Answer:
C
Explanation:
He was using visual clues to read the signs.
The impulse is equal to the final moment of the wall where the moments and part of the ball from the player
a) mg
=
* ω
b)ω = ![\frac{3g}{2l}](https://tex.z-dn.net/?f=%5Cfrac%7B3g%7D%7B2l%7D)
c)14.7 the magnitude of the initial acceleration of the end B when the string is cut.
<h3>What is Acceleration?</h3>
Acceleration is the rate of change of the velocity of an object with respect to time.
Given
A rod of length 56.0 cm and mass 1.40 kg is suspended by two strings which are 42.0 cm long, one at each end of the rod.
When the string is cut rod rotates about other end.
Let's take momentum equation about that end:
mg*
= Iω [I =
]
a) mg
=
* ω
Angular acceleration:
b)ω = ![\frac{3g}{2l}](https://tex.z-dn.net/?f=%5Cfrac%7B3g%7D%7B2l%7D)
c)Acceleration of end B:
a = lω=
=
a = 14.7 [g=9.8]

Answer: option d: The nucleus of Atom Q is more stable than the nucleus of Atom P.
Explanation:
Atom P is radioactive and disintegrates, it emits beta particles (high speed electrons or positrons) because it is not stable. On disintegration, it forms a stable Atom Q which is non-radioactive and thus it does not disintegrates further.
Thus, the correct option is only d. The nucleus of Atom Q is more stable than the nucleus of Atom P.
