What is Otto Cycle?
The cycle of a highly idealized gasoline engine can be approximated by the Otto cycle. 1 → 2 and 3 → 4 are adiabatic compression and expansion, respectively; 2→3 and4→1 are constant volume processes. Attend the working medium as an ideal gas with constant g≡Cp/Cv.
a) Compute the effectiveness of this cycle forg=1.4 and compression ratio r = Vi /Vf =10.
b) Compute the work done on the gas in the compression process1→2, assuming initial volume Vi = 2L and Pi =1 atm.
A charge of 1.5µC is carried on two parallel rectangular plates each measuring 60mm by 80mm. Measure the electric flux density. If the plates are spaced 10mm apart and the v

A figure skater who while spinning in place drag her arms in to increase her rotational speed is most closely exhibiting which of the following Answer:- a) Conservation of
1. Cell growth. if V is the volume of a spherical cell, then, in certain cell growth or for some fetal growth models, the rate of change of V is given by dV/dt =kV2/3, where k
A charge q1 is 9.00um is at the origin, and a charge q2 is -4.00um is on the x- axis 0.30m from the origin. find the electric field strength at point P, which is on the y - axis 0.
An atom in a solid state has no degrees of freedom for transnational and rotational speed. At great temperatures due to vibration along 3 axes it has 3 Χ2(directions) = 6 degrees
