Explanation

The motion of a free-falling object can be described by Newton's second law of motion,

force (F) = mass (m) times acceleration (a)

Newton's second law of motion states that F = ma, or net force is equal to mass times acceleration.

The other name for Newton's second law is the law of force and acceleration.

Explanation

A device that is used to convert AC voltage into DC voltage is called A Rectifier.

Inverters and rectifiers are electronic circuits that can change the type of electric current.

a rectifier converts AC to DC.

Explanation

 Electromagnetic force is a scalar quantity.

Force is defined as the product of mass and acceleration and force is a vector quantity.

This is the pair in which one physical quantity is scalar and the other is a vector.

Joule is a scalar quantity.

Explanation

An ocean current is a continuous, directed movement of seawater.

Ocean current is generated by:

• A number of forces acting upon the water including wind
• The Coriolis effect
• Breaking waves
• Cabbeling
• Temperature and salinity differences.

Additional Information:

Ocean floods:

Coastal flooding occurs when dry and low-lying land is submerged (flooded) by seawater

Cyclone:

Cyclones are caused by atmospheric disturbances around a low-pressure area distinguished and often destructive air circulation.

Tsunami:

Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea.
