Chapter 39: Problem 34

Express the Hubble constant in SI units.

Short Answer

Expert verified
The Hubble constant in SI units is \(2.27 x 10^{-18}\) s^-1.

Step by step solution

01

Express Hubble constant in km/s/pc

To begin the conversion, first, express the Hubble Constant in terms of kilometers per second per parsec (km/s/pc). Given that 1 Mpc = \(10^6\) pc, we can rewrite it. For instance, if Hubble constant, H is 70 km s^-1 Mpc^-1, we express it as 70 / \(10^6\) km/s/pc = \(7.0 x 10^{-5}\) km/s/pc.
02

Convert kilometers to meters

In this step, convert the distance in kilometers to meters. There are 1000 meters in one kilometer. Therefore, H = \(7.0 x 10^{-5}\) km/s/pc can be rewritten as H = \(7.0 x 10^{-2}\) m/s/pc.
03

Convert parsec to meter

In this step, convert parsec to meters. One parsec (pc) is equal to approximately \(3.09 x 10^{16}\) meters (m). Therefore, now you can write the constant as H = \(7.0 x 10^{-2}\) m/s/ \(3.09 x 10^{16}\) m = \(2.27 x 10^{-18}\) s^-1.
04

Final Answer

Thus, the Hubble constant is \(2.27 x 10^{-18}\) s^-1 in SI units.
