A lot of students tremble with fear when they hear the word “physics” but still more students are seized by fear when they hear the word combination “atomic physics”! They study day and night but still get no results. Don’t give up! We are here to provide you with a special assistance for your atomic physics problems! You don’t have to be daunted by atomic physics any more as we have created a special system for only one purpose – to consider every single atomic physics question of every single student and provide them with the atomic physics answers in the shortest time!

The volume of an iceberg is 664,000 ft^3.
What is its weight (in lb), assuming it is pure ice? (Round your answer to at least four significant figures.)
What is the volume of seawater (in ft^3) it displaces when floating? (Hint: You know what the weight of the seawater is. Round your answer to at least three significant figures.)
____ ft cubed
What is the volume of the part of the iceberg out of the water (in ft^3)?
____ ft cubed
Thank you for the help!
A juniper-wood plank measuring 0.46 ft by 1 ft by 14 ft is totally submerged in water.
(a) What is its weight?
(b) What is the buoyant force acting on it?
(c) What is the size and the direction of the net force on it?

A large tanker truck can carry 21 tons (42,000 lb) of liquid.
What volume of antifreeze (in ft^3) can it carry?
What volume of pure water (in ft^3) can it carry?
A certain part of an aircraft engine has a volume of 1.6 ft^3.
(a) Find the weight of the piece when it is made of silver.
(b) If the same piece is made of aluminum, what is its weight?
Determine how much weight is saved by using aluminum instead of silver.
A box-shaped metal can has dimensions 14 in. by 4 in. by 5 in. high. All of the air inside the can is removed with a vacuum pump. Assuming normal atmospheric pressure outside the can, find the total force (in lb) on one of the 4-by-5 in. sides. (Enter the magnitude.)

in which all partial waves
are completely absorbed up to
d= R/X (qe= 0 for complete absorption)
and unaffected for
t‘> R/X ( qe = l), then
uSc = T(R + A)’

derive black disk scattering
E4 transitions are 44Sc, 52Mn,
86Rb, 93MO,141n, and 202Pb. Look up the partial lifetimes for these
transitions from collections of spectroscopic data, and compare with values
calculated from the Weisskopf estimates.
