Answer:

Air is matter because it takes up space and has mass.

A way to prove this is by inflating a balloon. Before inflating, the balloon was empty and shapeless. When the balloon was filled with air you know it filled with something. That would be matter.

Answer:

According to the image, the approximate QT interval is 0.4 seconds.

Explanation:

The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.

Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.

In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:

    0.04 seconds X 10 mm = 0.4 seconds.

Then, the estimated QT interval is 0.4 seconds.
