Answer: black
Explanation:
A colour filter is a filter that lets only one colour pass through it. For example, a red filter lets only red colour pass through it, while a green filter lets only green light pass through it.
In this example, we have a red and blue jacket. At first, we put a red filter: this filter lets pass throuhg only the red light. Then, we put a green filter: this filter lets pass only green light through it. However, there is no green light coming from the previous filter (since only red light passes through it), so the jacket appears black (no colours).
Answer:
10 Mil. J
Explanation:
multiplyed balls and divided by 5
Answer:
Water!
Explanation:
Specific heat is described as the amount of energy required to raise one gram of a substance one degrees celcius. Therefore, the higher the number for specific heat the more energy that is required to raise the temperature of that object. Since 4.184 is greater than 1.760, more energy is required to heat water 1 degree celcius than wood!

A 2.0 kilogramme chunk of heated copper is cooled by being lowered into 5.0 kg of water. Water goes from 30 degrees Celsius to 52 degrees Celsius in only a few hours. determine the copper's temperature before submerging it in water. In this case, the water's temperature is 24 degrees, and when we plug this number into equation 2 for water, we get the copper's temperature as 100 (0.387) (200-x) = 400 (4.187). ( x-20)
100 (0.387) (200-x) = 400 (4.187) ( 24-20)
: to give (something) over to the power or control of another : surrender The troops would not yield the fort to the enemy. 2 : to give in He yielded to temptation. 3 : to produce as a natural product These trees yield fruit.
Solving it yields x = 26.89 degrees, indicating that the temperature of ;copper is 26.89 degrees.
