A car is built from various subsystems. If these subsystems are not working properly it is dangerous because it can cause a serious traffic accident.
<h3>What subsystems do cars have?</h3>
When you're testing the build of a car, you have to check its many subsystems:
- the battery
- the engine
- the cabin
- the thermal-management system
- the gearbox
- the chassis
- the suspension
<h3>Why is a car with damaged subsystems dangerous?</h3>
The subsystems of a car are very important components that allow the proper functioning of the car. These subsystems work synchronously making the car work properly.
However, if one of these subsystems is not working properly it could cause a malfunction that could lead to a traffic accident.

It behaves more like a metal
Explanation:
When an element tends to lose its valence electrons in chemical reactions, they behave more like a metal.
Metals are electropositive.
Electropositivity or metallicity is the a measure of the tendency of atoms of an element to lose electrons.
This is closely related to ionization energy and the electronegativity of the element.
- The lower the ionization energy of an element, the more electropositive or metallic the element is .
Metals are usually large size and prefers to be in reactions where they can easily lose their valence electrons.
When most metals lose their valence electrons, they attain stability.
Non-metals are electronegative. They prefer to gain electrons.

Answer:
i think its B
Explanation:
but check it before do it
Answer:
Explanation:
Charge on uranium ion = charge of a single electron
= 1.6 x 10⁻¹⁹ C
charge on doubly ionised iron atom = charge of 2 electron
= 2 x 1.6 x 10⁻¹⁹ C = 3.2 x 10⁻¹⁹ C
Let the required distance from uranium ion be d .
force on electron at distance d from uranium ion
= 9 x 10⁹ x 1.6 x 10⁻¹⁹ / r²
force on electron at distance 61.10 x 10⁻⁹ - r from iron ion
= 9 x 10⁹ x 3.2 x 10⁻¹⁹ / (61.10 x 10⁻⁹ - r )²
For equilibrium ,
9 x 10⁹ x 1.6 x 10⁻¹⁹ / r² = 9 x 10⁹ x 3.2 x 10⁻¹⁹ / (61.10 x 10⁻⁹ - r )²
2 d² = (61.10 x 10⁻⁹ - r )²
1.414 r = 61.10 x 10⁻⁹ - r
2.414 r = 61.10 x 10⁻⁹
r = 25.31 nm .
