Answer: Gravitational forces are action-at-a-distance forces
Explanation:
Gravitational forces are action-at-a-distance forces that act between two objects even when they are held some distance apart. For example If you watch a roller coaster car move along its course, then you are witnessing an action-at-a-distance.
PART a)
As we know that weight is product of mass and gravity
so here we have
Part B)
Normal force is counter balanced by weight of the crate
so here we have
N = W = 127.4 N
PART C)
As we know that
F = ma
now we have
m = 13 kg
F = 40 N
now we have
Part D)
Maximum static friction force is given as
here we know that
now we have
PART E)
Since applied force on the block is
F = 12 N
Now since applied force is less than maximum static friction force
So it will not slide
So here friction force will be same as applied force
Static friction = 12 N
PART f)
Kinetic friction force is given as
here we know that
now friction force is
now we have
Part g)
as we know that
F = ma

The correct answer is; Yes, you can be unconsciously eavesdropping.
Further Explanation:
When this occurs it is called the “The Cocktail Party Phenomenon.” Your mind can focus on one conversation that is being made and drown out all other speech and things going on around you. This makes your brain have auditory attention on one specific conversation.
The sensory hearing in the person listening to the conversation is subconsciously filtering the conversation into its own stream in the brain. This phenomenon can also detect certain words that are important to the person with a large amount of noise in the background.
This occurs in the left hemisphere of the brain in the superior temporal gyrus region.

Answer: B
Explanation:
1) Apply Ampere's Law to the loop
The loop has a circumference of 2pir.
The current enclosed is multiplied by N because there is N distinct loops.
Answer is B
