An Earthlike Planet . In January 2006 astronomers reported the discovery of a planet, comparable in size to the earth, orbiting another star and having a mass about 5.5 times the earth’s mass. It is believed to consist of a mixture of rock and ice, similar to Neptune. If this planet has the same density as Neptune (1.76 g/cm 3 ), what is its radius expressed (a) in kilometers and (b) as a multiple of earth’s radius? Consult Appendix F for astronomical data.

In the fall of 2002, scientists at Los Alamos National Laboratory determined that the critical mass of neptunium-237 is about 60 kg. The critical mass of a fissionable material is the minimum amount that must be brought together to start a nuclear chain reaction. Neptunium-237 has a density of 19.5 g/cm3. What would be the radius of a sphere of this material that has a critical mass?
The cube of iron and the cube of brick have the same dimensions. Each cube has sides of length l = 10 cm. What is the volume of each cube?
The density of iron is ρFe= 7.87 g/cm3. Calculate the mass of the iron cube using the definition of density: ρ = m/V.
Hence, mFe = 7.78+1000= 7830 gram
The density of brick is ρbr= 1.92 g/cm3. Calculate the mass of the brick cube using the definition of density: ρ = m/V. Show your calculation.
Hence, mFe = 1.92 X 1000 = 1920 gram
The water and the oil are both in beakers which have a 3-liter capacity. Each of the major tick marks on the beaker is 1 liter, and each minor tick mark is 0.2 liters. Examine the beakers and determine the volume (in ml) of each liquid.
1 mL= 1 cm^3 = 1cc3 lt = 3x1000 mL= 1000 x 3cm^3= 3000 cc
Because the thermometer has no scale, we’ll have to calibrate the thermometer. Assume the experiment occurs at a (room) temperature of 77 oF.
water reaches the boiling point, T=…
