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 ∝
Answer:
The temperature after half an hour is
Solution:
As per the question;
Metabolic rate of the person is 3.0105 J/h
Temperature, T =
Mass of the water,
Time duration, t = 0.5 h = 30 min = 180 s
Now,
Heat,
Thus heat transfer in half an hour:
Now, the temperature of water after half an hour, T' is given by:
where
s = 4186 J
