Answer:
option A
Explanation:
A soccer field is about 100 meters of length, with the other instruments is possible to make the measure, but it will be very complex and it will take time. Therefore with the 50-m tape, the student will need only two measures.
Complete question is;
Three grams of the same substance in different phases are stored in three different containers. Each container is barely large enough to hold the substance. Which statement can be known about the behavior of the atoms in each container?
A) The atoms in the solid would be moving vigorously around the container.
B) The atoms in the liquid would be vibrating in position.
C) The atoms in the solid would be vibrating in position.
D) The atoms in the gas would be moving slowly around the container.
Answer:
Option C - The atoms in the solid would be vibrating in position
Explanation:
Option A is wrong because the molecules in solids are held together by strong inter molecular forces and therefore can't move about freely but instead will vibrate in their position.
Option B is wrong because the atoms in liquid are more free than those in solids. Thus they will not have room to vibrate.
Option C is correct from the explanation from option A.
Option D is wrong because the atom of the gas would be very loose and free and would therefore be moving very fast around the container
Answer:
His conclusion best illustrates a pessimistic outlook.
Explanation:
As seen in the question above, Ken got 20% of his final grade in the first test he did for this class, that is, there will be other tests that can provide him to reach the grade needed to pass the class. However, even if there are possibilities, he believes that he will not pass the class, he does not have a positive and optimistic view of his future in this class and is sure that he will fail. This negative view of the future is an example of a pessimistic outlook.
Answer:
The bottom of the sea is 25 m below sea level.
Explanation:
Given data
Mass = 6.1 × 
We know that Buoyant force on the tank is equal to gravity force of the tank.
1020 × 
= 6.1 × 
= 598039.21 
We know that
= W × L × H
598039.21 = 300 × 80 × H
H = 25 m
Therefore the bottom of the sea is 25 m below sea level.
