Item 1
The air temperature is 70 degrees, and the relative humidity is 90%. Which conclusion can be made?(1 point)

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

The air holds little water vapor and is relatively dry.

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

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

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

where’s the list ? the question is incomplete

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
