Answer:
Distance is the whole travel from A to B and B to C.
While, displacement is the shortcut directly from A to C.
Answer:
1. :uniformly accelerated motion
2. .0m/s
Answer: the correct answer is 7.8026035971 x 10^(-13) joule
Explanation:
Use Energy Conservation. By ``alpha decay converts'', we mean that the parent particle turns into an alpha particle and daughter particles. Adding the mass of the alpha and daughter radon, we get
m = 4.00260 u + 222.01757 u = 226.02017 u .
The parent had a mass of 226.02540 u, so clearly some mass has gone somewhere. The amount of the missing mass is
Delta m = 226.02540 u - 226.02017 u = 0.00523 u ,
which is equivalent to an energy change of
Delta E = (0.00523 u)*(931.5MeV/1u)
Delta E = 4.87 MeV
Converting 4.87 MeV to Joules
1 joule [J] = 6241506363094 mega-electrón voltio [MeV]
4 mega-electrón voltio = 6.40870932 x 10^(-13) joule
4.87 mega-electrón voltio = 7.8026035971 x 10^(-13) joule
Answer:
The germline (the gametes)
Explanation:
Mutations are permanent changes in the DNA sequence. They can occur randomly, from mistakes during DNA replication, or as the result of external factors like UV radiation.
For these mutations to be passed on to the next generation, they must be present in the DNA of the gametes(i.e. the egg and sperm cells). This is because this is the DNA that goes on to make the offspring in the next generation following fertilisation.
If mutations are present in somatic cells (i.e. cells other than the gametes), they are not passed on to the next generation. For example, if someone gets mutations in their skin cells as a result of exposure to UV rays, this will not be passed on to their children.
Answer:
Explanation:
It is given that,
Speed of P- waves, v = 9 km/s = 9000 m/s
The density of rock is about 
We need to find the average bulk modulus of Earth's crust. Let it is given by B. So,
So, the bulk modulus of the Earth's crust is 
.
