<h2>
Answer: Indivisible</h2>
Explanation:
<u>The first atomic model was the one proposed by Jhon Dalton</u>, according to which it is postulated that:
<em>"Matter is made up of </em><u><em>indivisible</em></u><em>, indestructible and extremely small particles called atoms." </em>
That is, the<u> atom is a solid and indivisible mass. </u>
<u>
</u>
However, at the end of 19th century the physicist <u>J.J. Thomson began experimenting with cathode ray tubes</u> and found out that<u> atoms contain small subatomic particles with a negative charge</u> (later called electrons).
This means<u> the atom was not indivisible as Dalton proposed.</u> So, Thomson developed in 1904 a new atomic model that was called the <u>raisin pudding atomic model.</u>

Therefore:
<h2>J. J. Thomson’s experiment disproved the theory that an atom <u>
is indivisible</u></h2>

Explanation:
Answer:
impulse will be equal to 1.969 N-s
Explanation:
We have given mass of the golf ball m = 60.8 gram = 0.0608 kg
Horizontal speed of the ball is v = 32.4 m/sec
We have to find the impulse of the golf ball
We know that impulse is equal to momentum of the object
So we have to find the momentum of the object
Momentum of the object is equal to product of mass of the object and speed of the object
So
As momentum is equal to impulse so impulse will be equal to 1.969 N-s
Answer:small barrel gun
Explanation:
Given
Muzzle velocity of bullet is greater in short barrel gun as compared to larger barrel gun
acceleration is given by change in velocity with respect to time
In case of short barrel bullet time taken by bullet to reach its muzzle velocity is less therefore acceleration of small barrel bullet is more compared to long barrel bullet.
