The Concorde was a supersonic aircraft used for trans-Atlantic travel in the 1980s and 1990s, having a length of 61.6 m when sitting on the ground on a typical day when the temperature is 18.0 °C. The Concorde is primarily made of aluminum.

The titanium shell of an SR-71 airplane would expand when flying at a speed exceeding 3 times the speed of sound. If the skin of the plane is 400 degrees C and the linear coefficient of expansion for titanium is 5x10 -6 /C when flying at 3 times the speed of sound, how much would a 10-meter long (originally at 0C) rod portion (1-dimension) of the airplane expand?
A 1 kg metal bar at 50°C is placed in a bucket of ice. How much of the ice will melt assuming no heat loss? (Specific hear capacity of the metal = 500 J kg-1 0C-1, latent heat of fusion of ice, Lf = 334kJ/kg)
On a hot summer day, the temperature of air in Arizona reaches 117°F. What is the speed of sound in air at this temperature? (The speed of sound at 0°C is 331 m/s. Use the conversion 0°C = 273 K as necessary.) m/s
Why does a concert violinist must usually retune his instrument when he enters a warm room?
At what wind speed does −10ºC air cause the same chill factor as still air at −29ºC ?
The accepted value for the speed of sound in dry air is 331.50 m/s at 0 °C. This speed increases by 0.607 m/s for each additional °C. Compute the accepted value for the speed of sound in air at a room temperature of 27 °C, also known as 300 K because T = 273.15 + t ( Here t is in degree Celsius).
When the length L of aclock pendulum is held constant by controlling its temperature,the pendulum’s period T depends on the acceleration of gravity g.The period will therefore vary slightly as the clock is moved fromplace to place on Earth’s surface, depending on the change in g.By keeping track of DELTA T, we can estimate the variation in g fromthe equation T = 2π(L/g)1/2 that relates T, g, and L. A clock with a 100-cm pendulum is moved from a location where g = 980 cm/sec2 to a new location. This increases the period by dT = 0.001 sec. Find dg and estimate the value of g at the new location.
I need help with this problem and an explanation of why its the answer described below: (g = 9.03 m/s^2 is the answer but I need an explanations as to why it's the answer.)
You are driving in the hot Nevada desert (40oC and 15%rh) on vacation in your 1973 Chevrolet Caprice Classic, retracing the steps of Raoul Duke and his trusty attorney Dr. Gonzo as featured in Hunter S. Thompson’s book Fear and Loathing in Las Vegas, when they drove to cover the Mint 400 motorcycle race. Suddenly a puff of smoke appears from under the hood, and when the temperature in your car begins to rise, you realize that your air conditioning system has just broken, miles away from any service station. As panic starts to set in, you recall Dr. Timusk mentioning something in your Building Science lecture about “adiabatic cooling”. As you start to sweat, you wish you had paid more attention in class as the details seem fuzzy at first. But then you see the spray bottle of water in the back seat and it all starts to become clear. You recall that by misting water into the dry, hot desert air inside the car, you should be able to cool it “adiabatically”. A. Given that the air is at 40oC…
The goal in this problem is to find the growth of an ice layer as a function of time. Call the thickness of the ice layer L. (a) Derive an equation for dL/dt in terms of L , the temperature T above the ice, and the properties of ice (which can leave in symbolic form instead of substituting the numbers). (b) Solve this differential equation assuming that at t=0 , you have L=0 . If you have studied differential equations, you will know a technique for solving equations of this type: manipulate the equation to get dL/dt multiplied by a (very simple) function of L on one side, and integrate both sides with respect to time. Alternatively, you may be able to use your knowledge of the derivatives of various functions to guess the solution, which has a simple dependence on t. (c) Will the water eventually freeze to the bottom of the flask?
(a) Deter-nine the power of radiation from the Sun by noting that the intensity of the radiation at the distance of Earth is 1370 W/m2. Hint: That intensity will be found everywhere on a spherical surface with radius equal to that of Earth's orbit. (b) Assuring that the Sun's temperature is 5780 K and that its emissivity is 1, find its radius.
Satellites designed to observe the radiation from cold (3 K) dark space have sensors that are shaded from the Sun, Earth, and the Moon and are cooled to very low temperatures. Why must the sensors be at low temperature?
