Question A9 On absorption of a single neutron, plutonium Pu-239 can undergo fission into xenon Xe-134 plus zirconium Zr-103 plus three neutrons. The masses of these nuclei are, mpu-239 = mxe-134 = 133.905 amu, and mzr-103 = 102.927 amu. Calculate the energy given off in this nuclear reaction. 239.052 amu,

I watched a lot of Looney Toons when I was a kid, and liked that the Roadrunners legs would spin for a second or two before their claws caught traction. a. With a coefficient of kinetic friction 0.2 what acceleration will the roadrunner experience while their feet are sliding accross the ground? b. How far forward will the roadrunner drift in a half second, starting from rest under this acceleration? c. After catching traction the Roadrunner accelerates away, travelling 10 m to get offscreen in one fifth of a second. What was their coefficient of static friction?

Plz use g = 9.8 m/s2 to find if needed

The 32-inch ceiling fan spins at 60 RPM and accelerates steadily to 130 RPM in nine seconds. A. Determine the speed (ft / s with two decimal places) for the point 15 inches from the center of the fan 16 seconds after the beginning of the above movement. B. Specify the time (s with two decimal places) for the fan to rotate 125 revolutions. Draw a Free Body Diagram if necessary in part A or part B or both.  Please urgent ??? thank you

Mtotal An ultracentrifuge accelerates from rest to 9.93 x 10° rpm in 1.87 min. What is its angular acceleration in radians per second squared? angular acceleration: rad/s? What is the tangential acceleration of a point 8.90 cm from the axis of rotation? tangential acceleration: m/s? What is the radial acceleration in meters per second squared and in multiples of g of this point at full revolutions per minute? radial acceleration: m/s? radial acceleration in multiples of g:
