Answer: The color of an image is equal to the color of the item forming the picture. When you have a take a observe your self in a mirror, the color of your eyes would not alternate. The reality that the color is equal is proof that the frequency of light would not alternate upon reflection.
Answer:
The temperature change in the calorimeter will be lower
Explanation:
Water is an example of a molecular substance. They have relatively low melting points and boiling points usually below 300° C . Water reacts with metals to a degree varying with their position in the electrochemical series.
The specific heat of water is 4179.6 Joules which is relatively high . This typically implies that water absorbs a larger amount of heat but the increase in temperature of its boiling points is relatively low. Thus; in the 200-mm test tube that contains water and was subsequently added to the calorimeter , the heat present was initially absorbed by the water and that does not result to an increase in the temperature change in the calorimeter. Thus the temperature change in the calorimeter will be lower.
Conservation is the understanding that the quantity of an object stays the same even when it changes in appearance. A concrete operational child between ages seven and eleven understands this fact because of the development of his cognitive ability while a preoperational child does not.
For example, change the tea cup of a 5 year old boy from an oblong shape to a short round shape of the same size, he begins to cry because he believes the change in cup has translated to a change in quantity.
In addition, change the denominations contained in an amount of money owned by each of the children of these two categories, the pre operational child seems a lot bothered, but the concrete operational child has enough knowledge of conservation to be undisturbed by this re-arrangement.
Answer:
the imparting or exchanging of information or news.
Explanation:
Gravitational potential energy is equal to (mgh) so 1.5•9.8•200=2940
