Remember that the left is NEGATIVE
and RIGHT is POSITIVE

16. +3N - 6N = -3N

therefore 3N to the left (because left = -)



17. +5N - 5N = 0N , zero resultant force



18. +6N - 4N = +2N

therefore 2N to the right (because right = +)

scoray [572]

Answer:

2. 200N

3.50kg

4.700N

Explanation:

Weight is another word for the force of gravity

Weight is a force that acts at all times on all objects near Earth.

F=m*g

where g=acceleration due to gravity

2. due to the gravitational fields of the earth , assume gravitational acceleration=10m/s2

F=20*10= 200N

3.same as above

mass=Force/gravitational acceleration

mass=500/10 = 50kg

4.force=mass*gravitational acceleration

force=70*10=700N

3. If atoms are mostly empty space, why can't<br> we walk through walls?
Serhud [2]

Good question

Explanation:

The reason is that walls are made up of more than just atoms. Walls are built up from many things, so with this being said we cannot walk through the walls

PPs why do or should anyone want to walk through walls?
