Question

Find the Mass of each of these weights? A. 98N B.80N C. 0.98N

Answer 1

We can't really know for sure, unless you specify the gravitational acceleration.

Explanation:

If you are talking about these objects on Earth, then the gravitational acceleration is around `9.81 \ "m/s"^2`.

We know that weight is given by the formula,

`W=mg`, where `m` is the mass of the object in kilograms, and `g` is the gravitational acceleration.

Now, we can solve the problems.

`A).`

We got:

`98 \ "N"=m*9.81 \ "m/s"^2`

`m=(98 \ "N")/(9.81 \ "m/s"^2)`

`m~~10 \ "kg"`

So, the first object's mass is around `10` kilograms.

`B).`

We have:

`80 \ "N"=m*9.81 \ "m/s"^2`

`m=(80 \ "N")/(9.81 \ "m/s"^2)`

`m~~8.2 \ "kg"`

So, the second object's mass is around `8.2` kilograms.

`C).`

`0.98 \ "N"=m*9.81 \ "m/s"^2`

`m=(0.98 \ "N")/(9.81 \ "m/s"^2)`

`m~~0.1 \ "kg"`

`m~~100 \ "g"`

So, the third object's mass is around `0.1` kilograms or `100` grams.
