Answer:
Competition/collaborate most likely collaboration
Explanation:
Trust me on this this will be the best and least messy way to handle the problem, first try to see if your sister can give away some of her clothes, does your brother really need the room, and can you find a different place to store your drum set if not, competition. Decide a fair competition, something that no one is better at than the other, decide the rules, no cheating, and whatever the out come try to be mature about it, maybe your parents will reward you and your siblings.
Answer:
the fraction of the total energy (Etot) of the cart-spring system is elastic potential energy (Us) is 0.25
the fraction is kinetic energy (K) when the cart is at position x=A/2 is 0.75
Explanation:
the solution is in the attached Word file
Answer:
C. 22 m/s
Explanation:
Ignoring air friction....all of the Potential energy will be converted to Kinetic Energy
mgh = 1/2 m ^v^2
gh = 1/2 v^2
sqrt (2 gh) = v = ~ 22.1 m/s
Answer:
As, we know momentum = mass × velocity that is p = mv
we have momentum (p) = 2 kg m/s
and velocity (v) = 8 m/s
so substitute values in p=mv
2 kg m/s = m × 8 m / s
m = 2 / 8 kg = 0.25 kg
Therefore, mass of substance is 0.25 kg.
2/8 in fractional form.....
