Answer: Visible light makes up just a small part of the full electromagnetic spectrum. Electromagnetic waves with shorter wavelengths and higher frequencies include ultraviolet light, X-rays, and gamma rays.
Answer:
The two brothers working together will take 7.7 hours to dig the entire ditch.
Explanation:
Assuming T to be the total amount of time taken by both brothers working together, we can say
- 1/T ditch/hour to be the rate at which both brothers dig the ditch together
- 1/14 ditch/hour to be the rate at which the older brother digs the ditch
- 1/17 ditch/hour to be the rate at which the younger brother digs the ditch
So the rate at which both brothers dig the ditch can be calculated by the equation,
1/T = 1/14 + 1/17
T = 238/31 = 7.7 (rounded off to the nearest tenth)
Because the heat of the fire diffuses into the atmosphere and then we absorb it into our body
Students were asked to place a mint in their mouths and determine how long it took for the mint to dissolve. The condition of the mint varied in each student group. One group of students were asked to leave a whole mint in their mouth, not moving it around, and let it dissolve. Another group swirled a mint, while the other groups used mints broken into smaller pieces. See the chart for all of the manipulated variable. After reviewing that data table, what kind of result would you predict for the swirled, whole mint?
A) The time is likely between 10-30 seconds.
B) The time is likely between 40-80 seconds.
C) The time is likely between 90-160 seconds.
D) The time is likely between 100-200 seconds.
ANSWER: B) The time is likely between 40-80 seconds.
EXPLANATION:The time is likely between 40-80 seconds.
By swirling the mint, this is agitating and creating a higher frequency of collisions between the saliva particles and mint particles, increasing the rate of dissolution. Therefore, the time is likely to be less than the mint cut in half but probably more than the mint when it is in small pieces.
