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
Answer:
The frequency would not change because the frequency of a simple pendulum does not depend on mass.
Explanation:
Plasma is the state of mater after gases. Its where the gas forms ions. The state is made of charged particles.
So, the best test for plasma is C and D.
The charge of the substance's particles and
The distance between the substance's particles.
Answer:
-5 meters
Explanation:
x = 3t² + 2t − 5
The initial displacement is when t = 0.
x = 3(0)² + 2(0) − 5
x = -5
