Because the density of water in g/cm 3 is 1.0, the SG of an object is will be almost the same as its density in g/cm 3. However, specific gravity is a unitless number, and is the same in the metric system or any other measurement system. It is very useful when comparing the density of two objects.
Supreme Court justice Antonin Scalia dies at 79. Antonin Scalia, the staunchly conservative supreme court justice, has died at the age of 79, prompting an immediate political struggle over the future direction of the United States, even as tributes were being paid to honor his service.
During the next four years, the new president will likely nominate not only Scaliaâs replacement but also an additional 3 new justices. Since 1971, the average age of retirement for a Supreme Court justice has been just under 79 years. Ginsburg is 83, Kennedy is 80, and Breyer will be 78 in mid-August. The new justices will set the direction of the Supreme Court and the values that guide it for the next generation.
