Smoking increases ____ levels in the blood, thus increasing the possibility of unwanted clotting.

1 answer:

7 0

It could increase homocysteine levels—and when these levels are raised, it could make the inner linings of the arteries to be damage and it usually occurs because of unwanted clotting increasing in a person’s body of which could cause factor or contributors making the increase, such as like smoking—this increases, the unwanted blood clots in the body which makes these levels increase, producing unwanted defects.

What is the y component of a vector defined as 12.2m at 81.5°?

sergejj [24]

Answer:

Explanation:

This is a displacement vector since it is defined in terms of distance (meters, to be exact). The way you find the y-component is

$V_y=Vsin\theta$ which says that you multiply the magnitude of the vector (its length) by the sin of the direction (the angle):

$V_y=12.2sin(81.5)$ and get

$V_y=$ 12.1 m

During a race the dirt bike was observed to leap up off the small hill at A at an angle of 60^o with the horizontal. If the poin

Answer:

Velocity is equal to $27.3$ feet per second and time is equal to $1.4668$ seconds

Explanation:

Given

The horizontal distance traveled by dirt bike before landing $= 20$ feet

Angle of flight $= 60$ degree

As we know that Horizontal distance (H) is equal to

$= H_0 + V_0 * t\\$

Where $H_0$ is the initial horizontal distance

$V_0$ is the velocity with which the bike is travelling in horizontal direction

and $t$ is the time in seconds

Substituting the given values, we get -

$H = H_0 + v*t\\20 = 0 + v * cos \theta * t\\20 = v * cos 60 * t\\t = \frac{20}{v * cos 60} \\t = \frac{40}{v}$

Now distance traveled in vertical direction is equal to

$Y = Y_0 + v_0 * t + \frac{1}{2} a * t^2$

here acceleration will be equal to acceleration due to gravity which is equal to $- 32.2 \frac{ft}{s^2}$ . It is negative as its is acting in upward direction

Thus,

$Y = 0 + v * sin 60 + \frac{1}{2} * (-32.2) * (\frac{40}{v} )^2\\0 = 0 + 0.866 v + \frac{-25760}{v^2} \\0.866 v = \frac{-25760}{v^2}\\v^3 = \frac{-25760}{0.866} \\v = 27.3$

Velocity is equal to $27.3$ feet per second and time is equal to $1.4668$ seconds

KFC has engineered chickens that do not have beaks and double breast

True [87]

I don't think so.

Before I can accept that rumor, I'll need to see the signed testimony of
two reputable adult witnesses, who have no connection to any business
that profits in any way from the production, sale, or consumption of food,
and who will swear in a public meeting, presided over by three respected
members of their community, that they personally saw more than one of
the alleged beakless double-breasted chickens in the same place at the
same time.

A photo is not acceptable ... not for me, and not for the two witnesses.

Evgesh-ka [11]

Answer:

Smaller by 7 times

Explanation:

Rotational mass is called moment of inertia

So, initial moment of inertia, I1 = I

initial angular velocity, ω1 = ω

Final moment of inertia, I2 = 7I

Final angular velocity, ω2 = ω/7
