Mechanical
waves are oscillation of matter, they are important because they all
transfer energy from one place to another. There are 2 types of
mechanical waves. A transverse wave where the particles vibrate
perpendicular to the direction of energy travel and a longitudinal
wave where particle vibrations are parallel to the direction of the
energy transfer.

Old temperature = 283 K.
New temp = 323 K.
(323/283) x (325 kPa) = 371 kPa.
Answer:Gravity
Explanation:Gravity is the force that pulls everything down instead of up because if we didn’t have gravity we would be floating upwards
Answer:
F = MA
Explanation:
OP you didn't give us any examples, but force equals mass times acceleration is Newton's First Law.
Dropping a ball (mass) from the top of a building can show gravity, a form of acceleration.
Answer:
If merging onto an interstate, it is best to merge at the speed of the moving traffic.
Explanation:
As a driver, you cannot always count on the other drivers to see you wanting to merge onto the interstate, and even if they see you, they might not be willing to stop just so you merge, therefore it is best advised to look for a gap in the traffic and merge at the traffic speed.
