Q1. A jeweller working with a heated 44 g gold ring must lower the ring's temperature to make it safe to handle. If the ring is initially at 94 degrees Celsius, what mass of water at 25 degrees Celsius is necessary to lower the ring's temperature to 35 degrees Celsius?
Q2. A clerk moves the box of cans down an aisle by pulling on a rope attached to the box. The clerk pulls with a force of 153 N at an angle of 25.0° with the horizontal. The box has a mass of 35.0 kg, and the coefficient of kinetic friction between box and floor is 0.450. Find an acceleration of the box.
You are driving home from school steadily at 80 for 150. It then begins to rain and you slow to 50. You arrive home after driving 3 hours and 20 minutes.
The resistance of a copper wire of length L meter is 0.1 ohms. If the diameter of the wire is 0.045cm, find out its specific resistance.
If the mass of both weights is 150 gm, the first mass is located 30 north of east, the second mass is located 30 south of east, and the transducer sensitivity is 0.5 volts/Newton, how large a voltage do you expect to measure? Suppose the transducer h..

For safety in climbing, a mountaineer uses a nylon rope that is 69 m long and 1.0 cm in diameter. Whilst supporting a 96-kg climber, the rope elongates 1.4 m. Find its Young's modulus.
A harmonic wave travels in a wire with amplitude 6.05 mm, wavelength 0.451 m, and frequency 462 Hz. What is speed with which the wave travels.
Modeling the optical trap as a Hookean spring, evaluate the trap stiffness using the Boltzmann distribution. Determine the sphere diameter by comparing the Stokes drag and the tweezer force that balances the drag.
