Answer:
The minimum uncertainty in its speed is greater than
.
Explanation:
It is given that,
Speed of the particle, 
We need to find the minimum uncertainty in its speed. It can be calculated using uncertainty principle as :

Since, p = mv






So, the minimum uncertainty in its speed is greater than
. Hence, this is the required solution.
Answer:
lamda=10.5m
Explanation:
using the equation of progressive wave.
y=Asin(wt-kx)
comparing the two equations together, we have
kx=0.6x , k=0.6
k=2π/λ
0.6=2*3.142/λ
cross multiply
0.6λ=6.284
divide both sides by 0.6
λ=6.284/0.6
λ=10.47m
approximate
λ=10.5m
Something is reproducing.
As a experiment you could use is The affect of light in plants. A study He can do is maybe about Gravity affects and how it works on weight. Also you can do a all time favorite the Mentos and Diet Coke Experiment.
Hopefully one of these ideas will inspire you!
