Answer: Mechanical Energy
Explanation:
According of law of conservation of energy, energy can neither be created nor be destroyed. It can only transformed from one form to another.
When electric sharpener works by using electrical energy, it is being used to drive the blades of the sharpener and is being converted to mechanical energy which is then converted to heat energy and the sharpener gets warm.
Electrical energy is the energy possessed by virtue of motion of electrons.
Mechanical energy is the energy possessed by a body by virtue of its position and motion.
Heat energy is the transfer of thermal energy from hotter body to colder body.
c. Finish this sentence to describe what happens to potential energy: As the height of an object increases…
d. Which has more potential energy, a bowling ball on the floor or a grape on the floor? Explain.
Answer: a. 7.84 J
b. 196 J
c. The amount of potential energy increases.
d. None of them. Since both objects are in the floor assuming that the height is zero.
Explanation:
B. One carries warm water and another carries cold water.
C. One begins at the equator, and another begins near the South Pole.
D. They travel to different hemispheres.
Answer:
B. one carries warm water and another carries cold water
The correct answer is B. One carries warm water and another carries cold water.
The Brazil Current and the Gulf Stream are both ocean currents that transport water in different parts of the world. The Brazil Current flows along the eastern coast of South America in the South Atlantic Ocean, while the Gulf Stream flows along the eastern coast of North America in the North Atlantic Ocean.
The Brazil Current carries warm water from the tropics towards the higher latitudes, while the Gulf Stream carries warm water from the Gulf of Mexico towards the North Atlantic. In contrast, the Brazil Current carries warm water and the Gulf Stream carries cold water.
Therefore, option B is the correct answer as it accurately describes the difference between the Brazil Current and the Gulf Stream.
