When a liquid or has carries heat- Convection
When waves transfer heat- Radiation
Answer:
0.48 m
Explanation:
I'm assuming that this takes place in an ideal situation, where we neglect a host of factors such as friction, weight of the spring and others
If the mass is hanging from equilibrium at 0.42 m above the floor, from the question, and it is then pulled 0.06 m below that particular position. This pulling is a means of adding more energy into the spring, when it is released, the weight compresses the spring and equals its distance (i.e, 0.06 m) above the height.
0.42 m + 0.06 m = 0.48 m
At the highest point thus, the height is 0.48 m above the ground.
The answer is Plant A got sufficient water to produce chlorophyll. Tim kept two identical green plants in his garden and labeled them A and B. He watered plant A every day and plant B once a month. After a month, the leaves of plant A remained green but the leaves of plant B turned yellow. The best statement that explains the difference in color is that Plant A got sufficient water to produce chlorophyll.
I think the correct answer from the choices listed above is option A. In this experiment, sunlight is an independent variable. It is the variable that cannot be changed James no matter what. Hope this answers the question. Have a nice day.
