The air temperature is 70 degrees, and the relative humidity is 90%. Which conclusion can be made?(1 point) The air holds little water vapor and is relatively dry.

The amount of water vapor in the air is 90% of what the air can hold.

The dew point temperature is 90% of the air temperature.

The temperature must rise in order for air to become saturated with water vapor.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
