Answer:
C. Chemical reactions may have deteriorated the rubber
Explanation:
A tire ages with time and most of the time this happens due to chemical reactions in the rubber parts. This could happen faster due to heat and sun.
As a tire is deteriorating or aging, a chemical change happens. What happens is that more chemical bonds are going to be produced with time between the molecules. We call this the process of oxidation. This actually bad for the tire, because the rubber would turn out to be stuffs d strong causing the tires thread to separate and also disintegration would occur.
The diagram below shows three types of earthquake waves, labeled A, B, and C at different time intervals. The statement that is correct about the three waves is <span>Wave A and Wave B are absorbed by liquid medium. The answer is letter B.</span>
Volcanic eruptions are caused by earth's internal heat sources.
All the other choices are atmospheric or external earth.
■<em> </em><em>L</em><em>i</em><em>N</em><em>O</em><em>3</em><em> </em><em>=</em><em> </em><em>Lithium nitrate Inorganic compound with the formula LiNO₃. It is the lithium salt of nitric acid. It is obtained from the reaction of lithium carbonate or lithium hydroxide with nitric acid.</em>

■ <em>Fe2O3 = Iron Oxide; It has compounds such as iron chromate (FeCrO4), Iron Phosphate (Fe2P), Iron Sulphide (FeS). Iron oxides in black iron oxide (FeO), red (Fe203) and black (Fe3O4) colors give beige, yellow, brown, red, black colors according to their additive ratios.</em>
■ <em>P3N5</em><em> </em><em>=</em><em> </em><em>Triphosphorus pentanitride is an inorganic compound with the chemical formula P formulaN₅. Containing only phosphorus and nitrogen, this material is classified as a binary nitride. No application has been developed for this material. It is a white solid, but samples often appear colored due to impurities.</em>

The density of oxygen gas is
ρ= 0.0224 m 3
0.0320 kg
=1.43 kg/m 3
From v= B/ρ
we find
B=v 2 ρ
=(317 m/s) 2 (1.43 kg/m 3 )
=1.44×10 5 Pa.
Speed of sound
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 km), or one kilometre in 2.9 s or one mile in 4.7 s. It depends strongly on temperature as well as the medium through which a sound wave is propagating. At 0 °C (32 °F), the speed of sound in air is about 331 m/s (1,086 ft/s; 1,192 km/h; 740 mph; 643 km).
