What happens to the structure of an atom when the atom is ionised?​

Physics
1 answer:
Phoenix [80]2 years ago
7 0

Answer: Explanation:

If the number of electrons is equal to the number of protons then the atom is uncharged and is electrically neutral. However, atoms can gain or lose electrons: increasing or decreasing the negative charge. Ionisation is the addition or removal of an electron to create an ion. ..Gaining an electron creates a negative ion.

A sled starts from rest,
Scorpion4ik [409]

Answer:

The acceleration of the sled is 4.6\ m/s^2.

Explanation:

It is given that,

Initial speed of sled is 0 because it was at rest.

It is placed at an angle of 28° on a frictionless hill.

We need to find the acceleration of the sled. It is placed at an incline. It means that the acceleration of the sled is given by :

a=g\sin\theta\\\\a=9.8\times \sin(28)\\\\a=4.6\ m/s^2

So, the acceleration of the sled is 4.6\ m/s^2.

Is the gravitational force between the two objects attractive, repelling, or both? Explain how you know
puteri [66]

Answer: attractive

Explanation:

According to Newton's law of Gravitation, the gravitational force F exerted between two bodies of masses m1 and m2  and separated by a distance r  is equal to the product of their masses and inversely proportional to the square of the distance:

F=G\frac{(m1)(m2)}{r^2}  

Where:

G is the Gravitational Constant

m1 and m2 are the masses of the objects

r  is the distance between the objects

It should be noted: this force is a central force and is attractive.

Chintu and raven build a roccket, which moved from the earth to about 86m into the shy. It tales 3.7 seconds to reach the rocket
vaieri [72.5K]

   Speed = (distance covered) / (time to cover the distance)..

From the ground to the highest point,
the rocket's AVERAGE speed is

                     (86 m) / (3.7 sec)  =  23.2 m/s  (rounded) .
