I believe
the answer is C. 0.14cm.
The zero error in vernier caliper is read by the distance by which the zero of the movable part of the scale is shifted from the zero of the cm ruler in the tool, which is the unmovable part of the tool. The movable part has a scale accuracy of 0.1 cm, while the other has a scale accuracy of 1 cm. And we always use the lowest scale, which is here the 0.1 scale which has greater accuracy with 10 times the 1 cm ruler, to find our errors.
Hope this helps!
Answer:
55N
Explanation:
Using Newton's second law of motion:
F=ma
Force=mass × acceleration
F=25×2.2
F=55N
So 55 Newtons are needed
Answer:
option (d)
Explanation:
The minimum angle of inclination of the inclined plane from the horizontal such that the object placed on the inclined plane is just start sliding down.
The value of angle of repose is given by the
tan θ = μ
Where, θ be the angle between the horizontal plane and the inclined plane and μ be the coefficient of friction.
It is also called as the angle of sliding.
