Answer:
Repeated experimentation introduced new discoveries.
Explanation:
Science is not a static body of knowledge, scientific theories change as new evidence emerges from repeated experiments.
For many years, the wave theory of light was generally held by almost all scientists.
Further experiments such as photoelectric effect and Compton effect lent credence to the the particle theory of light, hence the answer
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).

Chlorine-36 has been widely used for dating old groundwater.
<span>The ionic form of Chlorine is Chloride. Chloride helps maintain the body's fluid balance. It is a component of hydrochloric acid (HCl acid) in your stomach which helps good digestion. It is also an aide to maintain the acid-base balance of your body. Among the choices given, letter C is not a function of chloride. Excess or too much dietary intake of chloride causes hypertension.</span>
