A plane is flying to Minnesota with a velocity of 277.73 km/h, N. The plane

Physics
1 answer:
umka2103 [35]1 year ago

Answer:

466 km/h

255°

measured anticlockwise from the east direction

Explanation:

find the resultant velocity of a plane after a crosswind affects its motion. take the positive

x -direction as east, and the positive y -direction as north. The components of the plane's velocity (without wind) are

  • <em>upx =</em> 0
  • <em>upy =  450 Km/ h</em>

<em>And for the wind.</em>

  • <em>uwx = - 120 Km/h</em>
  • <em>uwy = 0</em>

<em>The components for the r</em><em>esultant velocity </em><em>of the plane are given by</em>

  • <em>ux =upx + uwx = 0 - 120 Km/h =  </em><u><em>- 120 Km/h</em></u>
  • <em>uy = upy + uwy  = - 450 Km/h +0 = </em><u><em>- 450 Km/h</em></u>

<em>The </em><em>magnitude </em><em>of the resultant velocity is</em>

<em />\sqrt{(vx)^2+(vy)^2} =\sqrt{(-120lkm/h^2+(-450lkm/h)^2}

= 466 km/h

Hope this helps u : )

A conducting rod (length = 2.0 m) spins at a constant rate of 2.0 revolutions per second about an axis that is perpendicular to
vladimir2022 [97]

Answer:

0.050V

Explanation:

To solve this problem it is necessary to use the concepts related to the potential between two objects that have a magnetic field, this concept is represented in the equation.

\int dV = \int_{0}^{l/2} Bv (dl)

Where,

v= tangencial velocity

B = Magnetic Field

We know for definition that,

v= l\omega

Where,

L = length

\omega = Angular velocity

We can replace this values in our first equation then,

\int dV = \int_{0}^{l/2} B (l\omega) (dl)

Integrating we have,

V = \frac{1}{8} Bl^2 \omega

Replacing the values,

V= \frac{1}{8} (8*10^{-3})(12.56)(4)

V = 0.050V

Therefore the potential difference between the  center of the rod and the other rod is 0.050V

One horsepower (1 hp) is the unit of power based on the work that a horse can do in one second. This is defined, in English unit
nikdorinn [45]

Power is defined as rate of work done which means it is work done in 1 second of time

Now it is given that we have a horse that will give power 745.7 W

So it will do work of 745.7 J in  1 second of time

now if we wish to find the work done by horse in 0.55 s

so we can say

W = Power \times time

W = 745.7 \times 0.55

W = 410.14 J

So it will do total work of 410.14 J in 0.55 s of time

You perform the Hooke's Law experiment and create a plot of Displacement vs. Force. You add a linear fit and find the following
balandron [24]

Answer: 0.192 N/m

Explanation:

Well, generally when a Hooke's Law experiment is performed the plot is in fact Force vs Displacement, being the Force (in units of Newtons) in the Y-axis and the Displacement (in units of meters) in the X-axis.

In addition, if we add a linear fit the resultant equation will be the Line equation of the form:

Y=mX+b

Where m=\frac{Y_{2}-Y_{1}}{X_{2}-X_{1}} is the slope and b is the point where the line intersects the Y-axis.

So, if the equation is:

Y=0.192X+0.011

The slope of this line is 0.192 N/m which is also the spring constant k.

In cloud formation, water vapor turns into water droplets which get bigger and bigger until it rains.
Andreas93 [3]

Basically there will be an increase in the air temperature in the clouds. Internally the water vapor is condensed in a cloud to fall like rain and release all the heat that it has inside. This heat is physically known as 'latent heat'. With this release of energy released as water vapor becomes drops of water, a microphysical process will be generated in the clouds that are responsible for controlling the conversion of water vapor into cloud particles and their respective rainfall.

The correct answer is A: Get Warmer.
