What are two things that can be done to maximize the chances of recovering parasites from a fecal smear?

RideAnS [48]

<span>Sedimentation - uses solutions of lower specific gravity than the organisms, which concentrated in the sediment. This technique is recommended for general diagnostic laboratories because it is easy to perform and less prone to technical errors.

Flotation - this technique uses solutions of higher specific gravity than the parasitic organisms so the organisms float and the debris sinks producing a cleaner material while the disadvantage is that walls of cysts and eggs collapse that may blocking its identification.<span>

terry physics pushes a 75kg lab cart so that is accelerates from rest with a velocity of 4.4m/s in 3.1 secounds. what is the for

svetlana [45]

106.5N

Explanation:

Given parameters:

Mass of cart = 75kg

Velocity = 4.4m/s

time taken = 3.1s

Unknown:

Force = ?

Solution:

To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".

F = m x a

F = force on body

m = mass of body

a = acceleration of the body

But we know that acceleration is the change in velocity with time of a body;

a = $\frac{change in velocity }{time}$
