Your bedroom air conditioner blows very cold air at night but only cool air during the day. your bedroom gets lots of direct sunlight all day long. what's the hypothesis and experiment.

because of the sun

Explanation:

at night whenever you get out you usually feel cold and it's dark , that's because the moon doesn't have as much energy as the sun and as you know air conditioners produce the air they get from outside

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

a and b sometimes have a positive value
