0. Thus mg=(m)(v2/r) solving for v gets 5.94 m/s.

the normal force and gravity must equal the applied force. But if that is the case, then ay is 0 and the problem is unsolvable.

Homework Statement You swing a 6.5 kg bucket of water in a vertical circle of radius 3.6 m. What speed must the bucket have if it is to complete the circle without spilling any water? mass=6.5 kg r= 3.6 Homework Equations ay=(v^(2)/(r)) may= A-N-Mg The Attempt at a Solution I know...

Homework Statement A catapult fires at an angle of 40.02 and has an initial velocity of 5.463. Find the vertical displacement at t=.38 seconds. I know the following from the problem and logic vo=5.463 t=.3824 g=9.8 angle=40.02 I calcuated the following voy=vosin40.02 voy=3.5133 Homework...

lol. I am so really new to physics.

Homework Statement A shot-putter throws the shot with an initial speed of 4.0 m/s from a height of 4.5 ft above the ground. Calculate the range of the shot for each of the following launch angles. a. 20 degrees b. 30 degrees c. 40 degrees Vo=4 yo=4.5 Homework Equations y = yo +...

For #1 then, what is the acceleration. And what would vf be.
