Question one A body oscillates with simple harmonic motion along the x-axis. Its displacement varies wit time according to the equation X = (4.0 m) cos( nt+) Where t is in seconds, and the angles in the parentheses are in radians. a. Determine the amplitude, frequency and the period of the motion. b. Calculate the velocity and acceleration of the body at any time t. c. Using the results to (b),determine the position, velocity, and acceleration of the bod =Is. d. Determine the maximum speed and maximum acceleration of the body. e. Find the displacement of the body between t=0 and t= 1 s. f. What is the phase of the motion at t-2 s?.

3. on your graph, the data points between the black squares are data for elements with atomic numbers 3 through 9. locate these elements on your periodic table. what term or description would you use to identify these elements with respect to the periodic table?

We want to calculate the total metabolic heat generated by a singing canary taking into account heat transfer by radiation, convection and exhaling air. the air temperature is 20 oc, canary’s body internal and surface temperature is 33oc, external body surface convective heat transfer coefficient is 25.2 w/m2 .k, temperature difference between the inhaled and exhaled air is 4.3 oc, the ventilation rate is 0.74 cc of air per second, specific heat of air is 1.0066 kj/kg.k and density of air is 1.16 kg/m3 . assume the canary’s body to be a cylinder with 7 cm diameter and 9 cm length, and heat exchange is from the side as well as the top and bottom of cylinder. calculate 1) the net rate of heat lost by radiation, assuming heat gained by the bird through radiation from the surroundings is 11.5 w; 2) rate of heat transferred by convection to the surrounding air; 3) rate of heat transferred in the exhaling air without considering any internal evaporation; 4) total metabolic power.
