A condition in which self molecules are treated as non-self is the best definition of autoimmune disease.
<u>Option: D</u>
<u>Explanation:</u>
An autoimmune illness is a disorder wherein the immune system to attack the body inappropriately. The immune system usually watches off germs such as bacteria and viruses. If it detects these foreign invaders, an army of fighter cells is sent out to strike them.
The very general autoimmune diseases are like Systemic lupus erythematosus (lupus), Rheumatoid arthritis, IBD, multiple sclerosis (MS), type 1 diabetes mellitus, etc. Autoimmune disorders do not trigger sepsis, but there is a greater chance of developing complications in individuals with other forms of autoimmune disorders, which can activate sepsis.
The BUS will have the highest kinetic energy, while the BICYCLE will have the lowest kinetic energy.
This is because if an object has a greater mass, the kinetic energy of the object also increases. Kinetic energy depends on mass and velocity (KE=1/2*m*v^2) and since the velocity of these vehicles are the same, the mass is the only difference
The
horizontal component of an angular distance can be calculated by multiplying the
distance with the cosine of the angle, Dx = D * cos θ
While
the vertical component is calculated by multiplying the distance with the sine
of the angle, Dy = D * sin θ
The
resultant displacement can then be obtained using the formula for hypotenuse
and summations of each component:
R^2
= (summation of Dx)^2 + (summation of Dy)^2
summation
of Dx = 600 * cos47 + 500 * cos128 + 300 * cos209 + 400 *
cos(-77) = -71.0372
summation of Dy = 600 * sin47
+ 500 * sin128 + 300 * sin209 + 400 * sin(-77) = 297.6267
<span> Note: you have to draw the lines to correctly
determine the angles</span>
R^2 = (-71.0372)^2 + 297.6267^2
R = 306 m
The resultant angle is:
tan θ = Dy / Dx
θ =
tan^-1 (297.6267 / -71.0372)
θ =
103˚ = [N 13˚ W]
Therefore
displacement is 306 m <span>[N 13˚ W].</span>
Answer:
<em>the minimum speed that the ball must have so that the cord does not become slack is</em> <em>2.02 m/s.</em>
<em></em>
Explanation:
In order to avoid slack, the centripetal force of the ball must equal its weight at the top of the circle. Therefore,
F_c = F_g
m v² / r = m g
v² = g r
v = √[g r]
v = √[(9.8 m/s²)(0.417 m)]
<em>v = 2.02 m/s </em>
Therefore,<em> the minimum speed that the ball must have so that the cord does not become slack is</em> <em>2.02 m/s.</em>
