  2. BWhich one of the following organisms is not an example of eukaryotic cells?
  3. CWhich one of the following organisms is not an example of eukaryotic cells?
  4. DWhich one of the following organisms is not an example of eukaryotic cells?

Correct answer

C. Which one of the following organisms is not an example of eukaryotic cells?

Step-by-step solution

 K=12mv2, where v=0+at∴K=12m(at)2=12ma2t2 As a=[LT−2]= constant ∴L∝T2∴K=12ma2.L or  K∝L or x.\begin{aligned} & \text{ } K=\frac{1}{2} m v^2, \text{ where } v=0+a t \\ & \therefore \quad K=\frac{1}{2} m(a t)^2=\frac{1}{2} m a^2 t^2 \\ & \text{ As } a=\left[L T^{-2}\right]=\text{ constant } \\ & \therefore \quad L \propto T^2 \\ & \therefore \quad K=\frac{1}{2} m a^2 . L \text{\text{ or } } K \propto L \text{ or } x .\end{aligned}
