Answer:
The effect of gravity on object makes objects stable and not floating in the air . It also makes any object thrown up to return back
When we see the words "Which statement ... ", we know right away that there
will be a list of choices, and we're expected to select our answer from that list.
Strangely, the list of answer-choices for this question has been lost.
Similarly, when we see the words "The picture shows ... ", it's hard to fight
the impulse to look around. In the present situation, <em>that's</em> missing too.
If the diver is just standing there, then the reaction force provided by the cliff
against his feet must be exactly equal to his weight. If the vertical forces acting
on the soles of his feet were not balanced, then his feet would be accelerating
vertically.
His weight is (mass) x (gravity) =
(93 kg) x (9.8 m/s²) = <em>911.4 newtons</em> (about 205 pounds) .
That's also the strength of the upward reaction force provided by the cliff.
Answer:
5 feet
Explanation:
First lets imagine that the values are in meters and kg, to make it easier for me.
--------------------------------------------------------------------------------------------------------
The force created by the teacher is 120 × 5 = 600N.
--------------------------------------------------------------------------------------------------------
The force created by the 50 kg student is 50 × 8 = 400N
--------------------------------------------------------------------------------------------------------
The force that needs to be created by the 40 kg student is 600N - 400N = 200N.
To create that force that student needs to sit 200 ÷ 40 = 5m.
So the 40 lbs student is sitting 5 feet from the fulcrum.
The car travels a distance of
(8.0 m/s) (5 s) + 1/2 (10.0 m/s²) (5 s)² = 165 m
Answer:
Chidera is the stronger individual pushing the box with a net force of 5N to the left.
Explanation:
Chidera is using more force meaning they are stronger and the net force is 5N because when you plug in the equation
F1 = 30 + F2 = -25 = 5N
you get 5N
