Answer:
it gets hot and more hot until it turns to gas
Explanation:
Newton's 2nd law of motion:
Force = (mass) x (acceleration)
= (0.314 kg) x (164 m/s²)
= 51.5 newtons
(about 11.6 pounds).
Notice that the ball is only accelerating while it's in contact with the racket. The instant the ball loses contact with the racket, it stops accelerating, and sails off in a straight line at whatever speed it had when it left the strings.

Answer:
k = 4422.35 KN/m
Explanation:
Given that
Frequency ,f= 29 Hz
m = 7.5 g
Natural frequency ω
ω = 2 π f
We also know that for spring mass system
ω ² m =k
k=Spring constant
So we can say that
( 2 π f)² = m k
By putting the values
(2 x π x 29)² = 7.5 x 10⁻³ k
33167.69 = 7.5 x 10⁻³ k
k=4422.35 x 10³ N/m
k = 4422.35 KN/m
Therefore spring constant will be 4422.35 KN/m
one of several competing scientific models that all seem equally successful in explaining the nature of life on Earth
Explanation:
- The theory of evolution is one of the several competing scientific models that all seems to successfully explain the nature of life on earth.
- A theory is usually drawn from careful observation of scientific investigation.
- Theories generally provides explanation into a phenomenon that occurs in nature.
- They are products of careful scientific observations and experiments.
- The theory of evolution is but one of them.
