<u>Answer:</u>
Prior to exercise, a proper warm-up of 10-15 minutes is extremely important to avoid injuries.
- Don't go too hard in the beginning and boost your activity level slowly. A good indication of a proper warm-up is that you feel sweat on your body parts.
- Don't overstretch right in the beginning as it can cause sore in your muscles and joints or stress fractures.
- Take a break if you feel sick or fatigues and use other drinks along with water to replace electrolytes and body fluids.

Explanation:
Según el modelo cinético, las moléculas de gas están en constante movimiento.
La energía cinética promedio de las moléculas del gas depende de la temperatura del gas y de la masa molar del gas.
Si los dos gases ocupan el mismo volumen a la misma temperatura, la energía cinética promedio ahora depende de la masa molar de los gases individuales. Cuanto menor sea la masa molar del gas, mayor será la velocidad media de las moléculas del gas.
El oxígeno gaseoso tiene una masa molar menor que el dióxido de carbono. Por lo tanto, el oxígeno tiene una velocidad molecular promedio mayor que el dióxido de carbono.
Answer:
x = 625 m
Explanation:
To solve this exercise we use the kinematics relations
v² = v₀² - 2 a x
indicate that the train stops therefore its final speed is zero (v = 0)
0 = v₀² - 2a x
x =
let's slow down to the SI system
v₀ = 90 km / h (1000 m / 1km) (1h / 3600 s) = 25 m / s
let's calculate
x =
x = 625 m
