Question

7 The density of Repper is. 8,agcm? What doch
beite density in kg m 3​

Answer 1

Answer:

1) The Young's modulus a rubber string 8 cm long and density 1.5 kg/ m3 is 5×108N/m2, is suspended on the ceiling in a room. The increases in length due to its own weigth will be.

2) 1000 kg/m3

Water as the reference with its highest density at 3.98 °C is ρ = 1 g/cm3. The correct SI unit is ρ = 1000 kg/m3.
