Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Three engineers are independently estimating the spring constant of a spring, using the linear model specified by Hooke’s law. Engineer A measures the length of the spring under loads of 0, 1, 2, 4, and 6 lb, for a total of five measurements. Engineer B uses the same loads, but repeats the experiment twice, for a total of 10 independent measurements. Engineer C uses loads of 0, 2, 4, 8, and 12 lb, measuring once for each load. The engineers all use the same measurement apparatus and procedure. Each engineer computes a 95% confidence interval for the spring constant. If the width of the interval of engineer A is divided by the width of the interval of engineer B, the quotient will be approximately _____. Numeric Response

The temperature is 25 ℃ at the surface of the water, and the water temperature at the bottom of the pool is 10 ℃. What is the volume of the balloon at the surface after it has come into thermal equilibrium with the surroundings
State whether the following statements true or false 1. The type I error and type II error are related. A decrease in the probability of one generally results in an increase in the probability of the other. 2. The size of the critical region, and therefore the probability of committing a type I error, can always be reduced by adjusting the critical value(s). 3. An increase in the sample size n will reduce α and β simultaneously. 4. If the null hypothesis is false, β is a maximum when the true value of a parameter approaches the hypothesized value. The greater the distance between the true value and the hypothesized value, the smaller β will be. 5. The power of a test is the probability of rejecting H0 given that a specific alternative is true.

When two springs in series, with constants k1 and k2 respectively,support a mass, the effective spring constant is calculated as:k = k1*k2 / k1+k2 A 420 g object stretches a spring 7 cm, and that same object stretches 2.8 cmanother spring. Both springs are attached to a common rigid support and then toa metal plate, as shown in the figure of springs in series. Then the object joins thecenter of the plate (figure of springs in series). Determine: (a) the effective spring constant.(b) the position of the object at any time t, if the object is initially releasedfrom a point 60 cm below the position ofequilibrium and with an upward velocity of 1.2 m / s.Consider the acceleration of gravity as 9.8 m / s2.
A solid steel cube is stored in a freezer, where the temperature is −20.0 ̊C. While the cube is in the freezer, you measure its side length (L) to be 1.75050 meters. The cube is then placed outside for a long time, so that the temperature of the cube reaches the temperature of the air outside. As a result, the side length increases to 1.75170 meters due to thermal expansion. The coefficient of linear expansion for steel is 12.0×10−6 ̊C−1. (a) What is the temperature of the air outside? Give your answer in degrees Celsius ( ̊C). (b) What is the volume of the cube when its temperature is 20.0 ̊C? Give your answer in cubic meters (m3).
A physics lab consists of a large ball attached to a wire. Students hold on to one end of the wire, then whirl the ball around in circles and count the number of rotations per second. One group finds these numbers: ball mass= 320 gram, wire length= 1.3m, number of rotations/sec=2.5. The wire is made of steel with a diameter of 1mm and a Young's modulus of 20x10^10 N/m^2.How much does the wire stretch due to the tension on it? Should the students correct their data for the wire stretching?
