Consider the situation of an area of land being heated periodically at the surface. A model for the temperature Θ(x, t) of the soil at a distance x metres below the surface at time t is ∂Θ ∂t = D ∂ 2Θ ∂x2 , where Θ(0, t) has an annual sinusoidal variation about a mean temperature of −5 ◦ C with amplitude 10◦ C, and ∂Θ ∂x → 0 as x → ∞. (a) Verify by substitution that the following...

51. Using the scenario below, model the population of bacteria a in terms of the number of minutes, t that pass. Then, choose the correct approximate (rounded to the nearest minute) replication rate of bacteria-a. Hint: The replication rate is the coefficient of the exponent. A newly discovered bacteria, a, is being examined in a lab. The lab started with a petri dish of 3 bacteria-d. After 1 hours, the petri dish has 57 bacteria-a. Based on similar bacteria, the...

1. Use the Keynesian cross model and show graphically in which direction will equilibrium level of income (or output) change. For each of the following, write down the formula for the size of the change of income (i.e. write down the formula for ∆Y): (i) An increase in government purchases (ii) An increase in taxes (iii) An increase in government purchase and an increase in taxes of equal amount (Nb: You must draw a SEPARATE graph for parts (i) and...

Analysis Model Tutorial A4.00-m length of light nylon cord is wound around a uniform cylindrical spool of radius 0.500 m and mass 1.00 kg. The spool is mounted on a frictionless axle and is initially at rest. The cord is pulled from the spool with a constant acceleration of magnitude 2.30 m/s? (a) How much work has been done on the spool when it reaches an angular speed of 4.00 rad/s? (b) How long does it take the spool to...

just now i sent this questions.
this is the answer given. however the answer i afraid
that he used formula that is not for constant surface temperature
and noncircular formula.
this is the formula foe the noncircular tube. because
the question ask about triangle.
my problem is, i cannot answer question 1(b) that ask
the heat transfer coefficient, h. please help me. thank you.
this pic is a note on constant surface temperature.
