Pick up the correct statement from the following
The ratio of the up flux and down flux just above the snow surface, is called albedo
Spectral albedo of snow is calculated for the semi-infinite snow thickness
Water equivalent height of snow is the height of water column obtained by melting snow.
A homogeneous snow pack is one whose average grain size does not vary with depth.

Pick up the correct statement from the following:
Permeability is a measure of conducting the magnetic lines of force in the material.
Permeability is a measure of the extent to which magnetic lines of force can penetrate a medium.
Permeability is expressed as the ratio of the magnetic flux density (B) to the field strength of the magnetizing field.
The force between the magnetic poles is inversely proportional to the permeability of the medium.

Pick up the correct statement from the following:
In remote sensing technique, the observation place, is called a platform
Platforms may be either stationary or mobile
Spatial resolution of the imaging system becomes poorer with increase of platform height.
Area coverage of the imaging system increases with the increase of the platform altitude.
