<span>Easy, take the top off your Thermos bottle filled with hot coffee. Assuming perfect insulation, that hot coffee is isolated from the environment; but when the top is opened the heat can now escape to that environment.

Answer:
b) in a direction that makes its potential energy decrease.
Explanation:
- As the electric field has the direction that would take a positive test charge under its sole influence, the positive test charge, will have an increase in its kinetic energy.
- Due to the conservation of energy, in absence of non-conservative forces, this increment must be equal and opposite to the change in electric potential energy, which will be always negative, independent of the sign of the charge.
Answer:No
Explanation:
No
As the train is accelerating so train velocity will be more as compared to the ball and thus will cover more distance as compared to the ball.
When the ball is thrown upward with some velocity, it also possesses the train velocity at the time of throwing but as time passes velocity of train increases due to acceleration of the train. This causes the ball to fall behind the point of launch.
I think the correct answer would be <span>Particle A orbits the nucleus, and Particle B is located in the nucleus. I think Particle A represents the electrons while B represents protons and neutrons. Hope this answers the question. Have a nice day.</span>
D. endothermic
Explanation:
Since the chemosynthesis reaction uses up heat and other inorganic compounds to produce food for themselves, the process is endothermic.
- In an endothermic reaction, heat is absorbed from the surrounding.
- The surround will then become colder at the end of the reaction.
- Since the chemosynthesis reaction uses up heat, it is an endothermic reaction.
- Exothermic reactions liberates heat to the surrounding.
- The surrounding becomes hotter at the end of the change.
