Answer:

Because it kills people. I have had 6 relatives who have died from it in the past 2 years. It's horrible.

Explanation:

If you're wondering what causes cancer, it is rapid and uncontrollable cell regeneration. The majority of cancers result from random mutations arising during DNA replication in the normal stem cells required during development and tissue maintenance.

An airplane flies at a speed of 250 mi/hr, 40 degrees south of east. A wind blows at a speed of 35 mi/hr 30 degrees west of sout

alina1380 [7]

Compute the components of the given vectors. Let $P$ denote the plane's velocity vector, and $W$ the wind. Then

$P=\langle P_x,P_y\rangle=\langle250\cos(-40^\circ),250\sin(-40^\circ)\rangle$

$\implies P=\langle191.5,-160.7\rangle$

$W=\langle35\cos(-120^\circ),35\sin(-120^\circ)\rangle=\langle-17.5,-30.3\rangle$

The resultant velocity (rounded) is

$P+W=\langle174,-191\rangle$

with magnitude $\sqrt{174^2+(-191)^2}=258$ and direction $\tan^{-1}\frac{-191}{174}=-47.7^\circ$ , or about 258 mi/hr at 47.7 degrees south of east.

The y component of a vector R of magnitude k = Bcm shown in the figure below is Ky = +6 cm. What is the direction of this vector

WARRIOR [948]

Given

The y-component of vector K is

$K_y=6\text{ cm}$

The magnitude of vector K is , K=8 cm

To find

The angle

$\theta$

Explanation

Resolving K along its y-component we have,

$\begin{gathered} K_y=Ksin\theta \\ \Rightarrow6=8sin\theta \\ \Rightarrow sin\theta=\frac{3}{4} \\ \Rightarrow\theta=48.59\text{ }^o \end{gathered}$

Conclusion

The angle made with the x-axis is

$48.59^o$

Mr. Barcena reached a top speed of 5m/s in 2 seconds from rest, what was his average acceleration including units?

sashaice [31]

Answer:

Explanation:

The equation for acceleration is

$a=\frac{v_f-v_0}{t}$ where vf is the final velocity and v0 is the initial velocity. Filling in:

$a=\frac{5-0}{2}$ so

a = 2.5 m/s/s
