A plane is being tracked by radar, and data is taken every second in polar coordinates
θ and r
t (sec) 200 202 204 206 208 210
θ (rad) 0.75 0.72 0.70 0.68 0.67 0.66
r (m) 5120 5370 5560 5800 6030 6240
1. Calculate the velocity of the plane as a function of time, where the velocity V is given by:
V= √r^2 + r(θ)^2.
Please compute the derivatives using the most accurate finite-difference method and comment on the choices you made (why did you choose to use a certain method at any given point).

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
