Yes, that statement is true.
Microchips are specifically designed to make computers process information much faster, and make the devices a lot more portable.
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:
d. the atomic number remains the same.
Explanation:
First at all it's important to know how to read nuclear information

X is the atomic symbol, A the mass number and Z the atomic number of the element.
Gamma rays emitted on gamma decay are characterized as 
If we write the nuclear equation for the decay, we have that:

The sum of the mass numbers and atomic numbers on the right side has to be equal to the left side numbers of the equation, that means the mass number and the atomic number remains the same for the resulting atom to preserve the equality.
