The acceleration of the bowling ball at the lowest point occurs at 
Answer:
Explanation:
Given that,
Efficiency of heat engine, 
Temperature of hot source, 
We need to find the temperature of cold sink i.e. 
. The efficiency of heat engine is given by :
So, the temperature of the cold sink is 256.2°C. Hence, this is the required solution.
Answer:
Renewable energy: Tidal, solar and wind
Non renewable energy: nuclear power
Explanation:
Renewable energy is any energy in which its source is always replenished or renewed.
While non renewable energy sources cannot be replenished or renewed immediately because of its limited availability of resources.
Most renewable energy sources are natural sources.
Solar, tidal and wind energy are renewable energy known as clean energy. While nuclear energy is a non renewable energy in which its source of energy is fuel ( uranium e.t.c)
