Answer:
Secondary current is 8A
Explanation:
Data :
Primary supply = Vp = 240 V
Secondary supply = Vs = 60V
Primary current = Ip = 2A
Secondary current = Is = ?
Formula : Vp × Ip = Vs × Is
So for secondary current formula becomes
Is = (Vp/Vs)×Ip = (240/60) × 2
Is = 4 × 2 = 8A
I think it’s A because ascending means going up 10,000 then descending is going down 2,000 so in all they are 8,000 feet above the ground
Before it hits the sand bed, the meteorite is accelerating uniformly with
, so that its speed
satisfies

where
is its initial speed and
is its change in altitude. Notice that we're taking the meteorite's starting position in the atmosphere to be the origin, and the downward direction to be negative. Now,

Crafting, reusing
Good luck!
