You are deep in outer space (far from any gravitational sources) and standing at the center of a rotating platform (it lies in the plane z=0, and rotates ccw with angular velocity 2). you look down and see a puck on the platform with coordinates (x, y) (in your, the tt, frame). a) write down newton's 2nd law for the x & y coordinates of the puck as you observe it (2 eqs) b) write down the general solution to these two equations by changing to complex coordinates (i. e. write n = x + iy) and guessing that one of the solutions has the form n = e-iat (what is the form of the second solution, when you have two solutions which have the same form? this arose in taylor's discussion of the critically damped oscillator in section 5.4) c) at time t=0 the puck is launced from position to = (x0,0) with velocity v = (vxo, vyo) (all in your frame). show that the time dependent coordinates obey: x(t) = (xo + vxot) cos(at) + (vyo + nx)t sin(nt) y(t) = -(xo + vxot) sin(t) + (vvo + 1x)t cos(at)

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
