An airplane in level flight travels horizontally with a constant eastward acceleration of 8.50 m/s2 and a constant northward acc

zloy xaker [14]

Answer:

$d = 3574.3 m$

Explanation:

Given that acceleration of the airplane is

$a_x = 8.50 m/s^2$

$a_y = -28 m/s^2$

initial velocity is given as

$v_x = 83.5 m/s$

$v_y = -15.5 m/s$

now we have displacement in x direction given as

$x = v_x t + \frac{1}{2}a_x t^2$

$x = (83.5)(14) + \frac{1}{2}(8.5)(14)^2$

$x = 2002 m$

Displacement along y direction is given as

$y = v_y t + \frac{1}{2}a_y t^2$

$y = (-15.5)(14) + \frac{1}{2}(-28)(14^2)$

$y = -2961 m$

so the magnitude of the displacement is given as

$d = \sqrt{x^2 + y^2}$

$d = \sqrt{2002^2 + 2961^2}$

$d = 3574.3 m$

Consider the uniform electric field \vec{E} =(4000~\hat{j}+3000~\hat{k})~\text{N/C} E ⃗ =(4000 j ^ +3000 k ^ ) N/

Answer:

Electric flux $\phi=31562.63\ Nm^2/C$

Explanation:

Given that,

Electric field acting on the circular area, $E=(4000j+3000k)\ N/C$

We need to find the electric flux through a circular area of radius 1.83 m that lies in the xy-plane. It lies in xy plane, such that the area vector point in z direction. The electric flux is given by :

$\phi=E{\cdot}A$

$\phi=(4000j+3000k){\cdot}Ak$

Using dot product properties, we get the value of electric flux as :

$\phi=3000\times Ak$

$\phi=3000\times \pi (1.83)^2$

$\phi=31562.63\ Nm^2/C$

So, the electric flux through a circular area is $\phi=31562.63\ Nm^2/C$ . Hence, this is the required solution.

What is an Environmental Footprint?

Mariana [72]

Answer: The measurement of human demand on nature is known as Environmental footprint.

Explanation:

The environmental footprint describes the effect of human activities on nature, the demand and supply.

For example, the consumption of natural resources and its replenishment is measured. The measurement of human demand on nature is known as Environmental footprint.

Far from any other masses, two masses, m1 and m2, are interacting gravitationally. The value for the mass of m1 suddenly doubles

NNADVOKAT [17]

<span>It also doubles The gravitational force between two masses is expressed as: F = G*m1*m2/r^2 where F = Force between the two masses m1 = Mass of object 1 m2 = Mass of object 2 r = distance between centers of object 1 and object 2 G = Gravitational constant The exact values of G, m1, m2, and r don't matter since all except for m1 is held constant. And when m1 suddenly doubles, the force attracting the two object to each other also doubles.</span>

Which is the best reason a writer would use a unreliable narrator

avanturin [10]

Answer: Explanation:

Authors sometimes use an Unreliable Narrator to tell the story, a protagonist who can't be trusted to tell the events accurately. Either they are insane, evil, delusional, forgetful, or just plain wrong... whatever their reasons, the writer uses this technique to 'hook' the reader.
