Answer:
Density
Explanation:
Waves are periodic disturbances that travel in a medium by carrying energy without carrying matter.
There are two types of waves:
- Mechanical waves: these are produced by the vibrations of the particles in a medium. An example of mechanical waves are sound waves. Mechanical waves can only propagate through a medium, while they cannot travel in a vacuum.
- Electromagnetic waves: these consist of the oscillations of electric and magnetic fields in a direction perpendicular to the propagation of the wave. These are the only type of waves that can travel in a vacuum, since they do not need a medium.
The speed of a wave is the speed at which the wave propagates through the medium / the vacuum.
For mechanical waves, the speed of a wave in a solid material is given by
where
B is the bulk modulus of the medium
is the density of the medium
Therefore, from the formula we see that the wave speed depends on the density of the medium, while the other quantities (volume, electric charge) are not involved.
For liquids and gases, the wave speed is obtained through a different formula, however it still depends on the density of the material. So the correct answer is
a) Density
400 horsepower is produced by 2023 z's 3. 0-liter twin-turbo 6-cylinder engine.
<h3>What is horsepower?</h3>
The power an engine produced is referred to as horsepower. In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minute, i.e., the force required to lift a mass of 33,000 pounds off the ground in a single motion for one minute.
The new Z's 3.0-liter twin-turbo V6 engine produces 400 horsepower and 350 pound-feet of torque. This is 68 horsepower and 80 lb-ft more than the previous 370Z. The 6-speed manual transmission that comes standard or the optional 9-speed automatic transmission with paddle shifters are both paired with this one engine option.

Answer:
The SI system, for this reason, is also called the MKS system. CGS system: On the other side or the second self-consistent system uses centimetres, grams and seconds for length, mass and time.
Explanation:
(a) The average speed must you have for the second half of the trip to meet your goal is 8 km/h.
(b) The value obtained (8 km/h) is not reasonable for the second half of the distance since the first half is 48km/h.
<h3>
What is average velocity?</h3>
Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.
average velocity = total distance / total time
v = (d)/(0.5d/v₁ + 0.5d/v₂)
where;
- v is the average velocity
- v₁ is the average velocity during the first half
- v₂ is the average velocity during the second half
90 km/h = (d) / (0.5d/48 + 0.5d/v₂)
90(0.5d/48 + 0.5d/v₂) = d
0.9375d + 0.5d/v₂ = d
d(0.9375 + 0.5/v₂) = d
0.9375 + 0.5/v₂ = 1
0.5/v₂ = 0.0625
v₂ = 0.5/0.0625
v₂ = 8 km/h
Thus, the average speed must you have for the second half of the trip to meet your goal is 8 km/h.
The value obtained (8 km/h) is not reasonable for the second half of the distance since the first half is 48km/h.
