In comparison to their neutral parent atom, anions are bigger and cations are smaller.

<h3>Why are anions of the same element larger than their neutral counterparts?</h3>

They are forced to spread out more due to electron-electron attraction. They can get closer to each other because there is less electron-electron repulsion.

Because cations contain fewer electrons than their parent atoms while maintaining the same nuclear charge, they are always smaller than those atoms. The leftover electrons are therefore held by the protons in the nucleus more tightly, and as a result, their radii are less than those of the parent atoms. With anion, this is the exact opposite.

Pretend you (80 kg) are making repairs on the outside of the International Space Station. You are floating 20 meters away from t

djyliett [7]

Answer:

32 seconds

Explanation:

m1 = 80 kg

m2 = 10 kg

v2 = 5m/s

According to the property of conservation of momentum, assuming that both you and the bag are stationary before the safety rope comes lose:

$m_{1} v_{1} =m_{2} v_{2} \\80v_{1} =10*5 \\v_{1} = 0.625\ m/s$

Since the space station is 20 meters away, the time taken to reach it is given by:

$t = \frac{20}{0.625}\\t=32\ s$

It takes you 32 seconds to reach the station.

Two people carry a heavy object by placing it on a board that is 2.2 meters long. One person lifts with a force of 750 N at one

stiks02 [169]

Answer:

This means that the center of mass is locates 0.72m from the 750N force

Explanation:

Since the board is 2.2m long, that will be the length of the board.

Let the center of mass of the body be hinged at the center using a knife edge as shown in the diagram attached.

Let x be the distance from the 750N force to the knife edge and the distance from the 360N force to the knife edge be 2.2-x

Using the principle of moment which states that the sum of clockwise moment is equal to the sum of anti clockwise moment.

Moment = force × perpendicular distance

For ACW moment;

Moment = 750×x = 750x

For the CW moment;

Moment = 360 × (2.2-x)

Moment = 792-360x

Equating ACW moment to the clockwise moment we have;

750x = 792-360x

750x+360x = 792

1110x = 792

x = 792/1110

x = 0.72m

This means that the center of mass is locates 0.72m from the 750N force
