Physical Principles & Numerical Solution
To find the angular speed (\( \omega \)) of an object moving in a circle, we use the formula:
\(\omega = \frac{v}{r}\)
Given:
- Linear speed (\( v \)) = 10 m/s
- Radius (\( r \)) = 4 m
Substituting the values into the formula:
\(\omega = \frac{10 \, \text{m/s}}{4 \, \text{m}} = 2.5 \, \text{rad/s}\)
The angular speed is \(\omega = 2.50 \, \text{rad/s}\)

Verified Correct Answer: Option A
Physical Principles & Numerical Solution
Final Temperature = \(\frac{m_1 T_1 + m_2 T_2}{m_1 + m_2}\)
where m\(_1\) and m\(_2\) are the weights of the water in the first and second containers.
T\(_1\) and T\(_2\) are the temperatures of the water in the first and second container.
Given Final temperature = 50^\circC;
Let m\(_1\) = b, then m\(_2\) = 2b.
T\(_1\) = t; T\(_2\) = 30^\circC
\(\therefore 50 = \frac{b(t) + 2b(30)}{b + 2b}\)
\(50 = \frac{bt + 2b(30)}{3b}\)
\(50(3b) = bt + 2b(30) \implies 150b = b(t + 60)\)
\(150 = t + 60 \implies t = 150 - 60 = 90^\circC\)
