A block of body weighs 15 N in springbalance in air and its weight in water shows 12 N. If the density of water is 1 gm/cc, what is the specific gravity of
the block ?
EXPLANATION:
Specific gravity or relative density is mass in air/mass in air−mass in water.
= 15/15 − 12
= 15/3
= 5
therefore, the specific gravity or relative density in 5
Hence,
option (D) is correct answer.
Hope it helps❣

Answer:
the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares.
SI unit: Square metre
In SI base units: 1 m2
