A probe on a dwarf planet collects 5 moles​ [mol] of dust material. The​ sample, which completely fills a cube with a side length of 4 centimeter​ [cm], weighs 0.19 newtons​ [N] on the dwarf planet. The density of the material is determined to be 3160 grams per liter​ [g/L].Determine the gravity of the dwarf planet in units of meters per seconds squared ​[m/s2​].

A helium-filled balloon has volume 3.8_m³, temperature 25.4°C, and pressure 1 atm while at sea level. If the balloon rises to 27000 ft, where the temperature is 3.5°C and the pressure is about 1/3 of its sea-level value, then find the new volume of the balloon. 10.56.m3 20.65_m3 18.71 m3 19.31 m3 А.

The density of gold is 19.3 g/cm^3. What is the volume of a 100 g hole ingot?

The following data are given for the pressure and temperature variation in air as a function of elevation: Elevation in [m] 0. Temperature in [°C]_pressure [atm] 28 1. 1000. 25 0.796 2000. 19 0.6314 3000. 12 0.4982 4000. 3 0.3905 5000. -1 0.3043 6000. 11 0.2356 You want to check if these measurements are correct. You are going to use a balloon and rise in the corresponding altitudes. If the balloon weighs 1000kg (all included, weight of yourself, equipment, inflated part etc) calculate the volume of inflated part of the balloon, so that the initial acceleration is 15m/s?. Assume that the balloon is a sphere and neglect the deflated part of the balloon as far as volume is concerned. Can you verify all measurements with this volume of the balloon? What kind of adjustments do you need to make in order to complete your mission?

Atmospheric pressure on Earth at its surface is 101 KPa (101 kilopascals or 101,000 N/m2). Which of these statements is true?     If we pump out the gas in a closed container leaving only 1 billionth of the original gas there will still be more than 1010 (10 billion) atoms per cm3 in the container.     If we pump out the gas in a closed container leaving only 1 billionth of the original gas there will be fewer than 100 atoms per m3 in the container.     When we reduce the pressure in the container while keeping the temperature constant, the number of atoms per m3 must stay constant.     At 1 atmosphere, the number of atoms/m3 in air at room temperature is about 109, one billion atoms.

The number density of gas atoms at a certain location in the space above our planet is about 0.75 × 10!1 m²³, and the pressure is 2.9 x 10- 10 Pa in this region. What is the temperature in this region, in degrees Celsius? T =

You are with an excursion party on an exploration of the surface of Mars. You find a small lake of water of that 1.76 m. Assume the density of the freshwater is unchanged on Mars. You measure the absolute pressure at the bottom of the lake to be one 161,800 Pa. What is the absolute pressure (in atm) at the surface of the lake. Assume the value of G on Mars is 3.72 m/s^2

Pd Pd 1. Let's consider a toy model of nuclear fission. Suppose an nucleus of Uranium-235 (92 protons, molar weight of 235 g/mole) "splits" into two "daughter" nuclei of Palladium (46 protons each) – this is not how it really happens, but it's a very simple model that actually gives fairly accurate results. The radius of the original U-235 nucleus is about 7.4 x 10-15 m. (a) If the Pd nuclei each have half the volume of the U nucleus, which is reasonable, and they are "touching" right after the split, how far apart are their centers? (b) Using conservation of energy, what will be the sum of the kinetic energies of the Pd nuclei when they are far apart from each other? (c) That's energy of one atom undergoing fission, so what, then, is the energy released by the fission of 1 kg of U-235? Express this in Joules and also in kilotons of TNT, where 1 kt = 4.2x1012 J. (The Hiroshima bomb yielded about 15 kt) (d) How many kwh (kilowatt-hours) of energy is this, (1 kwh = 3.6x10° J), and (if…

Saturn's moon Titan has a mass of  1.3452 x 1023 kg , a diameter of 5,150 km, and an atmosphere made mostly of N2  at a constant temperature of  -179 degrees Celsius.   Assume that the pressure at the surface is 50% more than on Earth. What is your best estimate of Titan's atmosphere's R constant?
