1000 miles = 1 609 340 m
2 weeks = 1209 600 s
v = 1609340/1209600 = 1.33 m/s
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 ∝
KE = 1/ 2 * 1252 * 144
as KE = 1/2 * m * v ^2
= 90144 J
No each atom bonds in a different way according to what does it bonds with
I love this one. All the effects of gravity are vertical. There is no horizontal force on the crate, and we are neglecting air resistance, so the horizontal speed of the crate doesn't change. When it gets to the ground, its horizontal speed is still 100 meters per second.
