Lifting a weight 10 times is a kind of ISOTONIC contraction. Holding a heavy machine part steady while securing it in place may be categorized as ISOMETRIC contraction. Lifting heavy cans and putting them on a shelf may be called an ISOTONIC contraction. Flexing your leg muscles and holding the flex is an ISOMETRIC contraction. Lifting your heavy book bag several times is good ISOTONIC contraction.
Just do it lol life is short
when you have cancer in the brain it's literally known as brain and neck cancers or the most common brain tumors are known as gliomas
Your example shows that you add a 0 to the end of how many heartbeats you get throughout 6 seconds which was 7 so that would give you 70, however in Sarah's example it doesn't tell us how many times her heartbeats in 6 seconds so I can't give you the answer, but if that's how the question is supposed to be then the answer would be 60 for all.
I hoped that helped! Let me know if you have any questions!
Have a great day/night! :)
