One of the children on the merry-go-round is not holding on tight enough. If the radius of the merry-go-round is 1.3m, and the child falls off the edge at the maximum velocity of 11 rad/s, what is his
A white light bulb emits
a. infrared light
b. electromagnetic energy
c. photons
d. all of the above-d. all of the above
All light bulbs emit photons, as photons are basically packets of light energy
If a merry-go-round has an initial angular velocity of 6rad/s when a parent gives it a good push to speed it up to 24rad/s in 4 seconds, what is the angular acceleration due to the push?-alpha = delta
Let me explain what I am trying to do.
I want to write an equivalancy principle something to the effect
[time]=e*[constant propagation of 1d space]
Here is what I got
(d pi/2 1/3 (lambda(x y z)^n 1
ok i have no idea what this means
IF F=Bqv
solve in terms of v
Solve in terms of q
Solve In Terms of B
can someone answers it and explain it so i may use it as an example-It simply means re-arrang
How would falling into water make for a softer landing in terms of the definition of impulse (impulse being the product of force and the time interval during which the force acts. Impulse produces cha
If I am correct, the sun, because it is so massive, makes and occupies a dent in space. In the fabric of space earth is higher up. In a sense are we actually looking down on the sun?-While the gravita
Suppose a parent gives the merry-go-round another good push. This push delivers an angular acceleration of 7rad/s^2. If the radius is still 1.3m, and the total mass with the kids is 490kg, how much to
A bullet of mass 45 g is fired at a speed of 220 m/s into a 5.0-kg sandbag hanging from a string from the ceiling. The sandbag absorbs the bullet and begins to swing. To what maximum vertical height w
According to the first law of thermodynamics, energy is neither created nor destroyed. What does this say about a substance or object that is emitting light?-Matter converts to energy (and vice versa)
A cylindrical resistor is made of so me material. The resistor has a rresistance of 2900 (ohms) at a temperature oof 293 K.
Note: the resistivity of the material is p0= 1.20 (ohms) and the resistor ha
An object of mass 50 kg is thrown vertically upward witha velocity 100m/s after 5 sec,it blasts and gets divided in two parts .One part of mass 20 kg goes upward witha velocity 150m/s. find the veloci
two objects of mass m and 2m are suspended through a smooth pulley by a mass less wire, initially both the masses are kept at the same level with a height 13.08m from the ground level.

A bizarre state of matter dubbed 5/2 Quantum Hall Liquids represents enticing new findings this week in the worldwide search for materials that support fault-tolerant quantum computing.
ScienceDaily (Oct. 22, 2008) — McGill University researchers have discovered a new state of matter, a quasi-three- dimensional electron crystal, in a material very much like those used in the fabricat
