Answer:
A) Gravitational Force is greater in S.
B) Time taken to fall a given distance in air will be greater for F.
C) Both will take same time to fall in a vacuum.
D) Total force is greater in S.
Explanation:
(a) In this case, the gravitational force of S will be greater, because Newton's Second Law states that - F = ma, or weight =mg. g is constant. And mass of the solid metal is heavier.
(b) In this case, the time it will take for F to fall from a given distance in air will be greater than that of S, since the air resistance is not negligible (as in the case of S).
(c) In this, It will take same time for S and F because in a vacuum, there are no air particles, so there is no air resistance and gravity is the only force acting and so objects fall at the same rate in a vacuum.
(d) The total force will be greater in S than F because Force=ma and S is of heavier mass than F.
Answer:
The most common type of descriptive research is the case study, which provides an in-depth analysis of a specific person, group, or phenomenon.
Answer:
3.73994
No,
Explanation:
= Pressure at the bottom of the lake = 3.5 atm
= Pressure at the top of the lake = 1 atm
= Volume at the bottom of the lake
= Volume at the top of the lake
= Temperature at the bottom of the lake = 4 °C
= Temperature at the top of the lake = 23 °C
From ideal gas law we have the relation
The ratio is 3.73994
As Jacques is ascending if he holds his breath his lungs acting like a bubble would expand. Hence, it is not safe to hold his breath while ascending,
<span>The distance "d" you bike varies directly with the amount of time "t" you bike. Therefore,
d </span>α t
To turn it into equality, we introduce k, proportionality constant.
d = kt
We find the value of k from the given conditions. <span>Suppose you bike 13.2 miles in 1.25 hours.
13.2 = k(1.25)
k = 10.8 miles/our
Therefore the equation would be:
d = 10.8t
It is a linear graph with slope 10.8 and it passes at the origin.</span>
