A block has a volume of 0.07 m3 and a density of 3,500 kg/m3. What's the force of gravity acting on the block (and weight) in the air?

Answers

Answer 1

Answer: W = mass * acceleration
and the gravity acceleration is know as 9.81 m/s^2
so we need to calculate the mass ,
from the givens , mass = density * volume
m= 3500*0.07 = 245 kg
subs. in W = m*g ,
W= 245 * 9.81
W = 2403.45 N

Answer 2

This is a little bit weird, but it's not hard if you just
do it one step at a time.

Here's the important part that you need to know
in order to solve this problem:

    All four sides of a square are equal.

Got that ?   Good.
Here we go.

-- First, take the left and right sides.
   They must be equal, so

   2y - 5 = y - 1

Add 5 to each side:    2y   = y + 4

Subtract 'y' from each side:    y = 4 .

The left side is y-1 = 3

The right side is     2y-5 = 2(4) - 5
          = 8 - 5
          =    3 .

Good ! We have the left and right sides equal.
Do we really need to do the other two sides ?
They told us it's a square, so can't we just say
   the top and bottom are also 3 ?
Well, maybe. But maybe they're trying to trick us,
   and the top and bottom aren't really 3 . I think
   we ought to check it out. It's more good math practice.

-- Take the bottom side ... it's 3y-9 .

But you know what 'y' is !
We just calculated that y=4,
so
   3y - 9 = 3(4) - 9 = 12 - 9 = 3 .

Great ! The bottom side is 3 .
