Answer:
Ocean-floor sediments can also be used to determine past climate. ... Ice cores contain more 16O than ocean water, so ice cores have a lower 18O/ 16O ratio than ocean water or ocean-floor sediments. Water containing the lighter isotope 16O evaporates more readily than 18O in the warmer subtropical regions

because television use electricity (electrical energy) and produce sound (sound energy) that we hear while watching tv
Magnetic flux density - It is the force acting per unit current per unit length on a wire placed to magnetic field at right angle.
It is denoted by B
unit of B is tesla (T)
The total no. of magnetic field lines passing through a area is called magnetic flux.
Magnitude of the magnetic flux - It is equal to the area of the surface and having perpendicular direction to the plane of the surface.
Its unit is weber (Wb)
Direction to the magnetic flux density - The direction is north pole to the south pole.
The magnetic field lines are known as lines of magnetic flux.
flux lines are not in direction of force but perpendicular.
