Option a. electronegativity
the measure of the ability of the specified atom to attract electrons in a molecule
Explanation:
this is a chemistry question ???
anyway, it is clearly A, as seatbelts try to counteract the inertia a moving body (our bodies riding in a car) has, when the environment (the car) of this body is suddenly coming to a stop.
this inertia would otherwise try to move the body still forward resulting in a headfirst crash into and often through the windshield. which causes much more damage to the body than the bruises caused by the pressure of the seatbelts against the body counteracting the body's inertia.
but also clearly, all 3 laws play a role.
the force with which the moving body has to deal when smashing into the windshield and potentially then other objects outside the car is described by the second law.
and for any action (crash) there are corresponding reactions (like the conversion of the crash energy into some absorbing reaction : damaged soft and hard tissue in the human body, crumbled car bodies,...).
<span>The answer is (1) chemically combined in a fixed proportion. Elements in a compound are bound by a chemical bond. So, oxygen and hydrogen are bound chemically. Further, their proportion never changes, it is always 1 oxygen atom and 2 hydrogen atoms in water. Thus, elements in a compound are chemically combined in a fixed proportion.Hope this helps.
