If an object that is 86kg on the moon then that is the answer, 86kg.
Answer:
ΔP = 20000 N s
Explanation:
To solve this problem we use the relation between momentum and moment
I = Δp
let's calculate the momentum
I = ∫F dt
if we use the average force
I = F t
I = 10000 2
I = 20000 N s
therefore with the first equation
ΔP = I = 20000 N s
I think this is because the particles don't know or care about each other,
and they act completely without any peer pressure. The direction in which
any one particle vibrates is completely random, and there is no connection
or influence among the particles. That means that any direction is just as likely
as any other direction for the next vibration, and they all wind up vibrating in
different directions. There is a tiny tiny tiny tiny chance that all of them could
vibrate in the same direction for just an instant; if that ever happened, the rock
would suddenly jump up in the air. That's actually true, but the chance is so tiny
that it hasn't ever happened yet. In fact, the chance is so tiny, that when scientists
do their calculations of particle vibrations, they assume that the chance is zero,
and that makes the calculations simpler.
Answer:
Explanation:
Total =40 miles.
y miles at x miles/hr.
40- y miles at 1.25 x miles/hr.\
We know that
Distance = time x velocity
For y miles
Lets time taken to cover y miles is t
y = x t
t=y/x -----------1
For 40- y
Lets time taken to cover 40- y is t'
40- y = 1.25 x t'
t'=(40-y)/1.25x -----------2
By adding both equation
t+t'=y/x + (40-y)/1.25x
t+t'=(32+0.2y)/x
Now lets time T taken by Marla if she will travel at x miles per hr for entire trip.
40 = x T
T=40/x
So
To find numerical value of above expression we have to know the value of y.
