Cold ocean currents.write notes
Answers
Answer:
in cylinder
diameter is 12 cm
hence radius will be 6cm
height is 15 cm
volume of cylinder is
πr^2h
π ×6×6×15 cm ^3
now, volume of 1 toy
2/3 × πr^3 + 1/3 πr^2 h
1/3 πr^2 ( 2r + h)
height of cone is 3 times r
h = 3r
as 12 toys were recasted..
volume of 12 toys = volume of cylinder
12 ×1/3 πr^2 ( 2r + h) = πr^2h
4 πr^2 ( 2r + 3r ) = π ×6×6×15
4 r^2 (5r) = 6×6×15
r^3 = 6 ×6×15/4×5
r ^3 = 3 ×3×3
r = 3 cm
radius of sphere is 3 cm
height of conical part is 3 ×3 = 9 cm
height of toy is 3 +9 = 12cm

Explanation:
Cold ocean currents are large masses of cold water that move towards the equator, from a level of high altitude to lower levels. They absorb the heat they receive in the tropics, thereby cooling the air above them.
Think of cold currents as currents moving toward the Equator. These waters are colder than the water they are moving into. ... You would be swimming into a current colder than the surrounding water -- thus a cold current. A warm current is just the reverse. A warm current is moving away from the Equator toward the poles.
There are five major gyres: the North Atlantic, the South Atlantic, the North Pacific, the South Pacific and the Indian Ocean Gyre, see figure 1. The Antarctic Circumpolar Current is situated in the Southern Ocean and constantly circles around Antarctica because there are no land masses to interrupt the currents.
