Overcooking decreases the nutritive value of food. Roughage present in vegetables and fruits should not be discarded as it is good for our digestive system. Preserved food has preservatives in it and other conditions unsuitable for microbial growth. Growing children need more proteins to build strong muscles.

Subject :NSO    Class : Class 8

Read the given passage and answer the questions 46 and 47.
The force of friction not only tends to stop a moving object, it also tends to stop a stationary object from moving. That is why it is difficult to push a stone to get it to move on a rough surface.

Friction is almost independent of.
(i) velocity of moving body
(ii) Weight of moving body
(iii) Nature of contact surface of moving body
(iv) Shape of moving body

A(i) and (iv)
B(ii) and (iii)
C(ii) only
DNone of these


when velocity is 0 static friction comes into play and when the velocity increases kinetic fraction comes into action and thus the friction decreases

Ans 1:

BEENA THOMAS from BCRS, Thiruvalla
Class : Class 6
AND when shape of an object is spherical it undergoes rolling friction and when the shape is a flat surface the moving object undergoes sliding friction which is greater than rolling friction

Ans 2:

AKSHAJ SRIVASTAVA from MOUNT LITERA ZEE SCHOOL, Kanpur
Class : Class 9
But if the shape of the object is streamlined then then the force of friction exerted on it will be less

Ans 3:

Antarik Maity from Bharatiya Vidyabhaban, Kolkata
Class : Class 8
Friction depends on the shape of the body as well....the option is incorrect

Ans 4:

from DPS Gurgaon, Gurgaon
Class : Class 5
shape of the body affects the drag friction also sliding and rolling friction would be same if shape did not matter.

Ans 5:

Rudreshwar Gadhari from SSRVM, Mumbai
Class : Class 9
ya i agree with u both
