Rate of change = (amount of change) / (time for the change)
Amount of change = (temp at the end) minus (temp at the beginning)
Amount of change = (70°F) minus (62°F) = 8°F
Time for the change = (time at the end) minus (time at the beginning)
Time for the change = (1200 - 0800) = 4 hours
Rate of change = (8°F) / (4 hours)
Rate of change = 2°F per hour
It is a nuclear reaction, where the nucleus of an atom splits into smaller parts
Answer:
Both erg and Joule are units of Energy in the CGS and S.I system respectively.
Joule and erg can also be written as (kg m2/s2) and (g cm2/s2) respectively.
Explanation:
1 Joule = 107 erg ⇒ 107 kg m2/s2.
Light<span> refracts whenever it </span>travels<span> at an angle into a substance with a </span>different<span>refractive index (optical density). This change of direction is </span>caused<span> by a change in speed. For example, when </span>light travels<span> from air into water, it slows down, causing it to continue to travel at a </span>different<span> angle or direction.</span>
At a definite point, the bridge would begin oscillating to the matching rhythm as that
of the marching footsteps.
This oscillation would touch a determined peak when the bridge can
no longer tolerate its own
power and later collapses. So, soldiers are
systematic to break their steps
while passing a bridge.
