Lunna [17]3 years ago
3 0

Answer:

speed has the dimensions of distance divided by time the SI unit of speed is the metre per second but the most common unit of speed in everyday usage is the kilometre per hour or in the US and the UK miles per hour for air and marine travel the knot is commonly used

If an object falls far enough, it will reach terminal velocity. At this velocity, the force of air
love history [14]

Answer:

The object will contine to fall, but at a constant velocity.  There will be no more acceleration.

Explanation:  When the force of gravity is equal to the reverse force of air resistance, there will will be no net force on the falling obect.  F = ma, and F (net) = 0.  It will continue at the same speed until those forces become imbalanced again (such as when the force pushing up from the ground is greater than the force of gravity pulling it down).  The metric term for this sudden resistance is "crash/bang/clunk/yieouch."

sammy [17]

Answer: you are the person in charge of building a nuclear power plant in Florida. your first choice is to select a site for building the power plant.

Explanation: To find the answer, we need to know more about the nuclear power plants and the criteria to select the site for power plant.

<h3>What you mean by nuclear power plants?</h3>
  • Nuclear power can be defined from the nuclear fission reaction.
  • These power plants will heat the water to produce steam and this steam is used to spin large turbines and thus generates electricity.
<h3>How to select the site for nuclear power plant?</h3>
  • We have to consider the following things,
  • keep distance from populated area.
  • distance from load center.
  • Accessibility to site.
  • Water availability and fuel availability.
  • waste disposal.

Thus, we can conclude that, before building a nuclear power plant, our first choice should be to select a site.

The given function represents the position of a particle traveling along a horizontal line. s(t) = 2t3 − 3t2 − 36t + 6 for t ≥ 0
igor_vitrenko [27]

1) The velocity of the particle is given by the derivative of the position. So, if we derive s(t), we get the velocity of the particle as a function of the time:

v(t)=s'(t)=(2t^3-3t^2-36t+6)'=6t^2-6t-36

2) The acceleration of the particle is given by the derivative of the velocity. So, if we derive v(t), we get the acceleration of the particle as a function of the time:

a(t)=v'(t)=(6t^2-6t-36)'=12t-6
