Determine the period of oscillations in Trial I. We recommend starting at the equilibrium position. Even though the video is shot at 30 frames per second, it may be challenging to find the frame where the "X" is exactly lined up with the equilibrium. Do your best. Did we mention that you need to find the period for Trial I?

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.

An electric kettle is made out of stainless steel, weighs two pounds (when empty) and is equipped with a heating element that consumes 2 kw of electricity. assuming that the water and the kettle are at the same uniform temperature at any moment of time, calculate the shortest possible time to bring 2 quarts of water from room temperature to the onset of boiling
