Answer: the force increases as the angle increases
Explanation:
If we assume the incline plane is frictionless, the only force acting on an object on the incline plane is the force of gravity:
where m is the mass and g the acceleration due to gravity.
However, the actual force that makes the object sliding down along the incline is not the gravity itself, but the component of the force of gravity parallel to the surface of the incline, which is given by
where 
is the angle of the incline.
Therefore, we see that as the angle of the incline increases, the force on the object increases.
Answer:
Instantaneous speed means speed at any instant
that means Speed is changing with time
You know speed is distance/time
So that means distance is also changing with time
So we take infinitesimal small distance per infinitesimal small time As we assume speed is constant in infinitesimal small time dt
So, we take speed = ds/dt
ds = infinitesimal small distance
dt = infinitesimal small time
As its ratio is equal to speed at any instant
Note : We are taking infinitesimal small distance
But :) we are taking infinitesimal small time also
As you know if denominator is small fraction is large So fraction always give large value
So it's not O ( this makes confuse to most of students)
So, thanks
Good question
Keep thinking like this :)
Air resistance opposes the motion of falling objects. Dense air prefers to stay at low heights. More dense the air is, more air resistance it produces. Hence acceleration of falling objects decreases. Hope this helps!
The answer is pretty simple, the others don’t make sense really B. Law
The answer for this question would be choice
B) FALSE because pitch is the quality of sound. *I take no credit for the image below I just found it off google.
