Answer:
t = 0.0735 m
Explanation:
Angular acceleration of the flywheel is given as

now after t = 8 s the speed of the flywheel is given as



now rotational kinetic energy of the wheel is given as




now we have



Explanation:
Hydraulic Pressure-Control, On-Off Deluge Valve
FP-400Y-5DC
The BERMAD model 400Y-5DC is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The 400Y-5DC is activated by a hydraulically operated relay valve, through which opening and closing of the valve can be controlled either with a remote hydraulic command or with a wet pilot line with closed fusible plugs. An integral pressure reducing pilot valve ensures a precise, stable, pre-set downstream water pressure. The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems. The 400Y-5DC is ideal for systems that combine a remote wet pilot line with a high pressure water supply.
The volume of water will increase . If yu subtract the original volume from the new volume of water you will get the volume of the small ball.
The answer depends heavily on what 'objects' you're talking about.
The order goes like this:
Radio, Micro waves, Infrared, Visible, UV (Ultra Violet), X-Ray, Gamma Ray.
