Answer:
A) Energy is tranferred from Joey to the water. The temperature of the water increases.
Explanation:
At first Joey jumps and gains a height above the water level of the pool, this way has an energy potential initial, as Joey falls into the water his speed is increased that is to say its energy potential is transformed into kinetic energy, and at the moment of impact with the water, this energy kinetic is transformed into heat which is transferred to the water. Therefore the temperature increment.
Note: This is one of the reasons why space agencies are studying spatial asteroids that are directed toward the earth, as these come with great kinetic energy, and great potential energy, if these are of a considerable size can cause catastrophic damage, even if they fall into the ocean, due to the large amount of energy which can cause the instantaneous evaporation of large amounts of water and collateral damage in other areas.
D) The reflected ray travels parallel to the principal axis
C according to my calculations
Answer:
False
Explanation:
A while-loop continues to execute the body of the set of instructions until the condition statement remains true and exits the loop when the condition becomes false.
- While loop is not fetched with the termination condition as its test expression it is fed with the iteration condition in the test expression and if this condition becomes false then only the loop is terminated.
In while loop is followed by a condition called test expression in '()' braces. Then follows the body of the loop which is inside the '{}' braces while the condition remains true.
