Answer:

Ocean currents are streams of water flowing constantly on the ocean surface in definite directions. The ocean currents may be warm or cold. The warm ocean currents originate near the equator and move towards the poles. The cold current carry water from polar or higher latitudes to tropical or lower latitudes. For example the Labrador Ocean current is a cold current while the Gulf Stream is a warm current. The ocean current influence the temperature conditions of the area. Warm currents bring about warm temperatures over land surface. The areas where the warm current and cold currents meet provide the best fishing grounds of the world. For example seas around Japan and the eastern coast of North America. The areas where a warm and cold current meet also experience foggy weather and therefore navigation becomes difficult.

In causes form

Climatic Conditions: Currents influence the climatic conditions of the regions in which they flow. The warm Equatorial currents raise the temperature of the region in which they flow. Similarly, the cold currents lower the temperature of the places where they flow.

A uniform cylinder of radius 40 cm and mass 28 kg is mounted so as to rotate freely about a horizontal axis that is parallel to
lbvjy [14]

Answer:

I' = 2.34 kg.m².

Explanation:

Given ,R= 40 cm = 0.4 m

m = 28 kg

d= 6 cm = 0.06 m

The mass moment of inertia of the cylinder about center given as

I=\dfrac{1}{2}mR^2

By using Parallel axis theorem

I'=\dfrac{1}{2}mR^2+md^2

Now by putting the values

I'=\dfrac{1}{2}mR^2+md^2

I'=\dfrac{1}{2}\times 28\times 0.4^2+28\times 0.06^2

I'=2.34 kg.m²

There the answer will be 2.34 kg.m².

How many neutrons does element X have if its atomic number is 48 and its mass number is 167?
Llana [10]
If its atomic number is 48, then it has 48 protons in the nucleus
of each atom.  Any more mass than that is supplied by the neutrons
that are mixed in there with the protons.

If the mass is 167, and 48 of those are protons, then there are

             (167 - 48)  =  119 neutrons

in each nucleus.
