Answer: Earthquakes and Volcanic eruptions
Explanation:
You did not attach a picture however, this should be the correct answer.
Mid-oceanic ridge plate boundaries such as the Mid-Atlantic Ridge form as a result of plate separating at the boundary. This leads to earthquakes due to the forces of tension acting on the plates.
When this happens, the mantle is exposed and therefore there will be volcanic eruptions as the lava comes to the surface as magma. When this magma cools it creates new seafloors and underwater mountains.
Answer:
the final potential energy of this system is 3U0/10
Explanation:
We are given
charge at left end and another test charge at point p
Potential energy is given by =
where k is electrostatics constant = ![9 *10^9](https://tex.z-dn.net/?f=9%20%2A10%5E9)
Q1 = first charge , Q2= test charge
R= distance between charges
potential at point p
U0 = k*Q1*Q2 /3 ⇒ kq1q2 = 3U0 ..............1
now the test charge moves to point R
using Pytahgoreou theorem
R(distance) =
= 10
New Potential energy
U1 = kq1*q2 / 10
substituting kq1q2 = 3U0 from 1
U1 = 3U0/10
So this is the final potential energy of this system.

Explanation:
It is given that,
The ramp is tilted upwards at 25 degrees and Paul is pulling a large crate up the ramp with a rope that angles 10° above the ramp.
Total angle with respect to ramp is 35 degrees.
If Paul pulls with a force of 550 N.
The horizontal component of the force is given by :
![F_x=F\ cos\theta](https://tex.z-dn.net/?f=F_x%3DF%5C%20cos%5Ctheta)
![F_x=550\ cos(35)](https://tex.z-dn.net/?f=F_x%3D550%5C%20cos%2835%29)
![F_x=450.53\ N](https://tex.z-dn.net/?f=F_x%3D450.53%5C%20N)
The vertical component of the force is given by :
![F_y=F\ sin\theta](https://tex.z-dn.net/?f=F_y%3DF%5C%20sin%5Ctheta)
![F_y=550\ sin(35)](https://tex.z-dn.net/?f=F_y%3D550%5C%20sin%2835%29)
![F_y=315.46\ N](https://tex.z-dn.net/?f=F_y%3D315.46%5C%20N)
Hence, this is the required solution.
