350kg because to get Newton’s it’s mass x Gravity, earths gravity is x10 so 3500 divided by 10 is 350
Answer:
1. the voltage will be 2.35×12.5 = 29.4V
2. the resistance would be 9.0/6.2= 1.45ohms
3. in series they will add up thus 4+8+12= 24ohms
4. in parallel it will be 2.18ohms
Answer:
0.5747 or 57.4%
Explanation:
Your question is not complete so i will assume the right question goes thus;
A Carnot engine extracts 529 J of heat from a high-temperature reservoir during each cycle, and rejects 225 J of heat to a low-temperature reservoir during the same cycle. What is the efficiency of the engine?
Efficiency of a Carnot engine is given by [(Th-Tc) / Th]
using the formula above, the resulting equation will give us; (529-225)/529
=0.574669
It grows every time it needs to grow for the population of the environment
