The correct answer to the question is: Sound wave.
EXPLANATION:
Before going to answer this question, first we have to understand longitudinal wave.
A longitudinal wave is a mechanical wave in which the direction of propagation of wave is parallel to the direction of particle vibration.
This wave propagates through a medium in the form of compression and rarefaction.
Compression are the regions of high pressure zones where the particles of the medium are closely aggregated to each other.
Rarefaction is the region of low pressure where particles of the medium are not so close to each other as compared to compression.
The longitudinal wave can not propagate in space. It always needs a medium for it's propagation. The medium may be solid, liquid or gas .
For instance, sound wave is a longitudinal wave.
Hence, the correct answer of this question is sound wave which needs a medium for it's propagation.
For Ethernet, if an adapter determines that a frame it has just received is addressed to a different adapter
a. it discards the frame without sending an error message to the network layer
b. it sends a NACK (not acknowledged frame) to the sending host
c. it delivers the frame to the network layer, and lets the network layer decide what to do
d. it discards the frame and sends an error message to the network layer
Answer:
Option A
Explanation:
The nodal address has to match the signal message address for it to function well but if the it doesn't match the nodal receiver address, it disregards it.
Answer:
Force = mass × acceleration
Acceleration:

From first Newton's equation of motion:

Change = v - u:

Answer:
protrons and neutrons
Explanation:
i took a quiz with this question and got it right
The Mass of the car = 782.1 Kg
<h3>What is the mass of the car?</h3>
The mass of the car is calculated as follows:
- Mass = Force/ acceleration
The force on the car = 6570 N
The acceleration of the car, a = 38 - 0/4.5
acceleration = 8.44 m/s²
Mass of the car = 6570/8.44
Mass of the car = 782.1 Kg
In conclusion, the mass of the car is obtained from the acceleration and force on the car.
