The distance is 6+4 which =10 miles. The displacement would be 7.21 miles. This is because you have to use the Pythagorean theorem so a^2 + b^2 = c^2. So 6^2 + 4^2 = 52. Then take the square root and you get 7.21.
Endothermic is when heat is absorbed, so like when ice turns into water, it absorbed heat and energy from the air because now the molecules in the ice started moving faster and more freely to become a liquid state.
Answer:
1.625g
Explanation:
The half - life of a radioactive substance is the time taken for half of it to decay to half of its original composition.
For the given specie, the original composition is 26g and the half life is 15hrs:
At time 0hrs Mass = 26g
For the first half life at time 15hrs Mass = 13g
30hrs Mass = 6.5g
45hrs Mass = 3.25g
60hrs Mass = 1.625g

Answer:
The value is 
Explanation:
From the question we are told that
The mass of the lithium nucleus is 
The radius is 
The speed of the lithium nucleus is 
Given that the lithium nucleus is travelling in a circular path, the magnetic force will be equivalent to a centripetal force so
And ![F_C[tex] is centripetal force mathematically represented as [tex]F_C = \frac{m * v^2}{r}](https://tex.z-dn.net/?f=F_C%5Btex%5D%20is%20centripetal%20%20force%20mathematically%20represented%20as%20%3C%2Fp%3E%3Cp%3E%20%20%20%20%20%20%20%20%20%5Btex%5DF_C%20%3D%20%5Cfrac%7Bm%20%2A%20%20v%5E2%7D%7Br%7D)
So
=> ![F_B = F_C = \frac{9.9932*10^{-27} * [2.40*10^{7}]^2}{ 0.536}](https://tex.z-dn.net/?f=F_B%20%3D%20F_C%20%3D%20%5Cfrac%7B9.9932%2A10%5E%7B-27%7D%20%2A%20%5B2.40%2A10%5E%7B7%7D%5D%5E2%7D%7B%200.536%7D)
