TA = 80, Ta = 200
TC = 60
Given, y+x = 1
∴ Om solving, x = 71.4 and y = 28.6
Speed of arm a = 28.6 rpm clockwise

RT1 = RT2 exp
For thermistor P,
RT1 = 0.1345
For thermistor Q,
RT1 = 0.264
Then, ratio of resistance of thermistor P to thermistor Q = 0.264/0.1345 = 0.50

Advait Khanna answered • May 26, 2024 |
Explanation:
The sum of the digits of a two-digit number is 12. Let the digits be x and y.
So, x + y = 12
When the digits are reversed, the new number is formed as 10y + x.
Given that the new number is greater than the original number by 54, we can write the equation as:
10y + x - 10x - y = 54
9y - 9x = 54
y - x = 6
Solving the equations:... more

Advait Khanna answered • Dec 20, 2023 |
To solve this problem, we need to determine the energy levels for the 1-D harmonic oscillator. The energy levels for a 1-D harmonic oscillator are given by the equation:
E_n = (n + 1/2) * h * ω
Where E_n is the energy of the nth level, n is the quantum number of the level, h is the Planck's constant, and ω is the angular frequency of the oscillator.

The expected types of gamma ray transition between the following states of odd A nuclei (1) g9/2 are electric dipole (E1) and magnetic dipole (M1) transitions.
In odd A nuclei, the unpaired nucleon can occupy a single-particle state that is typically a high-j orbit such as g9/2. The transition between different single-particle states is driven by the residual strong force, which can cau... more

This takes O(nlogn) time to sort and n time to remove the duplicates. Overall, therefore, this is an O(nlogn) time method.
