It must exist in p<span>lasma state.</span>
Answer:
speed of light simulating traveling at the speed of light. Speed of light, speed at which light waves propagate through different materials. In particular, the value for the speed of light in a vacuum is now defined as exactly 299,792,458 metres per second
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium
b. A Boeing 747 airplane
Explanation:
The Boeing 747 airplane will have the most inertia of all. Inertia is the tendency of an object to remain at rest or uniform motion.
- Newton's first law of motion is also regarded as the law of inertia.
- It states that "an object will remain at rest or uniform motion motion unless acted upon by an external force".
- A body that has a large mass will be more resistant to any external force that acts on it.
- The Boeing 747 has the most mass of all and will have the most inertia.

Assuming Earth's gravity, the formula for the flight of the particle is:
<span>s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160. </span>
<span>This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2. </span>
<span>Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet. </span>
