Answer:
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe

A cylindrical tube of length 27.75 cm and radius 2.00 cm is filled with argon gas. The empty tube weighs 188.25 g. The tube filled with argon weighs 188.87 g. Calculate the density. formula =
Answer:
Explanation:
that should help
Density is mass per unit of volume. The density of argon is 1.778 × 10⁻³ gm/cm³.
How are the density, volume, and mass of a substance related?Suppose that a finite amount of substance is there having its properties as:
mass of substance = m kgdensity of substance = d kg/m³the volume of that substance = v m³Then, they are related as:
d = m/v
The volume of the tube = π × r² × h
= π × (2cm)² × 27.75 cm
= 348.716 cm³
Mass of Argon = Mass when tube is filled - Mass when tube is empty
= 188.87 g - 188.25 g
= 0.62 g
Now, the density of the gas can be written as,
Density = Mass / Volume
= 0.62g / 348.716 cm³
= 1.778 × 10⁻³ gm/cm³
Hence, the density of argon is 1.778 × 10⁻³ gm/cm³.

because if its called Pillars creation then something important might be being born maybe
In which direction does centripetal force act on an object?
in the opposite direction of the tangential speed of the object
in the same direction of the tangential speed of the object
toward the outside of the circle in which the object is moving
toward the center of the circle in which the object is moving
Answer:
Centripetal force acts on an object toward the center of the circle
in which the object is moving. That's perpendicular to the object's
tangential velocity.
