Answer:
D
Explanation: this is why they have so much more energy released
A geologist is studying rock layers in an old river bed, and he finds a fossil of a fish and a horsetail rush in the same rock layer. According to the law of faunal and floral succession, the geologist can assume that the rock containing the fossils may date back as far as the <span>Devonian period</span>.
Answer:
Available options are;
A. validity; high
B. variability; low
C. reliability; low
D. reactivity; high
Answer is C. reliability; low
Explanation:
Normal body temperature is considered to be 37°C (98.6°F); however, a wide variation is seen. Among normal individuals, mean daily temperature can differ by 0.5°C (0.9°F), and daily variations can be as much as 0.25 to 0.5°C. So we can see that the 98 to 106 to 89 degrees shows that the thermometer is not reliable.
For the answer to the question above,
<span>Q = amount of heat (kJ) </span>
<span>cp = specific heat capacity (kJ/kg.K) = 4.187 kJ/kgK </span>
<span>m = mass (kg) </span>
<span>dT = temperature difference between hot and cold side (K). Note: dt in °C = dt in Kelvin </span>
<span>Q = 100kg * (4.187 kJ/kgK) * 15 K </span>
<span>Q = 6,280.5 KJ = 6,280,500 J = 1,501,075.5 cal</span>
<h3>I do think parallel universes exist. There are now some scientific theories that support the idea of parallel universes beyond our own. However, the multiverse theory remains one of the most controversial theories in science.Our universe is unimaginably big. Hundreds of billions, if not trillions, of galaxies(opens in new tab) spin through space, each containing billions or trillions of stars(opens in new tab). Some researchers studying models of the universe speculate that the universe's diameter could be 7 billion light-years(opens in new tab) across. Others think it could be infinite.
u might never know. It might or might not exist in conclusion. </h3>
