The correct Answer is:
To solve the question regarding Hubble's law, we can break it down into the following steps: ### Step 1: Understand Hubble's Law Hubble's law describes the relationship between the distance of galaxies from Earth and their recessional velocity (the speed at which they are moving away from us). ### Step 2: Identify the Formula The formula for Hubble's law is given by: \[ V = H \times r \] where: - \( V \) is the recessional velocity of the galaxy, - \( H \) is the Hubble constant, and - \( r \) is the distance of the galaxy from Earth. ### Step 3: Interpret the Components - **Recessional Velocity (V)**: This indicates how fast a galaxy is moving away from us. - **Hubble Constant (H)**: This is a value that describes the rate of expansion of the universe. It is usually expressed in kilometers per second per megaparsec (km/s/Mpc). - **Distance (r)**: This is the distance from Earth to the galaxy, measured in megaparsecs (Mpc). ### Step 4: Conclusion Hubble's law indicates that the farther away a galaxy is, the faster it is moving away from us. This relationship provides evidence for the expansion of the universe. ### Final Answer Hubble's law is related to the speed of galaxies and can be expressed through the formula \( V = H \times r \). ---
