Plants have cell walls, but animals do not because otherwise we wouldn't be able to move.
Newlands - gave idea of law of octaves, he arranged in order of relative atomic mass
Mendeleev - gave idea of periodic table, he arranged in order of relative atomic mass
Answer:
Well, temperature is simply an average measure of the kinetic energy for particles of matter. Another way of putting it would be that temperature simply describes the average vibration of particles. Because the motion of all particles is random, they don’t all move at the same speed and in the same direction.
Q before connected = Q after connected C1V1+C2V2 = (C1+C2) V
C1= 3×10^-6 F
V1= 480v
C2= 4×10^-6 F
V2= 500v
(3×10^-6)×(480) + (4×10^-6)×(500) = (3×10^-6 + 4×10^-6) × V
Simplifying the above, we get:
( 1440× 10^-6) + (2000 ×10^-6) = (7 × 10^-6) × V.
Further simplified as:
3440 × 10^-6 = 7 × 10^-6 × V
Making V the subject
V = 491.43volts
Therefore the potential difference across each capacitor is 491.43v
Here's an unorthodox approach that you might try:
READ each choice and think about it for a coupla seconds !
<span>A) diversity improves an established ecosystem.
No. The results were not an improvement.
B) genetic variation leads to the formation of a new species.
No. There's no mention of genetic variation or new species in the story.
C) the introduction of non-native species upsets a balanced system.
YES ! That's exactly what is described in the story.
D) changing in one part of a system does not affect other parts of the system.
</span>
No. A very great effect on the system is described.
