Atomic size decreases across a period due to an increase in the effective nuclear charge. true or false

Physics
1 answer:
alexgriva [62]3 years ago
3 0

Answer: True

Explanation:

Along a period from left to right  the atomic size decreases because all the electrons are subsequently added to the same shell, also the equal no. of protons are added to the nucleus leading to the increase in the net effective nuclear charge at the constant distance. This leads to the increase in the force of attraction between the (opposite) charged particles which shrinks the atomic size.

This city is the capital of the state of Georgia since 1868 and was burned during the Civil War.
Sphinxa [80]

The correct answer is - Atlanta.

Georgia is a state that has had multiple capitals since the arrival of the first European settlers, changing them very often in accordance to the circumstances. The last one in the row has been Atlanta. This city got the privilege to be the capital of Georgia in 1868 after the Atlanta council applied for it. The US government took everything in perspective, from infrastructure, population, location, and very importantly politics. The political aspect seems to be the case where Atlanta won the case to become capital, as the capital until than, Milledgeville, was still a city where the black population was not welcomed and the racism was still on a very high level.

The acceleration of an object would increase if there was an increase in the
xxMikexx [17]

As per Newton's II law we know that

F_{net} = ma

here we know that

F_{net} = F_{ap} - F_f

so here we will have

a = \frac{F_{ap} - F_f}{m}

so here if we need to increase the acceleration we need to increase the applied force while on increasing the mass or on increasing the friction force the acceleration will decrease.

So here correct answer will be

<em>A) force on the object.</em>
