Answer:
200J
Explanation:
work done = force x distance
= 20 x 10

Answer: The answer is B, The variable that should go on the x- axis is the temperature of water.
Explanation: In an experiment, we must have two variables; the independent variable and the dependent variable.
If the results of the experiment is reported in graphical format, the independent variable is plotted on the x axis while the dependent variable is plotted on the y axis.
In this case, the independent variable is the temperature of the water while the dependent variable is the mass of salt dissolved in 100 mL of water.
Therefore, the variable that should go on the x- axis is the temperature of water.
Silt soil is usually more fertile than other types of soil, meaning it’s better for growing plants/crops
I would say the correct answer would be light travels faster in medium 3 then medium 2.
