falling parachutist you bail out of the helicopter of example 3 and pull the ripcord of your parachute. now in eq. (3), so your

downward velocity satisfies the initial value problem in order to investigate your chances of survival, construct a slope field for this differential equation and sketch the appropriate solution curve. what will your limiting velocity be? will a strategically located haystack do any good? how long will it take you to reach 95% of your limiting velocity?

You bail out of a helicopter and immediately open your parachute, so your downward velocity satisfies the initial value problem.

<h3>What is velocity ?</h3>

Velocity is the rate of change in direction of an item in motion as seen from a specific point of view and as measured by a specific unit of time. In kinematics, the area of classical mechanics that studies how bodies move, velocity is a fundamental idea.

A physical vector quantity called velocity requires both magnitude and direction to be defined. Speed, a coherently derived unit whose quantity is measured in the SI (metric system) as metres per second, is the scalar absolute value (magnitude) of velocity. For instance, "5 meters per second" is a scalar while "5 meters per second east" is a vector.

Please answer the following question.
Dima020 [189]

The oceanic lithosphere is a layer on the Earth's crust that consists of rocks of the mantle.

<h3>What is the lithosphere?</h3>

The lithosphere can be defined as the outer rock layer present on the Earth's surface.

The oceanic lithosphere is composed of different rocks of the mantle such as, among others, gabbro and/or basalt.

The structure of the oceanic lithosphere is similar around the world because it is slender compared to the continental lithosphere and always determined by the supply of magma.

In conclusion, the oceanic lithosphere is a layer on the Earth's crust that consists of rocks of the mantle.

I need help understanding this concept . Would appreciate it so much. Thank you
Firlakuza [10]

Answer:

Explanation:

Both these questions are based on the Universal Law of Gravitation, which is given by :

F = Gm1m2 / r²

2) F = 6.67 x 10⁻¹¹ x 8 x 10³ x 1.5 x 10³ / 1.5 x 1.5

   F = 6.67 x 10⁻⁵ x 8 / 1.5

   F = 35.57 x 10⁻⁵ N

3) F = 6.67 x 10⁻¹¹ x 7.5 x 10⁵ x 9.2 x 10⁷ / 7.29 x 10⁴

   F = 6.67 x 10⁻³ x 7.5 x 9.2 / 7.29

   F = 63.13 x 10⁻³ N

Does magnets exert a force. explain​
Ratling [72]

Answer:

Magnets exert forces and torques on each other due to the rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material. Hope this helps you! :)
