What is the formula for finding your maximum heart rate

Answers

Answer 1

Answer: According to the American Heart Association, the broad,
approximate guideline for your MAXIMUM heart rate is:

   -- take 220
   -- subtract your age
   The unit is "beats per minute".

But there are many things that have an effect on this number.
A few of them are:
-- your age
-- your weight
-- any medicines you're taking
-- HOW you measure your heart rate.

If you're planning any REGULAR activity that will play with
your heart rate, you really ought to discuss it with your doctor
before you jump in.

A rectangle has a length of 5.50 m and a width of 12.0 m. What are the perimeter and area of this rectangle?

Answers

to find the perimeter of the rectangle, you do 2(a) + 2(b), so when you add 11 and 24, you get a perimeter of 35 meters.

to find the area, you multiply a and b together and get an area of 66 meters squared.

When astronauts travel to the moon, their bodies experience a lower gravitational pull than on Earth. Which type of pull are they experiencing?

Answers

Answer:

The pull the astronauts feel in the moon will be gravitational too.

Explanation:

The pull will be gravitational too because there's a gravitational force exerted by the moon over the astronaut, this force keeps pulling the astronaut towards the moon surface but it's weaker than in earth because the mass of the moon is significantly less that the mass of the earth.

They are experiencing the pull of leaving the atmosphere

which one would have more gravitational mass? one kilogram of iron dropped from 200 meters height or one kilogram of paper on the ground?

Answers

Neither of those objects has more or less mass than the other has. The mass of an object does not depend on its motion or its location. Mass is Mass. The unit of mass is the kilogram. One kilogram is one kilogram. Their masses are equal.

the piece of paper because gravitational forces between 2 objects depend on the distance between their centre points and the mass, so since they are both the same mass, then the only factor which would determine the force is the distance. The distance between the centre of the earth and the paper is smaller than the iron, so the force would be greaater
