A typical person begins to lose consciousness if subjected to accelerations greater than about 5g (49.0 m/s2 ) for more than a few seconds. Suppose a 3.00 x 10^4 -kg manned spaceship’s engine has an exhaust speed of 2.50 x 10^3 m/s. What maximum burn rate |ΔM/Δt| could the engine reach before the ship’s acceleration exceeded 5g and its human occupants began to lose consciousness?
A typical person begins to lose consciousness if subjected to accelerations greater than about 5g (49.0 m/s2) for more than a few seconds. Suppose a 2.40 ✕ 104 kg manned spaceship's engine has an exhaust speed of 2.60 ✕ 103 m/s. What maximum burn rate |ΔM/Δt| (in kg/s) could the engine reach before the ship's acceleration exceeded 5g and its human occupants began to lose consciousness? (Enter the magnitude.)
What pressure of argon gas is required to produce a collision rate of 4.5 × 1020 s−1 at 425 K on a circular patch of surface of diameter 1.5 mm?
How many grams of coffee must evaporate from 350 g of coffee in a 100-g glass cup to cool the coffee and the cup from 95.0 to 45.0 ? Assume the coffee has the same thermal properties as water and that the average heat of vaporization is 2340 kJ/kg (560 kcal/g). Neglect heat losses through processes other than evaporation, as well as the change in mass of the coffee as it cools. Do the latter two assumptions cause your answer to be higher or lower than the true answer?
The excess internal energy of metabolism is exhausted through a variety of channels, such as through radiation and evaporation of perspiration. Consider another pathway for energy loss: moisture in exhaled breath. Suppose you breathe out 22.0 breaths per minute, each with a volume of 0.600 L. Suppose also that you inhale dry air and exhale air at 37C containing water vapor with a vapor pressure of 3.20 kPa. The vapor comes from the evaporation of liquid water in your body. Model the water vapor as an ideal gas. Assume its latent heat of evaporation at 37C is the same as its heat of vaporization at 100.C. Calculate the rate at which you lose energy by exhaling humid air.
Superman leaps in front of Lois Lane to save her from a volley of bullets. In a 1-minute interval, an automatic weapon fires 150 bullets, each of mass 8.0 g, at 4.00 x 102 m/s. The bullets strike his mighty chest, which has an area of 0.75 m2. Find the average force exerted on Superman’s chest if the bullets bounce back after an elastic, head-on collision.
In an industrial process, a fuel-air mixture is fitted with a piston. When the mixture is ignited at a constant pressure of 700mm Hg, 2.0 kJ of energy is released and is found to occupy a final volume of 200L. What would be the initial volume occupied by the mixture if all energy released is converted as work done by the system to push the piston?
A 3.00-g lead bullet at 30.08C is fired at a speed of 240 m/s into a large block of ice at 08C, in which it becomes embedded. What quantity of ice melts?
A coin dropped from a certain building with a height of 3980.59m. If we hypothetically assume that the 403.77μ mol-coin is made of pure nickel and that nickel has a molar mass of 59g/mol, what is the force of the coin as it hits the asphalt?
The pressure in solid copper of mass 100 kg is increased quasi-statically and isothermically at 0°C from 0 atm to 1000 atm (1 atm = 1.01325 x 10⁵ Pa). If you know that p = 8930 kg/m3 , k = 7.16 x 10^-12 Pa^-1, how many kJ of work will arise?
In the hot gases of an automotive engine's cylinders, temperatures may exceed 3100 k. What would be the "root mean square" or "rms" velocity of a hydrogen atom, if one happened to be in that gas after some chemical reaction? The mass of a hydrogen atom is about 1.66x10-27 kg. Give your answer in m/s, but enter only the number.
At what temperature would the rms speed of the helium atoms (mass=6.66x10^-27kg) equal its escape speed from the earth which is 1.12x 10^4 m/s? Answer is given as 60509 K but cannot figure out how that could be it.
