Answer: The angle between force and displacement should be θ = 90° for minimum work. The angle between force and displacement should be θ = 0° for maximum work.
Answer: Option (B) is the correct answer.
Explanation:
Convection is defined as a process in which a fluid (liquid or gas) is heated and the cooler liquid (more dense) settles or sinks at the bottom whereas a hotter material (less dense) will rises to the top.
For example, ice being less dense (cooler material) will float in a lake whereas liquid water being more dense will sink at the bottom.
Thus, we can conclude that situation in which convection currents most likely occur is within the water in a lake as ice forms on the top.
Answer:
GAS, LIQUID, CLOUDS
Explanation:
Water can be in three states: solid, liquid and gas, passing from one to another depending on the pressure and temperature.
In this complementation exercise.
When the water cools down the GAS goes to the LIQUID state, these small drops unite and form the CLOUDS
Explanation:
All living organisms metabolize. That is the definition of life. So jr answer is no animal or organism that does not consume food.
Answer:
C-) Compound machines are made from two or more simple machines
Explanation:
Simple machines use the principle of Lever, where a force multiplied by a distance is used. That is why a simple machine does not produce electricity. Simple machines must be composed of at least two parts. For this reason the combination of simple machines results in a compound machine.
