Answer:
If this helps, to work out the kinetic energy the formula is K (stands for kinetic energy) = 1/2 (half of) mass and velocity. So the answer is 450 joules.
Explanation:
A hypothesis about what might happen in the lab might be 'oxygen will react with hydrogen to form water molecules'.
<h3>What is a hypothesis?</h3>
A hypothesis is a given explanation of a particular scientific question emerged by observing the real world.
Hypotheses are explanations that must be tested (either confirmed or rejected) by using the scientific method.
In conclusion, a hypothesis about what might happen in the lab might be 'oxygen will react with hydrogen to form water molecules'.

T = 3 h = 3 x 3600s = 10800s
d = 100 x 10800 = 1080000km to The east.
-- Speed = (distance) / (time to cover the distance) = 840/2.5 = 336 m/s
-- Frequency = (speed) / (wavelength) = 336/0.70 = 480 Hz.
