A box is dropped onto a conveyor belt moving at 3.2 m/s. If the coefficient of friction between the box and the belt is 0.28, ho
Lemur [1.5K]

Answer:

t = 1.16 s.

Explanation:

Given,

speed of conveyor belt, v = 3.2 m/s

coefficient of friction,f = 0.28

Using newton second law

f = ma

and we also know that frictional force

f = μ N

f = μ m g

equating both the force equation

a = μ g

a = 0.28 x 9.81

a = 2.75 m/s²

Using Kinematic equation

v = u + at

3.2 = 0 + 2.75 x t

t = 1.16 s.

Time taken by the box to move without slipping is 1.16 s.

What are some characteristics of soil? ​
Anarel [89]

Soils are composed of organic matter (stuff that used to be alive, like plants and animals) and small inorganic matter. There are three basic soil types: sand, silt, and clay. Sand is comprised of tiny rock fragments and is the roughest in texture. Clay becomes sticky or greasy when wet, and very hard when dry.

Do magnetic field lines ever start or end anywhere?
nevsk [136]

Answer:

No

Explanation:

The lines of the field of a magnet don't begin or stop at anyplace, they generally make shut circles or loops and will proceed inside magnet (however here and there they are not drawn along these lines). We require an approach to show the bearing of the field.  

The field lines of a magnet don't simply end at the magnetic tip. They go directly through it, so that inside the magnet the magnetic field lines indicates from the south to the north pole.
