¿Cuáles aseveraciones son correctas? * El calor que hace en verano se mide en grados Celsius y la temperatura de nuestro cuerpo se mide en calorías. El calor es sumar toda la energía cinética de las moléculas de un cuerpo y la temperatura es el promedio de la energía cinética. Generalmente en los países ingleses la temperatura se mide en grados Fahrenheit y en México en escala Celsius la escala termométrica del Sistema Internacional de Unidades es la Kelvin y se conoce como Cero Absoluto Para transferir calor por conducción es a través de corrientes de fluidos y por radiación es por contacto.

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
