TS EAMCET Mock Test - 8 - Question 1

The radionuclide 56Mn is being produced in a cyclotron at a constant rate P by bombarding a manganese target with deutrons. 56Mn has a half life of 2.5 hours and the target contains large number of only the stable manganese isotope 55Mn. The reaction that produces 56Mn is:

55Mn+d→56Mn+P

After being bombarded for a long time, the activity of 56Mn becomes constant equal to 13.86×10s−1. (Use ln2 = 0.693; Avogadro number = 6×1023 atomic weight of 56Mn = 56gm/mole)

Q. After a long time bombardment, number of 56Mn nuclei present in the target depends upon 
(a) The number of 56Mn nuclei present at the start of the process 
(b) Half life of the 56Mn
(c) The constant rate of production P

In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A):Two bodies 1 and 2 exerting forces on each other.Force exerted on the body 1 by body 2 is F → 12 and that exerted on the body 2 (by body 1) is F → 21 . Then F → 12 = − F → 21 .
Reason(R):Force F → 12 is of action and force F → 21 is of reaction.

Detailed Solution for TS EAMCET Mock Test - 8 - Question 7

Assertion is true as acc to Newton second law Fab=-Fba i.e every action has an equal and opposite reaction. Since force is a Vector quantity opposite direction is to be indicated by negative sign. So in question assertion is true but in reason the force of reaction is not in opposite direction because negative sign is not there. So reason is false.

A 5 μF capacitor is fully charged across a 12V battery. It is then disconnected from the battery and connected to an uncharged capacitor. If the voltage across the capacitor becomes 3V, the capacitance of the uncharged capacitor is
Detailed Solution for TS EAMCET Mock Test - 8 - Question 9
C1 * V1 = Q1. [Eq. 1]
Where, C1 = 5uF, V1= 12V.
This means capacitor 1 is able to gather up to 60uC of charge; before the circuit reaches voltage equilibrium and no more current flow is possible.
Now we transfer this bank of charge to another circuit with an uncharged capacitor, C2, which absorbs enough charge and leaves the circuit in equilibrium at 3V.
i.e. V2 = 3V
At 3V C1 can retain a charge of 15uC [using Eq. 1]. This means C2 most possess the remaining 45uC[Q2] of charge; at 3V[V2].
C2 = Q2/V2
C2= 45uC/3V
C2= 15uF

Let (r + 1)th term be the constant term in the expansion of .
Then, Tr + 1 = 15Cr (x3)15 - r . (-1/x2)r is independent of x.
Or Tr + 1 = 15Cr x45 - 5r (-1)r is independent of x.
