Answer: ![^{50}_{25}Mn\rightarrow ^{0}_1e+ ^{50}_{24}Cr](https://tex.z-dn.net/?f=%5E%7B50%7D_%7B25%7DMn%5Crightarrow%20%5E%7B0%7D_1e%2B%20%5E%7B50%7D_%7B24%7DCr)
The chromium nucleus will complete the reaction.
Explanation:
The given reaction is a type of radioactive nuclei decay:
Positron emission: It is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. This is also known as
-decay. In this the mass number remains same.
![_A^Z\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e](https://tex.z-dn.net/?f=_A%5EZ%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ-1%7D%5EA%5Ctextrm%7BY%7D%2B_%7B%2B1%7D%5E0e)
Now according to the given reaction:
![^{50}_{25}Mn\rightarrow ^{0}_1e+ ^{50}_{24}Cr](https://tex.z-dn.net/?f=%5E%7B50%7D_%7B25%7DMn%5Crightarrow%20%5E%7B0%7D_1e%2B%20%5E%7B50%7D_%7B24%7DCr)
The chromium nucleus will complete the reaction.
Answer:
45930.52N
Explanation:
Net force = (internal pressure - external pressure)× area of window
Net force = (1.02 - 0.910)atm × 2.03m × 2.03m = 0.11atm × 4.1209m^2 = 0.11 × 101325N/m^2 × 4.1209m^2 = 45930.52N
Answer:
0.125 volts
Explanation:
The induced emf can be sufficient to stimulate neuronal activity.
One such device generates a magnetic field within the brain that rises from zero to 1.5 T in 120 ms.
We need to find the induced emf within a circle of tissue of radius 1.6 mm and that is perpendicular to the direction of the field. The formula for the induced emf is given by :
![\epsilon=-\dfrac{d\phi}{dt}](https://tex.z-dn.net/?f=%5Cepsilon%3D-%5Cdfrac%7Bd%5Cphi%7D%7Bdt%7D)
Where
is magnetic flux
So,
![\epsilon=-\dfrac{d(BA)}{dt}\\\\=2\pi r\times \dfrac{dB}{dt}\\\\=2\pi \times 1.6\times 10^{-3}\times \dfrac{1.5-0}{120\times 10^{-3}}\\\\=0.125\ V](https://tex.z-dn.net/?f=%5Cepsilon%3D-%5Cdfrac%7Bd%28BA%29%7D%7Bdt%7D%5C%5C%5C%5C%3D2%5Cpi%20r%5Ctimes%20%5Cdfrac%7BdB%7D%7Bdt%7D%5C%5C%5C%5C%3D2%5Cpi%20%5Ctimes%201.6%5Ctimes%2010%5E%7B-3%7D%5Ctimes%20%5Cdfrac%7B1.5-0%7D%7B120%5Ctimes%2010%5E%7B-3%7D%7D%5C%5C%5C%5C%3D0.125%5C%20V)
So, the induced emf is equal to 0.125 volts.
