Answer:
Option C: "The rock will slow down and eventually stop"
Explanation:
Since this is a real event, and not an ideal situation where there is no friction forces acting between the frozen pond and the rock, there is going to exist some force of dynamic friction (even small) acting between them. One can look up coefficients of dynamic friction between similar objects, and realize that some small force will be acting as the rock slides on the surface of the pond. That force acts always opposite the direction of movement, therefore decelerating the rock. The rock's speed will continue reducing in magnitude until it eventually stops.
Then, the selected answer is: "The rock will slow down and eventually stop."
Its not really definable. Say, you can have a full moon on the last day of November, and have the waning phases throughout the first half. Or you can have a new moon on the last day of December, and have the waxing phases during the first half of the month.

Answer:
A. Zero
Explanation:
The force on a coil of N turns, enclosing an area, A and carrying a current I in the presence of a magnetic field B, is :
F = N * I * A * B * sinθ
Where θ is the angle between the normal of the enclosed area and the magnetic field.
Since the normal of the area is parallel to the magnetic field, θ = 0
Hence:
F = NIABsin0
F = 0 or Zero
They are incline hope this helps!
Class 1 lever
Explanation:
In a class 1 lever, the fulcrum is placed between the effort and the load. This lever systems is the most common.
- The effort is the force input and the load is the force output
- The fulcrum is a hinge between the load and effort.
- Movement of the effort and load are in opposite directions.
- There are other classes of lever like the class 2 and 3.
- They all have different load, fulcrum and effort configurations
