Answer:
I believe the answer is D: Conductor.
Knowing the amount of force F and the length of time t that force is applied to an object will tell you the resulting change in its momentum ΔP . This is:
F*t = ΔP
ΔP = F*t <em>but ΔP = mv</em>
mv = F*t
v = F*t/m
v = 12000 N × 5 s / 2000 kg
<h3>v = 30 m/s</h3><h2 /><h2>A/ The initial speed of the car was 30 m/s</h2>
Answer:
<em>Fundamental units are the units of the fundamental physical quantities in SI system. They are not formed from other units. There are a total of seven fundamental units such as meter, kilogram, ampere, and second. Derived units are those units that are used for derived quanti</em>ties.

Hope it helps
Those that take the electron from the highest orbital to the lowest (n=1) at this point the energy is -13.6eV. The wavelength is given by c/f. So a large energy (E=hf) gives a short wavelength. Falling from a farther distance out down to the nucleus releases the most energy
An exponential relationship takes the form y = k(a^x), where a and b are constants. Often the value of a turns out to be Euler's number, e = 2.718281828..., because it has the special property that d/dx(e^x) = e^x. Exponential growth might model how the population of a bacterium which divides every 5 seconds increases, and exponential decay might model how the mass of a radioactive isotope sample decreases with time.
Inverse proportion takes the form
An inverse proportion takes the form y = k/x, for a constant k. This kind of relationship might model how the time taken to complete a job varies as the number of workers varies, for example.
We know the formula for density is mass over volume (d = m/v). We therefore see that when mass is considered an arbitrary constant, substitute y = d, k = m and x = v, and we have our inverse proportion.
Intuitively this makes sense. Double the volume for the same mass and the density halves. Quarter the volume for the same mass and the density quadruples.
I hope this helps you :)
