Two airplanes leave an airport at the same time. The velocity of the first airplane is 730 m/h at a heading of 65.3 ◦ . The velo
yanalaym [24]

Answer:

Plane will 741.6959 m apart after 1.7 hour                    

Explanation:

We have given time = 1.7 hr

So if we draw the vectors of a 2d graph we see that the difference in angles is   = 102^{\circ}-65.3^{\circ}=36.7^{\circ}

Speed of first plane  = 730 m/h

So distance traveled by first plane = 730×1.7 = 1241 m

Speed of second plane = 590 m/hr

So distance traveled by second plane = 590×1.7 = 1003 m

We represent these distances as two sides of the triangle, and the distance between the planes as the side opposing the angle 58.6.

Using the law of cosine, r^2 representing the distance between the planes, we see that:

r^2=1241^2+1003^2-2\times 1003\times 1241cos(36.7)=550112.8295

r = 741.6959 m

An object is transported to three different planets in our solar system. Which of the following is true about that object?
Digiron [165]

<u>Answer;</u>

<em>D.  The object’s weight changes, but its mass stays the same.</em>

<u>Explanation;</u>

  • Mass is the amount of matter in a object, which is measured in kilograms. Mass of an object is measured using a beam balance. It is important to note that the mass of an object or a body remains constant, and does not vary from one place to another. For instance the mass of a person on the moon will be the same as when the person is on the earth surface.
  • Weight on the other hand is the measurement of gravitational pull of an object. weight is measured using a spring balance and measured in Newtons. Weight varies from one place to another depending on the gravitational pull of a given surface.

Compared to the thickness and density of the continental crust of South America, the oceanic crust of the Pacific floor is______
chubhunter [2.5K]

Answer:

The pacific floor (oceanic crust) is thinner and more denser

Explanation:

The continental crust have a thickness of about 35 to 40 km on an average, and are composed of rocks that has less denser granitic minerals such as feldspar, quartz.

On the other hand, the oceanic crust have a thickness of about 7 to 10 km on an average, and it is comprised of denser mafic rocks that contains high amount of olivine and pyroxene minerals.

Due to this, the oceanic crust subducts below the continental crust during the time of collision.

Thus, the pacific floor (oceanic crust) is thinner and more denser, in comparison to the South American continental crust.
