Q1. Ideal gas helium flows through a well-insulated nozzle at stable state. The temperature and velocity at the inlet are 90 °C and 30 m/s, in that order. At the exit, the temperature is -18 °C and the pressure is 3.10 bar. The mass flow rate is 1.25 kg/s. using the ideal gas model, and neglecting potential energy effects, determine the exit area. Take cp, He to be 5.193 kJ/kg·K. Answer in m².
Q2. Two boxes, m1 = 1.0 kg with a coefficient of kinetic friction of 0.10, and m2 = 2.0kg with a coefficient of 0.20, are placed on a plane inclined at 0 = 30o.
(a) What acceleration does each box experience?
(b) If a taut string is connected to the boxes, with m2 at first farther down the slope, what is the acceleration of each box?
(c) If the initial configuration is reversed with m1 starting lower with a taut string, what is the acceleration of each box?
What is the maximum height, y2, if the object is thrown with a speed of v2 = 1.99v1 from the surface of Jupiter's moon Io? The acceleration due to gravity on Io is g2 = 1.79 m/s2. Give the reply as a multiple of y1.
If air resistance & other effects are ignored how far away did the shell hit.
n object of mass "m" specific heat "Cp" & surface area "As" is initially at a temperature "To". Rate of Heat gained by Object = Rate of Heat Lost by Gas m, Cp, h, A & Tg are all constants.
The magnitude of the acceleration due to gravity
What type of car was involved in the hit and run
A block of mass 2.7 kg being released from rest on a 1m frictionless plane, inclined at an angle of 40 degree. The block sided down the inclined and struck second block mass of 3.7 kg. If the two blocks stick together, with what speed would they move..
