A student measured the maximum mass of salt that can dissolve in 100mL of water at five different temperatures. Which variable s
Wewaii [24]

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.

Chemical energy stored in food cannot be transformed into mechanical energy true or false
Orlov [11]
If that statement were true, then you would never have any reason to eat.
It might taste good for a while, but it would never help you stand up and
move around.

Where WOULD you get the energy to stand up and walk, if it didn't
come from food ? ?

The whole idea is pretty absurd.  I guess the statement is not true.

A 100 kg person rides in an elevator moving at a constant speed of
Airida [17]

Answer:

Explanation:

All this information only applies to the person. There is an extra tension force if we are talking about the elevator, but we are not. Dont forget to apply the units

Acceleration means change in speed or velocity. The elevator is moving at a constant speed of 3 meters. You wont even know you are moving because there is no change in acceleration. It equals 0

The forces ONLY acting on the person would be the force of gravity pulling them down, and the normal force that the elevator is reciprocating from the person standing on it.

Force = mass x acceleration. You have 100 kg and you are accelerating at 0 m/s. The force is 0. Which makes sense because the force of gravity and the net force completely cancel each other out.

poizon [28]

Answer: B

Explanation:the voltage is just like the force that drives the current through out the circui... When trippled, the force increases and the current increases since the resistance in the circuit remains constant.
