A pilot heads his jet due east. The jet has a speed of 475 mi/h relative to the air. The wind is blowing due north with a speed

of 30 mi/h. (Assume that the i vector points east, and the j vector points north.)
a. Express the velocity of the wind as a vector in component form.
b. Express the velocity of the jet relative to the air as a vector in component form.
c. Find the true velocity of the jet as a vector.
d. Find the true speed of the jet. (Round your answer to the nearest integer.)
e. Find the direction of the jet.

Answer:

a) V = 30j

b) U = 475i

c) W = 475i + 30j

d) true speed = 475.95mi/h

e) Direction = 3.62°

Explanation:

The speed of the jet is 475mi/h relative to air.

The wind speed is 30mi/h to the north.

a) The velocity of the wind represented by a ve tor v in component form is given by:

V = 30j

b) The velocity of the jet relative to the air represented by a vector U in component form is given by:

U = 475i

c) The true velocity of the jet as a vector W is represented as W is given by:

W = U + V = 475i + 30j

d) The true speed of the jet is given by:

W = Sqrt(475^2 +30^2)

W = Sqrt(225625 + 900)

W = Sqrt(226525)

W = 475.95mi/h

e) The direction of the jet is given by :

Theta = Tan^-1 (30/475)

Theta = Tan^-1(0.06316)

Theta = 3.62°

A very long straight wire has charge per unit length 1.44×10-10C/m.
4vir4ik [10]

Answer:

Distance of the point where electric filed is 2.45 N/C is 1.06 m            

Explanation:

We have given charge per unit length, that is liner charge density \lambda =1.44\times 10^{-10}C/m

Electric field E = 2.45 N/C

We have to find the distance at which electric field is 2.45 N/C

We know that electric field due to linear charge is equal to

E=\frac{\lambda }{2\pi \epsilon _0r}, here \lambda is linear charge density and r is distance of the point where we have to find the electric field

So 2.45=\frac{1.44\times 10^{-10} }{2\times 3.14\times 8.85\times 10^{-12}\times r}

r = 1.06 m

So distance of the point where electric filed is 2.45 N/C is 1.06 m

Why is temperature a good criterion for searching for Earthlike exoplanets?
grandymaker [24]
Because it gives us the abilitity to find planets that have decent temperatures relative to earths temp so we can determine if the planet even has a possiblilty to sustain life hope this helps

N what direction does the medium move relative to the direction of the wave? Explain.
Mashcka [7]
Two types of mechanical waves: longitudinal<span> waves and </span>transverse<span> waves; the medium movement differs between the two.

</span>In a longitudinal wave the medium particle movement is parallel to the direction of wave propagation; example is sound wave in air.

I<span>n a transverse wave the medium particle movement is perpendicular to the direction of wave propagation; example is mechanical wave on a string.
