Answer:
Negative
Explanation:
Observe that the object below moves in the positive direction with a changing velocity. An object which moves in the positive direction has a positive velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration).
Answer:
25N
Explanation:
100 - 75 = 25
That should be right if im not dumb...
Answer:
Explanation: find the attached solution below
According to the research, the correct option the eardrum. Sound waves that enter the ear canal are directed to the <u>eardrum</u>, causing it to vibrate.
<h3>What is the
eardrum?</h3>
It is the membrane found in the middle ear of vertebrate animals, separating this sector from the external auditory canal.
When sound waves enter through the external auditory canal, the eardrum vibrates, transmitting its movement to the middle ear through a series of bones and in this way, the pressure change is transformed into a mechanical movement.
Therefore, we can conclude that according to the research, the correct option is the eardrum. Sound waves that enter the ear canal are directed to the <u>eardrum</u>, causing it to vibrate.

Apply Newton's second law to the car's motion:
F = ma
F = net force, m = mass, a = acceleration
Given values:
F = 2500N, a = 3.0m/s²
Plug in and solve for m:
2500 = m(3.0)
m = 830kg
