1.B 2.C 3.B 4.D 5.B 6.C
Answer:
zirconium
Explanation:
in a liquid, the distance between particles is usually greater than in a solid (with the notable exception of water). Nevertheless, the forces of attraction between particles make liquids, like solids, virtually incompressible. However, the freedom of movement of the particles of liquids is greater than that of the particles of solids.
<u>Answer:
</u>
Maximum height reached by the ball thrown up at 30m/s is 3.06 seconds and the height reached is 45.9 meters
<u>Explanation</u>:
Given:
Initial velocity
To find :
maximum height =?
time taken=?
Solution:
<em>Step 1:Finding the time taken to reach the highest point</em>:
The velocity of the ball at its highest ,final velocity v=0
Using the formula,

Where a is acceleration due to gravity.Its value is
Substituting the values:




<em>Step 2: finding the highest point
</em>
Using the formula

where
s is the maximum highest.
Substituting values





Result:
Thus the maximum height reached is 45.9 meters in 3.06 seconds
