Calculate the standard cell potential at 25 ∘C for the reaction X(s)+2Y+(aq)→X2+(aq)+2Y(s) where ΔrH∘ = -799 kJ mol−1 and ΔrS∘ = -359 J K−1 mol−1 .
A hollow, thin shelled sphere of radius rK=0.08 m and mass
mK=1.8 kg is attached at one end to a rod of mass mS=mK and the
length L=5?rK. The sphere-rod system can pivot without friction
about a horizontal axis at (A),from its equilibrium angular
position, and then released.
A. After what time does the sphere reach the highest point on
the right for the first time?
t= 0.653 s
B. Determine the speed of the sphere when it pivots through...
Gravel Box Ms = 0.700 MK = 0.400 Concrete A 50.0-kg bucket of concrete hangs from a cable, and the other end of the cable is attached to a 70.0-kg box, as shown. A 30.0-kg bag of gravel is sitting on top of the box. The coefficients of friction between the box and roof are shown. Initially, nothing is moving. a. Draw separate free body diagrams for (i) the gravel, (ii) the box, and (iii) the bucket. b. Find the...

The Hydra 70 rocket is a weapon derived from the 70 mm (2.75 inch) Mk 4/Mk 40 Folding-Fin Aerial Rocket developed by the United States Navy for use as a free-flight aerial rocket in the late 1940s. The rocket uses the Mk 66 universal motor, which has a mass of 6.2 kg. The burn time of the motor is 1.07 s. The velocity of the exhaust from the nozzle is about 1030 m/s. Assuming that the burn...
