The law of conservation of energy is one of the basic laws of physics and therefore governs the microscopic motion of individual atoms in a chemical reaction. The law of conservation energy states:
In a closed system, i.e., a system that isolated from its surroundings, the total energy of the system is conserved.
In SI units, energy has units of Joules. 1 Joule = 1 kgms.
Some forms of energy:
<span>1.Kinetic energy - energy of motion.2.Potential energy - energy of ``location'' with respect to some reference point.3.Chemical energy - energy stored in chemical bonds, which can be released in reactions.4.Electrical energy - energy created by separating charges; energy stored in a battery, for example.5.<span>Thermal energy - energy given off as heat, such as friction.</span></span>
There are four types of snow crystals. They are called: Snowflakes – are single ice crystals or clusters of ice crystals that fall from a cloud
Answer:
The answer is A.
Explanation:
Photosynthesis stores energy in complex organic molecules, while respiration releases it.
Living organisms in any biome interact through a variety of relationships. Organisms compete for food, water, and other resources. Predators hunt their prey. Some organisms coexist in mutually beneficial relationships (symbiosis), while others harm organisms for their own benefit (parasitism). Still others benefit from a relationship that neither helps nor harms the other organism (commensalism).
Animals found in the Arctic tundra include herbivorous mammals (lemmings, voles, caribou, arctic hares, and squirrels), carnivorous mammals (arctic foxes, wolves, and polar bears), fish (cod, flatfish, salmon, and trout), insects (mosquitoes, flies, moths, grasshoppers, and blackflies), and birds (ravens, snow buntings, falcons, loons, sandpipers, terns, and gulls). Reptiles and amphibians are absent because of the extremely cold temperatures. While many of the mammals have adaptations that enable them to survive the long cold winters and to breed and raise young quickly during the short summers, most birds and some mammals migrate south during the winter
Answer:
D). 8 kg mass
Explanation:
Acceleration of Falling Objects
Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system. ... The stronger the pull of gravity on an object, the greater its weight.
