Explanation:The following data were obtained from the question:Mass (m) of box = 100 KgLength (L) of ramp = 4 mHeight (H) of ramp = 1.5 mMechanical advantage (MA) of ramp =? Mechanical advantage of a ramp is simply defined as the ratio of the length of the ramp to the height of the ramp. Mathematically, it is given by:Mechanical Advantage = Lenght / height MA= L/H With the above formula, we can obtain the mechanical advantage of the ramp as follow:Length (L) of ramp = 4 mHeight (H) of ramp = 1.5 mMechanical advantage (MA) of ramp =?MA = 4/1.5MA = 2.7Therefore, the mechanical advantage of the ramp is 2.7
In a computer simulation, Juan moves a magnet (Magnet 1) closer to another magnet (Magnet 2) that cannot move. Which statement accurately describes the change in potential energy?
a
The potential energy does not change because the magnets in the system do not change.
b
The potential energy increases because Magnet 1 moves against the magnetic force.
c
The potential energy decreases because Magnet 1 moves against the magnetic force.
d
The potential energy decreases because Magnet 1 moves in the same direction a
Answer:
C
Explanation:
The potential energy decreases because Magnet 1 moves against the magnetic force. If it was increased it would be kinetic
When Magnet 1 moves against the magnetic force, the potential energy will increase.
Potential energy:
It is the enregy of present in the object or system due to the position of the different parts of the system.
Here, when one magnet bring closer to another magnet the magnetic force will increase.
Therefore, when Magnet 1 moves against the magnetic force, the potential energy will increase.

I am not good at mysteries so please help!!
Answer:
The nephew
Explanation:
The dog's foot prints are overlapping the shoes that are overlapping the tire marks from 3 different tires, if the dog is his seeing dog then it would make sense that the dog's foot prints are next to his and they're going in the same direction, and since the dog's footprints overlap the others it means that they were there last.
People were confused so I'll resay it. The dog is the nephew's seeing dog, so he walks beside him. And if the dog's foot prints are overlapping all of the other's, that means the dog was there after all of the rest of them, and if the nephew is with the dog then the nephew was there last.
