Chapter 1, Problem 1.51P
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/cm3), what is its radius expressed (a) in kilometers and (b) as a multiple of earth’s radius? Consult Appendix F for astronomical data.

Earth, the densest planet in the solar system, has a mass of 5.98 x 1024 kg and a volume of 1.08 x 1021 m3. The density of Earth is:(a) 1.81 x 10-4 kg/m3 (b) 5.54 x 10-3 kg/m3 (c) 5.54 x 103 kg/m3 (d) 6.46 x 1045kg/m3
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.

- A high tech company uses a satellite to measure the size of features on the surface of the earth. They use this technology to measure a particular rectangular field and find it's length to be 444 ± 1.8 in meters and it's width to be 198 ± 1.63 in meters.

The quantity RS (with dimensions of length) is dependent on the mass of the black hole M, the speed of light c, and the gravitational constant G.

- On planet Z, the standard unit of length is the foose. Ann the Astronaut is 5.2 feet tall on Earth. She lands on planet Z and is measured to be 88 foosi tall. Her partner Rachael is 92 foosi tall. How tall is Rachael on Earth?arrow_forwardThe SI units of mass density are kg/m3, but there are several other common units. One of the most commonly used units of mass density is gram per cubic centimeter, or g/cc. This is because pure water has a mass density of 1 g/cc. It turns out that 1 mL of liquid is equal to 1 cc of volume. So it is also possible to express the mass density of water as 1 g/mL. This makes water a useful tool since it is possible to use graduated cylinders to measure volumes.An object with a mass of 61.0 g displaces 785.0 ml of water when it is completely immersed. What is the buoyant force on the mass? (Use g = 9.8 N/kg as necessary.)arrow_forwardThe density of the Earth can be expressed by the equation density = C{1.22 -(r/R)}, where R is the radius of the Earth and C is a constant.

Show yourreasoning and all work.arrow_forwardA physicist needs to estimate the density of a cube (all sides of the cube have equal length). Density (in kg/m3)can be found by D = M L3 where M is the mass of the object (in kg) and L is the length of a side of the cube (in meters). Assume the mass M ∼ ·(µM = 1.0, σ2 M = 0.022 ) (i.e. 1.0±0.02) and assume the length L ∼ ·(µL = 0.1, σ2 L = 0.0052 ) (i.e. 0.1±0.005).Assume M and L are independent.(a) Approximate µD.(b) Approximate σD.(c) Write the estimate of the density, along with the estimated error, in engineering (i.e. ±) notation.
