Murrr4er [49]
The three types of stress that act on Earth's rocks are compression, tension and shear. Among all the options that are given in the question, the correct option is option "D". These kind of stress action creates the rocks to break in a natural way. The earth's rocks sometimes collide with one another, pull apart from each other and sometimes slide against each other. Whenever two rocks collide with each other, they create a compression force. When the two rocks of the earth tries to pull away from each other, it creates a tension force. The sliding of two earth's rocks creates a shearing force.

the magnitude of the electrical force acting between a +2.4x10-8c charge and 1+1.8x10-6 charge that are separated by 1.008m is
Temka [501]

Answer:

3.83×10¯⁴ N

Explanation:

From the question given above, the following data were obtained:

Charge 1 (q₁) = +2.4x10¯⁸ C

Charge 2 (q₂) = +1.8x10¯⁶ C

Distance apart (r) = 1.008 m

Electrical constant (K) = 9×10⁹ Nm²/C²

Force (F) =?

The magnitude of the electrical force acting between the two charges can be obtained as follow:

F = Kq₁q₂ / r²

F = 9×10⁹ × 2.4x10¯⁸ × 1.8x10¯⁶ / (1.008)²

F = 0.0003888 / 1.016064

F = 3.83×10¯⁴ N

Thus the magnitude of the electrical force acting between the two charges is 3.83×10¯⁴ N

A dog walks 12 meters to the east and then 16 meters back to the west for this motion what is the distance moved What is the mag
FinnZ [79.3K]

The distance is 28 meters, and the displacement is -4.

For the distance it would be 12 + 16 = 28.

For the displacement it would be 12 - 16 = -4.

would really appreciate a brainliest! Hope this helped!
