From 70 mph, the hefty Challenger SRT Hellcat came to a stop in only 159 feet. Thatâs impressiveâand in the neighborhood of the 150- and 156-foot stops we recorded in our long-term Camaro and Mustang.
1 Answer. , works at Studying. Gas giants do have a solid core. Its mostly hard rock, and is surrounded by hydrogen and light gases. It is believed that due to the high pressure , the hydrogen near the core is metallic, but the exact physical composition is a mystery.
(1) When a star exhausts the hydrogen in its core, it becomes a giant or supergiant. The layer immediately above the core becomes hot enough to initiate the fusion of hydrogen into helium. The star now has THREE main layers: ( 1 1) Helium core (inner layer): Releases energy as it shrinks in radius. ( 2 2) Fusion shell: Releases energy as it fuses hydrogen into helium. ( 3 3) Hydrogen envelope (outer layer): Absorbs energy, and swells greatly in size.
