A uniform 5.50kgsquare solid wooden gate 2.00m on each side hangs vertically from a frictionless pivot at the center of its upper edge. A 1.30kgraven flying horizontally at 5.00m/sflies into this door
Calculate the value of a) planks constant and b) the work function of metal from the data obtained.Robert A millikan was attempting to disprove Einsteins photoelectric equation but found that his data
A cubical piece of heat-shield-tile from the space shuttle measures 0.16 m on a side and has a thermal conductivity of 0.065 J/(s·m·C°). The outer surface of the tile is heated to a temperature of 102
Find the centripetal acceleration of a dust particle on the edge of a vinyl record, 0.3m in diameter, rotation at 33.3 rev/min.
Please show your working clearly.
THANKYOU!!!! -frequencyf= 33.3 rev/m
Temperature change time base problem. Suppose V = 28 V, I = 0.1 A, mw = 54 gm, cw = 4.18 J/gm K, mr = 10 gm, and cr = 3.7 J/gm K. If the water is initially at room temperature, how long will it take f
a) the distance the wave moves in one second
b)the distance the wave moves in one time period of the wave
c)the maximum distance moved by the particles on either side of the mean (average) position

A double slit with a spacing of 0.0716 mm between the slits is 2.96 m from a screen.
If yellow light of wavelength 554 nm strikes the double slit, what is the separation between
the zeroth- and first-
Please explain in detail...and only if you know what youre taking about :)-Antimatter is exactly like normal matter in every way except antiparticles have the opposite charge.For example, an antiproto
It says index of refraction value
And then it has this formula
n (material) = 3.00 x 10 ^8 m/s divided by v(material)
n (material) and v (material)... what is this formula finding?The difference of
A wheel rotates clockwise about its central axis with an angular momentum of 730 kg·m2/s. At time t = 0, a torque of magnitude 23 N·m is applied to the wheel to reverse the rotation. At what time t is
1) The speed of a sound in human tissue is about 1600m/s. If an ultrasound pulse takes 1.5x10 to the power of -5 to travel through a tissue, what is the thickness of the tissue?
#2)A 0.500 kg ball w
So Im looking at a table and it says: Velocity of light in the medium
It says air has 3.00
And then ice 2.31
and Heavy flint glass 1.82
So the higher the value the faster light goes in it?... right
The work needed to carry a 9 C charge from point A to point B is 19 J. Calculate the potential difference between
point A and B. Answer in units of V.
How do I solve this? Thank you so much!!-Voltage
if we add a second electron to the He+ ion to form a helium atom, the Bohr model still predicts an ionization energy of -54.4eV (as for He+), since it ignores the Coulomb repulsion between the two ele
