Henry heavyweight weighs 1400n and stands on a pair of bathroom scales so that one scale reads twice as much as the other.
what are the scale readings?

The scales readings are 933.3 N and 466.7 N.

Explanation:

Given that,

Weight = 1400 N

We need to calculate the reading of scale

We know he has twice the weight on one scale and his total is 1400 N. These can be written as two simultaneous equations .

....(I)

.....(II)

Put the value from equation (II) into equation (I)

Now, Put the value in the equation (I)

Hence, The scales readings are 933.3 N and 466.7 N.

d) physical means can be used to separate the components of air.
