Answer:
a)The direction the frictional force will acts is in the positive x direction.
Explanation:
a)The direction the frictional force will acts is in the positive x direction
b)in the horizontal direction, the total force F(total) is equal to 4times the frictional force in the wheel.
F(total)=4f
''f'' is taken as the frictional force.
c)4times the normal force on each wheel minus the acceleration equals zero i.e 4N(wheel)-a=0
=4N(wheel)-mg=0
d) torque is the force that tends to bend rotation
ζ=rf
but acceleration=4×frictional force
cross multiply
f=ζ/r
f=ma/4
ma/4=ζ/r
a=4ζ/r
Answer:
There is no friction between the card and the cup.
Explanation:
Answer:
c) those caused by parasites
(A) The oxygen atom becomes strongly negative.
Explanation:
When a very electronegative atom like oxygen bonds to an atom with a lower electronegativity, like lithium, the oxygen atom becomes strongly negative and the lithium becomes strongly positive.
The attraction between these oppositely charged ions results in the formation ionic bond.
- An ionic bond is an interatomic bond in which a highly electronegative atom is bonded to less electronegative one.
- The electronegative nature of the oxgyen allows is to gain the electrons lost by weakly electronegative lthium.
- Most metals have low electronegativity.
- They then both will form ions.
- The attraction between the oppositely charged ions results in an ionic/electrovalent bonding.
