Bifați în lista următoare afirmațiile adevărate: Termometrele de exterior folosesc de cele mai multe ori ca lichid termometric mercurul. Prin gaze căldura se propagă prin convecție. Topirea are loc cu absorbție de căldură. Temperatura unui corp este indicată de termometru imediat după realizarea contactului termic. La aceeași variație de temperatură lichidele se dilată mai mult decât solidele. Când două corpuri ajung la echilibru termic temperatura lor este aceeași.

The ballistic pendulum was invented in 1742 by english mathematician benjamin robins. it consists of an initially stationary pendulum that moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. the known variables are the bullet's mass m, the pendulum's mass m, and the height to which the block and bullet swing, determined by the length of the pendulum l and final angle θ. two principles of physics are necessary to solve for the bullet's original velocity. what are these principles? conservation of momentum and newton's third law conservation of energy and conservation of angular momentum grade summary deductions 0% potential 100% conservation of momentum and newton's second law. newton's second law and conservation of angular momentum. conservation of energy and newton's third law conservation of momentum and conservation of angular momentum. conservation of momentum and conservation of energy conservation of energy and newton's second law.

Since the energy was not raising the temperature of the water during these segments, what was the energy used to do instead? your answer must include an explanation of what is happening to the molecules.

An impulse is the product of the on an object and time during which it is applied
