Answer: the green color of a leaf
Explanation: because the other things are physical changes of a plant that don't get passes down to offspring
Answer:
R/l = 0.25925 Ω / m
Explanation:
Ohm's law says that the potential difference is proportional to the product of the resistance by the current
V = I R
R = V / I
In this case, since we have two lengths, we can have two lengths, we can find the resistance for each
L = 5 m
R = 7.70 / 5.47
R = 1,408 Ω
L = 10 m
R = 7.70 / 3.25
R = 2,369 Ω
We can make a direct proportions rule (rule of three) to find the resistance per unit length
For L = 5 m
R/l = 1,408 / 5
R/l = 0.2816 Ω / m
For L = 10 m
R/l = 2,369/10
R/l = 0.2369 Ω / m
We can see that the value is similar that differs from the second decimal place, in this case the value for the longer re wire is more accurate because it has a lower joule effect.
One way also to find the average value
R/l = (0.2816 + 0.2369) / 2
R/l = 0.25925 Ω / m
Answer:
Potential energy only
Explanation:
at the top of its swing the pendulum stops moving , (therefore it has no KINETIC energy) thus all of the energy is stored as potential energy.
Answer:
Momentum is the product of a moving object's mass and velocity . ... When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It is true for all collisions.
