C, moves at a constant speed. since no force is acted on it, the energy it uses to go forward does not change either
Answer:
Exothermic because energy is a product
Explanation:
Since energy is a product, heat was released, meaning that the reaction is exothermic.
A large male cougar living in the Cascade Mountains kills a deer or elk every 9 to 12 days, eating up to 20 pounds at a time and burying the rest for later.Except for females with young, cougars are lone hunters that wander between places frequented by their prey, covering as much as 15 miles in a single night.Cougars rely on short bursts of speed to ambush their prey. A cougar may stalk an animal for an hour or more
hope this helps in any way ! :)
Answer;
B. Mass and energy are equivalent.
Explanation;
-Each of the letters of E = mc2 stands for a particular physical quantity.
E is the energy, m is the mass and c is the speed of light (m/s)
Energy = mass x the speed of light squared
-The equation E=mc2 explains nuclear fusion, how matter can be destroyed and converted to energy and energy can be converted back to mass. It explains the atomic energy produced by nuclear power plants and the atomic energy released by atomic bombs.
-The equation tells us that mass and energy are related, and, in those rare instances where mass is converted totally into energy, how much energy that will be.
