D.the amount of time in sun

Well, D. The amount of time in sun doesn't quite make sense yet the rest qualify as a constant or control. Yet, I suppose that under certain circumstances, D can also be considered a constant or control.

How does a logistic growth curve differ from an exponential growth curve?

Paladinen [302]

Firstly models are just predictors, they are not exact models. Exponential growth models are good when populations are small relative to the amount of resources available. ... This is where the exponential model breaks down. The logistic function tries to compensate for this with the carrying capacity.

A force of 150 N is continuously applied to an object with a mass of 11 kg over a distance of 2.5 m.The object slides over a sur

Ivahew [28]

Answer:

Final velocity will be 7.31 m/sec

Explanation:

We have given applied force F = 150 N

Mass of the object m = 11 KG

Distance traveled by the object s = 2.5 m

Coefficient of kinetic friction $\mu _k=0.3$

Acceleration due to gravity $g=9.8m/sec^2$

So frictional force applied on the object $f=-\mu _kmg=-0.3\times 11\times 9.8=-32.34N$

So net force = 150-32.34 = 117.66 N

As work done us equal to $W=Fs$

So work done = $117.66\times 2.5=294.15j$

Now according to work energy theorem work done is equal to change in kinetic energy

So $\frac{1}{2}mv^2=294.15$

$\frac{1}{2}\times 11\times v^2=294.15$

v =7.31 m/sec

So velocity final velocity will be 7.31 m/sec
