Starting from rest, an object rolls down along an inclined that rises by 3 in every 5(along it) . The object gains a speed of `sqrt10 frac(m)(s)` as it travel a distance of` frac(5)(3)m` along the incline. What can be the possible `shape//s` of the object?

Starting from rest, an object rolls down along an incline that rises by 3 in every 5 (along it). The object gains a speed of sqrt(10) m/s m/s as it travels a distance of 5/3 m along the incline. What can be the possible shape/s of the object ?

A rogid object is rolling down an inclined plane. Derive an expressions for the acceleration along the track and the speed after falling through a certain vertical distance.

An object takes 5 s to reach the ground from a height of 5 m on a planet. What is the value of g on the planet ?

An object takes 5s to reach the ground froma height of 5m on a planet.What is the value of g on the planet?

An object of mass 50 g moves uniformly along a circular orbit with an angular speed of 5 rad/s. If the linear speed of the particle is 25 m/s, what is the radius of the circle? Calculate the centripetal force acting on the particle.

An object of mass 5kg falls from rest through a verticle distance of 20m and reaches a velocity of 10ms^-1 . How much work is done by the push of the air on the object? (g = 10 ms^2)

An object of mass 100 gm moves uniformly along a circular orbit with an angular speed of 25rad//sec . If the linearspeed of particle is 25m//s then the radius of circle is

Read the following paragraph and answer the following questions given below it : Construction of a compound microscope : (i) Acompound microscope consists of a metal tube fitted with two convex lenses at the two ends. These lenses are called the objective lens ( the lens directed towards the object ) and the eyepiece ( the lens directed towards the eye ). Both the lenses are small in size , but the cross section of the objective lens has a short focal length . the focal length of the eyepiece is more than that of the objective lens . (ii) The metal tube is mounted on a stand . thr principal axes of the objective lens and the eyepiece are along the same line . The distance between the object and objective lens can be changed with a screw . It is possible to change the distance between the objective lens and the eyepiece. Working : (i) The object to be observed is illuminated and placed in front of the objective lens. slightly beyond the focal length of the objective lens. it's real , inverted and enlarged image is formed by the objective lens on the other side. (ii) This intermediate image lies with in the focal length of the eyepiece. It serves as an object for the eyepiece. The eyepiece works as a simple microscope . the final image is virtual, highly enlarged and inverted with respect to the original object . It can be formed at the minimum distance of distinct vision from the eyepiece . The final image is observed by keeping the eye close to the eyepiece. Use: This microscope is used to observe blood cells , microorganisms , etc. State which distance is adjusted to observe the object with a compound microscope ?
