Ответ:
1) Fapx = 19,6 H
2) m = 21,25 kg
3) P = 188,65 H
Объяснение:
1)
V = 250cm3 = 0,0025m3
ῥ = 800 kg/m3
F apx - ?
PosB'yasanna
F apx = ῥgV
F apx = 800*9,8*0,0025
F apx = 19,6
2)
V = 0,0025m3
ῥ = 8500 kg/m3
m - ?
PosB`yasanna
m = ῥV
m = 8500*0,0025
m = 21,25kg
3)
F apx = 19,6 H
m = 21,25kg
P - ?
PosB`yasanna
P = mg-F
P = 21,25*9,8-19,6
P = 188,65 H
