Well, the surface of still water has surface tension. If there isn't enough mass or weight to break the surface tension, the object will float.
Answer:
480
Explanation:
resistance equals to potential difference divide by electric current
120÷0.25
=480

Kinetic energy is the energy possessed by an object on motion. it is expressed as follows:
KE = 0.5mv^2
where m is the mass and v is the velocity of the object. We calculate as follows:
KE = 0.5mv^2
1.1x10^9 J = 0.5(8.0x10^4 kg) v^2
v = 165.83 m/s
Explanation:
this is a physical property
