Explanation:
I don't think it matters while taking a shower, however, while using the restroom, it is especially encourgaed to wipe front to back. The reasoning behind this is to prevent UTI's that are transferred by fecal particles and bacteria from the anus into the vagina. Hope this helps:)
Answer:
1) Because of the size and time the sound wave moves, an echo is typically transparent and easy to discern. Since reverberations typically don't have enough distance or time to fly, they will pile up on top of each other, making it impossible to understand.
People will detect an echo if the distance between the source of the sound and the reflected body is greater than 50 feet. When a sound wave is bounced off a nearby surface, it may create a reverberation.
2) The speed of sound in hot air is more than that in cold air because air molecules are traveling faster in hot air.

Answer:
Their change in momentum is the same in magnitude and opposite in direction
Explanation:
The momentum of an object is defined as:
where
m is the mass of the object
v is the velocity of the object
Therefore, the change in momentum of an object is
where is the change in velocity.
During a collision, the force experienced by an object is equal to the rate of change of momentum:
where is the duration of the collision.
According to Newton's third law of motion, the force exerted by vehicle 1 on vehicle 2 during the collision is equal (and opposite) to the force exerted by vehicle 2 on vehicle 1, so
Which means
And since the duration of the collision is the same for the two vehicles, this becomes
Yeah!! It is better to decrease the speed of the vehicle so the ejection of gases would happen in slow manner.... then you can save your gasoline
