Answer:
Explanation:
If Ig be moment of inertia about an axis through centre of mass and I be moment of inertia through any other axis parallel to earlier axis , then according to theory of parallel axis ,
I = Ig + Md²
where M is mass of the body and d is distance between two parallel axis.
So I is greater than Ig.

An epiparasite is a parasite that parasitizes another organism that is also a parasite. Epiparasites are also called hyperparasites or secondary parasites. They feed on another organism, but they do not kill the organism they feed on.
24 knots is the maximum wind velocity for a 30 crosswind if the maximum crosswind component for the airplane is 12 knots.
What is crosswind component?
Although you should always prepare to land the aircraft into the wind, in practice the wind only occasionally blows directly down the runway. You will typically be landing with at least a small amount of crosswind. There is a limit to how much direct crosswind an airplane can land in. Only a portion of the wind is operating as a direct crosswind when it is blowing at a shallow (acute) angle to the runway.
The following are the variables needed to solve for the crosswind component:
Runway and wind direction
Wind speed

Answer:
31.92 h
Explanation:
We'll begin by calculating the number of half-lives that has elapsed. This can be obtained as follow:
Original amount (N₀) = 1
Amount remaining (N) = ⅛
Number of half-lives (n) =?
N = 1/2ⁿ × N₀
⅛ = 1/2ⁿ × 1
Cross multiply
2ⁿ = 8
Express 8 in index form with 2 as the base.
2ⁿ = 2³
n = 3
Thus, 3 half-lives has elapsed.
Finally, we shall determine the time. This can be obtained as follow:
Half-life (t½) = 10.64 h
Number of half-lives (n) = 3
Time (t) =?
n = t / t½
3 = t / 10.64
Cross multiply
t = 3 × 10.64
t = 31.92 h
Therefore, it will take 31.92 h for lead-212 to decay to one-eighth its original strength.
