Answer:
This is an example of a food chain
Explanation:
Think of it as a chain reaction. The grass feeds and nourishes the prairie dog. Upon eating the prairie dog, the coyote gets the nutrients from both the grass the prairie dog ate and from the prairie dog itself.
Answer:
c = λ x ν
v =c/λ=(3*10e8)/(5.00 x 10e-5)=6000000000000
f = v/λ =6000000000000/5.00 x 10e-5=120000000
Explanation:
Explanation:
Solar panels are visible on roof tops on homes and businesses. Solar thermal technology transforms solar energy to heat, which is then used to heat homes, businesses and even swimming pools, or transformed again into electricity.
In an endothermic reaction products are <u>HIGHER </u>than reactants in potential energy and <u>LESS </u>stable.
Explanation:
Energy is input into the reaction in an endothermic reaction. This means the products are of a higher energy level than the reactants. Therefore the reaction increases Gibb's free energy and reduces entropy. Remember in thermodynamic stability involves an increase in entropy and a decrease in Gibbs free energy. Therefore the products are less stable than the reactants. This is why endothermic reactions do not occur spontaneously like exothermic reactions.
