Answer:
B. Time and Space
Explanation:
Matter is a pshyical or corporeal susbtance in general, whether solid, liquid, or gaseous especially as distinguised from incorpeal substance, as spirit or mind, or form qualities, actions, and the
Within this time-and-space boundary, all matter exists. All matter is made up of atoms. Because these atoms take up space in the universe, solids, liquids, and gases are recognized as existing and may be found in all three dimensions.
Time is a figurative term. Space has three dimensions but time only has one.
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.
Answer:
5 feet
Explanation:
First lets imagine that the values are in meters and kg, to make it easier for me.
--------------------------------------------------------------------------------------------------------
The force created by the teacher is 120 × 5 = 600N.
--------------------------------------------------------------------------------------------------------
The force created by the 50 kg student is 50 × 8 = 400N
--------------------------------------------------------------------------------------------------------
The force that needs to be created by the 40 kg student is 600N - 400N = 200N.
To create that force that student needs to sit 200 ÷ 40 = 5m.
So the 40 lbs student is sitting 5 feet from the fulcrum.
Answer:
As the penny falls 320 meters, its vertical velocity increases at the rate of 9.8 m/s

Answer:
What is the atomic number of an atom that has 5 neutrons and 4 electrons? A neutral atom will have the same number of electrons is does protons. Since it has 4 protons, it must have an atomic number of 4. (That makes it beryllium.)
