1. State the definition of the critical density p. If the density parameter for dark matter is 92cdm.0 -0.25 today, determine the density pedmo today (in units of kg m²³) assuming H? = 73 km s¯'Mpe¯' for the present-day Hubble parameter. [5]
1. State the definition of the critical density ?c?. If the density parameter for dark matter is ?cdm 0?=0.25 today, determine the density ?cdm ,a? today (in units of kgm?3 ) assuming H0?=73kms?1Mpc?1 for the present-day Hubble parameter. [5]
