For finding refractive index of a glass block, we use n=real-depth / apparent-depth For calculating apparent depth microscope is raised vertically until a clear focus is obtained of the underlying mark beneath the glass blob. Given that microscope is perpendicular to the mark, Wouldn't the...

Isn't it maximum kinetic fraction So It will oppose the opposite force by matching its value like in static friction OR is it different for kinetic friction?

I think the object will start to move with an acceleration and after that the kinetic frictional force will balance the applied force and object will have 0 acceleration and no change in previous motion and will continue to move with constant velocity.

Thank You guys I understand now. I think the reason I chose Answer 5 was because I got confused with the direction of motion and I also forget that Gravitational acceleration will be same no matter what the direction of motion is.

Static Friction applies in a non-moving body so distance applied is 0 The moment kinetic fraction takes over, object's velocity will be 0 and acceleration will be a non zero integer SO the kinetic energy will be 0 . After that moment velocity will increase linearly so kinetic energy will...

Net force in a particular direction should be higher than maximum static friction between the surfaces for motion to take place in that particular direction. I am more confused than before. From Live Science

No, we only need to overcome static friction but my question is whether it is possible? If not are there any theorems or proof that states it is impossible to achieve?

Are there any instances where kinetic coefficient of friction greater than static coefficient of friction? Is this possible in nature?

Have a look at this link Please explain me the answer I am so confused :(

The acceleration towards the Earth ip positive so when we throw the ball in opposite direction acceleration will be negative and this causes the initial velocity to decrease and become zero at some height after the U-turn object travels towards Earth which causes positive acceleration hence the...

I chose Answer 5 but the given answer was 1. Am I correct or what was the mistake?

Logically, Won't the center of gravity(Geometrical center) stay still and the ends would rotate (Like in a fan). If this the case, shouldn't the answer be 0 velocity because of it being in the center? (Zero motion at the center of fan)

I think the answer is ##\frac{mV}{M}## but I am not sure. Won't the cylinder tries to rotate due to the collision at one end? Is this anything related to Angular Momentum? The Answers given were,

I was able to derive, ##1/2*1*v_1^2 = 1/2*4*v_2^2 \\ v_1=2v_2 ## But I am confused whether the ratio is 1:2(Looking at the coefficient) or 2:1

Is there any abbreviation to 1D or 1E?
