Isaac and Sakura are both doing a science experiment where they are measuring the temperature of a liquid over time. Graphs that represent each of their data are shown below.

A graph titled Isaac's Experiment has time (minutes) on the x-axis and Temperature (degrees Fahrenheit) on the y-axis. A line goes through points (0, 80) and (2, 70).

A graph titled Sakura's Experiment has time (minutes) on the x-axis and Temperature (degrees Fahrenheit) on the y-axis. A line goes through points (0, negative 80) and (8, 0).

Which statement is correct?
The slope of the graph that represents Isaac’s data is positive, and the slope of the graph that represents Sakura’s data is positive.
The slope of the graph that represents Isaac’s data is positive, and the slope of the graph that represents Sakura’s data is negative.
The slope of the graph that represents Isaac’s data is negative, and the slope of the graph that represents Sakura’s data is positive.
The slope of the graph that represents Isaac’s data is negative, and the slope of the graph that represents Sakura’s data is negative.In your own words, describe how matter is identified.

Explain how you can use a rope to prove that waves transfer energy not matter.

Answers

The rope will transfer energy without transferring matter. The matter will transfer the energy as a medium. What tool would be required to determine the period of a pendulum? A stopwatch.

Waves transfer energy not matter since  waves on a rope are mechanical waves.

Waves on a rope?

When a rope is displaced, we notice that the rope essentially remains at the same position just that it vibrates. These vibrations begin at one end and is eventually transferred across the length o the rope.

This ultimately implies that, waves transfer energy not matter. The waves on a rope are mechanical waves.

What would be the acceleration of a 80 kg box that is being pushed with a force of 20 N but has 5 N of friction on it

Answers

The correct thing to do is subtract the friction from the action force which is 20, making the result 15 N. I believe the answer for the acceleration would be 0.25 m/s. Hope this helped :)
