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.
Answer:
1,600 to 1,700 kilocalories per day
Explanation:
Gravitational Potential Energy GPE = mg∆h. 12. A 5.0 kg mass is initially sitting on the floor when it is lifted onto a table 1.15 meters high at.
Answer:
1.6 m/s
Explanation:
First you need to find the momentums of each disc by multiplying their velocities with mass.
disc 1: 7*1= 7 kg m/s
disc 2: 1*9= 9 kg m/s
Second, you need to find the total momentum of the system by adding the momentums of each sphere.
9+7= 16 kg m/s
Because momentum is conserved, this is equal to the momentum of the composite body.
Finally, to find the composite body's velocity, divide its total momentum by its mass. This is because mass*velocity=momentum
16/10=1.6
The velocity of the composite body is 1.6 m/s.
B.) Carbon Dioxide because the carbon is surrounded by oxygen
