HIV INFECTION help This is graded plz plz plz plz HIV infects . Specifically, it infects a type of T cell called a or cell (they are called CD4 cells because of the presence of a CD4 on their membranes).
When HIV enters the body, it seeks out helper T cells by the CD4 protein.
HIV to the cell and releases its material (RNA) into the cell.
The RNA is transformed into . This is called .
The viral DNA is incorporated into the helper T cell .
The helper T cell the viral DNA and makes more HIV .
New viruses are in the helper T cell. They from the helper T cell by off the T cell.
Eventually, the helper T cell is and new viruses other helper T cells.

Pe = 1/2k(x)^2  and .05n/m = .05x10^-9m = x 

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
