Answer:
Cubic meters is the unit of volume.
Explanation:
Volume :
Volume is the multiplication of height, width and length of the solids.
In mathematically term,
Where, w = width
h = height
l = length
Put the unit into the formula
This is the unit of volume.
We know that,
Square meters is the unit of area.
Liters per cubic gram is the unit of density.
Gram per cubic centimeter is the unit of density in CGS.
Hence, Cubic meters is the unit of volume.
Answer:
a) 147.95 Mpc
Explanation:
Using Hubble's formula
where;
v = radical velocity
= Hubble's constant
d = distance
Given that:
The average radial velocity of galaxies in the Hercules cluster v = 10,800 km/s
Also using = 73 km/s/ Mpc ; we make distance d the subject of the formula:
Then distance d can be written as:
d = 147.95 Mpc
b)
Now, if the Hubble constant had a smaller value, then for a given velocity the distance to the galaxy will increase because distance d is inversely proportional to
i.e
d ∝
