An airplane is flying through the air at a speed of 150 mph at a heading of 60 degrees. if the wind is blowing at 20 mph from th

Crazy boy [7]

Answer:

Explanation:

Given

speed of plane 150 mph

heading $60^{\circ}$

wind is blowing at 20 mph from south-east

velocity of plane w.r.t. wind

$v_{pw}=150(\cos 60\hat{i}+\sin 60\hat{j})$

$v_{w}=20(\cos 45\hat{i}-\sin 45\hat{j})$

$v_{p}=v_{pw}+v_{w}$

$v_{p}=(150\cos 60+20\cos 45)\hat{i}+(150\sin 60-20\sin 45 )\hat{j}$

$v_{p}=89.14\hat{i}+115.76\hat{j}$

$|v_{p}|=146.103 m/s$

(b)after 30 minutes

Plane traveled in x direction $=89.14\times 0.5=44.57 miles$

Plane in Y direction $=115.76\times 0.5=57.88 miles$

Total distance $=\sqrt{x^2+y^2}=73.05 miles$

direction $tan\theta =\frac{115.76}{89.14}=1.298$

$\theta =52.38^{\circ}$ w.r.t east

3. Which types of light are not absorbed by genetic material?

Radda [10]

Given what we know, we can confirm that genetic material is not known to absorb light originating from an infrared or microwave radio source.

<h3>What light does genetic material absorb?</h3>

Genetic material is known to absorb UV light.
This represents ultraviolet light.
UV light is electromagnetic radiation, and the primary source of UV light that we are exposed to is the sun.

Therefore, given that the only form of light listed that genetic material is known to absorb is that of Ultraviolet or UV light, we can confirm that the answer to the question proposed is infrared and microwave radio light.

At room temperature, an oxygen molecule, with mass of 5.31x10-26kg , typically has a kinetic energy of about 6.21x10-21J.How fas

<h2>Oxygen is moving at 483.63 m/s</h2>

Explanation:

Kinetic energy = 0.5 x Mass x Velocity²

Kinetic energy = 6.21 x 10⁻²¹ J

Mass = 5.31 x 10⁻²⁶ kg

Substituting

Kinetic energy = 0.5 x Mass x Velocity²

6.21 x 10⁻²¹ = 0.5 x 5.31 x 10⁻²⁶ x Velocity²

Velocity² = 2.34 x 10⁵

Velocity = 483.63 m/s

Oxygen is moving at 483.63 m/s
