Answer:

The formation of volcanic arcs, trenches and subsidence leads to the production of volcanic eruptions.

Explanation:

  • North America plate makes a convergent boundary along with the pacific oceans. The is man reason for the development of the volcanoes and the origin of the earthquakes. The collusion of both these pales leads to the formation of a volcanic ring of fire that can be seen in the pacific ocean.

Answer:

The answer is (d) is totally reflected

Explanation:

Using the total internal reflection concept.

This concept state that:

"If the angle of incidence is greater than the critical angle then the light will not refract but it will reflect back totally"

Using the above statement, as incident angle is 42 degree and critical angle is 41 degree it means incident angle is greater than the critical angle. Therefore, light will not refract but it will totally reflected.

A boy reaches out of a window and tosses a ball straight up with a speed of 10 m/s. The ball is 20 m above the ground as he rele
HACTEHA [7]

Answer:

25 m

9.9 m/s

22 m/s

Explanation:

m = Mass of ball

v = Velocity

g = Acceleration due to gravity = 9.81 m/s²

Applying conservation of energy

mgh=\dfrac{1}{2}mv^2\\\Rightarrow h=\dfrac{v^2}{g}\\\Rightarrow h=\dfrac{10^2}{2\times 9.81}\\\Rightarrow h=5.09683\ m

The height above the ground is 5.09683+20 = 25.09683 m = 25 m

mgh=\dfrac{1}{2}mv^2\\\Rightarrow v=\sqrt{2gh}\\\Rightarrow v=\sqrt{2\times 9.81\times 5}\\\Rightarrow v=9.9\ m/s

The ball's speed as it passes the window on its way down is 9.9 m/s

mgh=\dfrac{1}{2}mv^2\\\Rightarrow v=\sqrt{2gh}\\\Rightarrow v=\sqrt{2\times 9.81\times 25}\\\Rightarrow v=22.14723\ m/s

The speed of impact on the ground is 22 m/s

marta [7]
Mmm tricky.
Since the velocity is constant, I'm going to assume there is no acceleration in any direction. This means there is no net force in the I or J forection!

Since there are 2 forces, both must be equal and opposite in direction to perfectly cancel each other out.

So the opposite of F1 is (-2N)I + (6N)J!
