Answer:
0.29D
Explanation:
Given that
F = G M m / r2
F = GM(6m) / (D-r)2
G Mm/r2 = GM(6m) / (D-r)2
1/r2 = 6 / (D-r)2
r = D / (Ö6 + 1)
r = 0.29 D

Answer:
Explanation:
From <em>https://epgna.com/stop-condensation-shipping-container</em>
"[C]ontainer condensation occurs when the walls of a container become cooler than the dew point of the air found inside the container... Once this occurs, the moisture falls out of vapor into liquid form, which then builds and collects on the walls and roof"
Answer:
Explanation:
The drawing is missing but we can still answer.
In fact, for a stone being whirled on a tabletop, the tension in the cord provides the centripetal force that keeps the stone in circular motion; therefore we can write:
where
T is the tension
m is the mass of the stone
v is the speed
r is the radius of the circle
For the first stone, we have
(1)
While for the second stone,
(2)
since m and v are identical for the two stones. We know that the first cord is longer, such that the radius of the circle in the 1st case is twice that of the second case:
So, substituting into (1),
which means that the tension in the longer cord is half the tension in the shorter cord.
mass and acceleration have a nice day
