Answer:
80% increase
Step-by-step explanation:
45 - 25 = 20
20/25 = 0.8
0.8 X 100 = 80
Well first things first
You just subtract 2008-1920 to see how much the year gap is between the increasing percentage of the value of the gem
2008-1920=88
Then we must multiply 120x88
120x88 gives us a value of $105,60

The impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
<h3>What is Impulse?</h3>
An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.
It is expressed as;
ΔP or Change in Momentum = F × t
Where F is force applied and t is the elapsed time.
Given that;
- Mass of baseball m = 0.25kg
- Time of contact t = 0.0075s
- Force exerted F = 18500N = 18500kgm/s²
We substitute our given values into the expression above to determine the impulse.
ΔP = F × t
ΔP = 18500kgm/s² × 0.0075s
ΔP = 18500kgm/s² × 0.0075s
ΔP = 138.75kgm/s = 140kgm/s
Therefore, the impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.

Answer:
50.24
Step-by-step explanation:
The formula for solving circumference is 2 x pi x r
first the radius is 8 (divide 16 by 2 and get radius)
( pi can be 22/7 or 3.14. but I’m taking 3.14 )
second, we have all values, now we just have to substitute them!
Pi = 3.14
R = 8
so when we do 2x 3.14 x 8 = 50.24
I hope this helped!
