OH Cool! So.. 9.8 * 90 = 1/2 * 20 ^2 + 9.8 * hc
mode of building, construction, or organization; arrangement of parts, elements, or constituents: a pyramidal structure. something built or constructed, as a building, bridge, or dam. a complex system considered from the point of view of the whole rather than of any single part: the structure of modern science.
Waves that are in phase constructively interfere to create bright bands was observed in the double-slit experiment.
<h3>What is Interference?</h3>
This is defined as the phenomenon which occurs when two waves meet while traveling along the same medium.
A wave when in phase undergoes constructive interference while out of phase undergoes destructive interference which is why option C was chosen as the most appropriate choice.

Answer:
Explanation:
Let assume that cooling water works under a pressure of 1 atmosphere. The time required to boil half of the water is determined by the First Law of Thermodynamics:
Answer:
450 kJ
Explanation:
Q = mCΔT
where Q is heat (energy),
m is mass,
C is specific heat capacity,
and ΔT is the temperature change.
Q = (1.2 kg) (4180 J/kg/°C) (100°C − 10°C)
Q = 451,440 J
Q ≈ 450 kJ
