The gravitational potential energy (GPE),is the energy of position given by GPE=mgh
Where m=mass in kilogram, g=acceleration due to gravity, h=height in meters
GPE=0.3×9.8×0.45=1.323J
Work=force X distance
Newtons is a measurement of force
4 meters is your distance 60×4=240
240 joules

All we can say is that the object's volume is about 41 liters. That's the same as the volume of water displaced.
We can't say anything about the object's weight. There is no direct connection between the weight of the object and the weight of the water it displaces.
The frequency of a wave is the reciprocal of its period.
A period of 0.008 sec means a frequency of
1 / 0.008 sec = 125 per sec . (125 Hz)
