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

F = m x $\frac{V}{t}$

V is the velocity

t is the time taken

F = $\frac{75 x 4.4}{3.1}$ = 106.5N

X has successfully been transmitted to your body; you are now infected. All of the following among A-D are possible consequences

Natasha2012 [34]

The complete options to the question includes:

A.You never show any symptoms of disease and there is no sign of the pathogen in your body.

B.You exhibit mild symptoms of disease and the levels of the pathogen in your body are quickly reduced and eliminated.

C.You succumb to the worst effects of the disease but survive due to administration of antimicrobial agents.

D.You never show any symptoms of disease, but the pathogen persists in your body.

E.There are no exceptions, A-D are all plausible outcomes.

Answer: The correct option is A (You never show any symptoms of disease and there is no sign of the pathogen in your body).

Explanation:

Infectious diseases occurs when an individuals system is invaded by pathogenic microorganisms (virus,bacteria,fungi and parasite). These microorganisms may or may not cause disease but this depends on the healthy state of the host. They can also be transmitted from one person to another.

To explain the options why all are plausible outcomes when X has successfully been transmitted into the body except A includes:

B) option B can occur when the immune system of the host is able to combat X.

C.) Option C can occur when antimicrobial is given to suppress the activities of X

D) option D can occur when the individual may become an asymptomatic carrier of X. ( Individual shows no symptoms and signs of disease caused by X but the pathogen is still present in the body).

But option A is not possible as X must be present to show there was a transmission.
