To be careful towards what you do.
Answer:
15000000 m
Explanation:
From the question,
Speed (S) = Distance(d)/Time(t)
S = d/t....................... Equation 1
Make d the subject of the equation
d = St..................... Equation 2
Given: S = 50 km/s = 50000 m/s, t = 5 minutes = 5*60 seconds = 300 seconds
Substitute these values into equation 2
d = 50000(300)
d = 15000000 m
Hence the skier travels 15000000 m
We have that all except Uranium is Stable
From the question we are told
Classify the following nuclei into stable or unstable.
- Generally a nuclei is made up of Neutrons and Protons
- A stable nuclei is one with its Protons and Neutrons equal or Very close
Generally the equation for Stable Nuclei is mathematically given as
n=p
Therefore
For U
P=92
N=238-92
N=146
Therefore Unstable
For N
P=7
N=9
Therefore Stable
For Be
P=4
N=6
Therefore Stable
For Ne
P=10
N=10
Therefore Stable
For Al
P=13
N=14
Therefore Stable
For Ar
P=18
N=21
Therefore Stable
For Ni
P=28
N=36
Therefore Stable
For O
P=8
N=7
Therefore Stable
For He
P=2
N=2
Therefore Stable
For Sc
P=21
N=20
Therefore Stable
For Li
P=3
N=3
Therefore Stable
