Density is a property of a material which describes the mass of a material per unit volume. Density is said to be slightly dependent on temperature. We look at the density of water at different temperatures:
<span>
100 </span>°C: 958.4 kg/m^360 °C: 983.2 kg/m^320 <span>°C</span>: 998.2 kg/m^3
Therefore, warm water has a lower density than water in colder temperature.
It uses the voltages and sound freq. in the air to measure the wave lengthths
The Answer is D: Reactor products charge huge batteries.
The weight on earth of a book with a mass of 16 kg will be 65N
