Answer:
Densities
Explanation:
When we talk about density, one of the things that come to our mind is actually how heavy something is.
If i have substances that possess different densities, i will notice that i can not really mix them because they will separate and the heavier substance will be at the bottom while the lighter substance will be at the top.
Hence the two substances separated due to difference in density.
Explanation:
It is given that a particle covers 10m in first 5s and 10m in next 3s. so using the equation of motion
Case I
s=ut+

20=10u+25a
4=2u+5a..............(1)
Case 2
In next 3s the particle covers more 10m distance. So
20=8u+

a(8)

5=2u+8a.........(2)
On solving equation (1) and (2)
4=2u+5a
5=2u+8a
a=

Put the value of a in equation (1)
u=

Now to find distance in next 10 s. total time will be 10s
s=

s=28.33m
Distance travelled in next 2 sec
s=28.33−20=8.33m
Answer:
Quick maths
First you find the fafarick and the lalickc and the caprisum and the joinnt
During that final period of time,
his acceleration is
(9 m/s - 5 m/s) / (4 sec) = 1 m/s² .
