Answer:
The amount of thermal energy that is generated is 1000 joules.
Step-by-step explanation:
Let consider the person diving into a pool as a closed system, that is, a system with only energy interaction with the surroundings. According to the First Law of Thermodynamics, which is a generalization of the Principle of Energy Conservation, the total energy of the system is neither destroyed, nor created, only transformed. The initial gravitational potential energy is transformed into translational kinetic and thermal energy. That is to say:
Where:
- Gravitational potential energy, measured in joules.
- Translational kinetic energy, measured in joules.
- Thermal energy, measured in joules.
The thermal energy is now cleared:
Given that and
, the amount of thermal energy that is generated is:
The amount of thermal energy that is generated is 1000 joules.
Answer:
65 mph
Step-by-step explanation:
Let x mph be Mike's slower rate, then his faster rate is x+10 mph.
1. Mike drove for 3 hours at a slower rate, thus he drove
2. Mike drove for 4 hours ar a faster rate, so he drove
3. In total he drove 495 miles. Hence
