Answer:
Explanation:
The reaction can be represented by this nuclear equation: 23892U → 23490Th + 42He + Energy.
Answer:
The correct answer is:
2.6 m3 (B)
Explanation:
SF unit stands for Stowage factor unit. Stowage factor is the volume occupied by one unit of mass (weight) when stowed in cargo space. SF expresses the unit in cubic meters (m³) or cubic feet. SF is a unit of measurement that indicates how much space (volume) a particular unit of cargo occupies in a ship's cargo compartment
The sequence which represents the relationship between temperature and volume:
higher temperature --> more kinetic energy --> more space between particles higher volume
Explanation:
The above sequence is based on the Charles' law. This law states that at "a fixed mass of gas" and "at constant pressure", volume is directly proportional to temperature.
When the molecules in a container "collide with the wall", the pressure and momentum increase. Due to the increase in temperature the kinetic energy also increases. Thus, when the "momentum perpendicular" to the wall of the container is reversed it will have larger value. To reduce the rate of the collisions and to keep the pressure constant, the volume will have to be bncreased.
