Answer:
C)T
Explanation:
The period of a mass-spring system is:
As can be seen, the period of this simple harmonic motion, does not depend at all on the gravitational acceleration (g), neither the mass nor the spring constant depends on this value.
There are MANY of them, but I shall name the three that I find dangerous.
1- We would run out of energy, which could happen eventually if we do not use this resource wisely.
2- We could get a-lot of diseases/illnesses because WE ourselves are made of electricity, and if we take up too much, we could get sick.
3- We would rely on electricity too much, and later if it runs out, we would die....literally. <span />
Answer:
there isn't anything else posted to the question when you ask a question put a picture or write it out so people can see it
Explanation:
<span>a) M is the big one
m is the little one
v is the speed of each of them when they impact
V = speed of mii after collision
Conservation of momentum
Mv – mv = mV
Conservation of energy
1/2Mv^2 + 1/2mv^2 = 1/2 mV^2
This pair simplify to give
M = 3m
V = 2v
So m = 0.21kg
and h = 4 . 2.7 = 10.8 m</span>Source(s):<span>Old teacher</span>
