Explanation:

It is known that both sodium (Na) and cesium (Cs) are group 1 elements. This group is also known as alkali metal group.

Both Na and Cs has one valence electron but size of cesium is much larger than the size of sodium.

This means that larger is the size of atom farther away will be the valence electron(s) from the nucleus. Hence, there will be very less or no force of attraction between the nucleus and valence shell.

Therefore, it will be much easy for a larger atom to lose its valence electron. So, the atom will become more reactive in nature.

Thus, we can conclude that Cs is more reactive than sodium metal.

How do the circulatory system and the respiratory system work together?
mezya [45]
The circulatory system tends to pump blood around the whole body, while the respiratory system tend to facilitate the exchange of gas in the body so then the blood will look totally fresh. In simpler terms, the heart is connected to the lungs through the means of arteries and veins.

Jack applies a force of 30 and move 90 kg box. What is the acceleration of the box?
Scilla [17]

Explanation:

Given , F = 30N and mass m = 90kg

°•° F = ma

=> a = F/m

=> a = 30/90

=> a = 1/3m/s^2

Within which matter does light travels the fastest? Solid liquid or gas
exis [7]

Answer:

Light travels fastest in gas

Explanation:

Light is likely to hit a molecule and then gets re-emitted, extending the amount of time the light take to get through a certain distance of the medium

Gas > liquid > solid

After driving a portion of the route, the taptap is fully loaded with a total of 25 people including the driver, with an average
loris [4]

Answer:

0.4455 m

Explanation:

g = Acceleration due to gravity = 9.81 m/s²

Total mass is

m=62\times 25+15\times 3+5\times 3+25\\\Rightarrow m=1635\ kg

Here the spring constant is not given so let us assume it as k=36000\ N/m

Here, the forces are balanced

mg=kx\\\Rightarrow 1635\times 9.81=36000\times x\\\Rightarrow x=\dfrac{1635\times 9.81}{36000}\\\Rightarrow x=0.4455\ m

The springs are compressed by 0.4455 m
