A 0. 75-kg ball is attached to a 1. 0-m rope and whirled in a vertical circle. The rope will break when the tension exceeds 450

8090 [49]

At the bottom of the circle, the ball is being pulled upward by tension in the rope and downward by its own weight, so that the net force on it is

∑ F = 450 N - (0.75 kg) g = (0.75 kg) a

where a is centripetal acceleration. At this maximum tension, the ball has a maximum centripetal acceleration of

a = (450 N - (0.75 kg) g) / (0.75 kg) = 590.2 m/s²

Then its maximum tangential speed v is such that

a = v² / (1.0 m)

⇒ v = √((1.0 m) a) ≈ 25 m/s

In model 1 a pathogen (virus, bacteria, foreign protein, parasite) has entered the bloodstream of an individual. Draw the symbol

alekssr [168]

There are different kinds of pathogens. The representation of the symbol that stands for the pathogen are;

The helper T-cell is represented like a Circle with the Th wrote inside.

The surface protein on the Th cell is the symbol that looks like this ⊥ or T Th cells.

Pathogens are known to be microorganisms that do invade the bloodstream. It can be easily see among the white cells.

Helper T-cell is known to consist of T-Lymphocytes which monitors the regulation of the immune system. T-cells are regarded as the helper cells that monitors the initial response in front of the pathogen. They includes; TH1, TH2, and TH17.
