Objects and substances in motion have Kinetic Energy.
Explanation:
Kinetic Energy is the motion of objects, substances, molecules, atoms .
Whenever an object starts to move, it is in motion. Kinetic Energy is generated, when the object moves and its potential energy gets dropped with the movement. Kinetic Energy is found in every object that moves.
The Kinetic Energy of an object depends both on its mass and its speed. Kinetic Energy increases as mass and speed are increased.
Example: By using the wind flow from wind turbines, the Kinetic energy in the wind can be transformed to generate electricity by using generators.

It is use to set again and conceal data by giving the data a different form. It restores the device to the original manufacture's settings.
Answer:
El neumático soportará una presión de 1.7 atm.
Explanation:
Podemos encontrar la presión final del neumático usando la ecuación del gas ideal:
En donde:
P: es la presión
V: es el volumen
n: es el número de moles del gas
R: es la constante de gases ideales
T: es la temperatura
Cuando el neumático soporta la presión inicial tenemos:
P₁ = 1.5 atm
T₁ = 300 K
(1)
La presión cuando T = 67 °C es:
(2)
Dado que V₁ = V₂ (el volumen del neumático no cambia), al introducir la ecuación (1) en la ecuación (2) podemos encontrar la presión final:
Por lo tanto, si en el transcurso de un viaje las ruedas alcanzan una temperatura de 67 ºC, el neumático soportará una presión de 1.7 atm.
Espero que te sea de utilidad!
