-- If the field were inclined to the surface, then it would have
some component parallel to the surface.
-- Then, since we're talking about a conductor, the charges
on the object would move in response to that component
of the field, until there was no longer any component of the
field trying to move them.
Answer:
Static Friction-Friction that acts when the two objects are not moving
Sliding Friction-Two solid surfaces slide across each other
Rolling Friction-An object rolls across each other
Fluid Friction-Friction that occurs as an object moves through a fluid

Answer:
I think its B. Please keep in mind that I could be wrong.
Explanation:
Answer
given,
Stress for plastic deformation = 267 MPa
modulus of elasticity = 115 GPa
cross sectional area = 377 mm²
a) maximum load (in N) that may be applied to a specimen
= σ x A
= 267 x 10⁶ x 377 x 10⁻⁶
= 100659 N
b) modulus of elasticity = stress/strain
115 x 10⁹ =
L = 127 mm
115 x 10⁹ =

Δ l = 0.295 mm
maximum length after the stretched = 127 mm + 0.295 mm
= 127.295 mm
Answer:
W=f*d
= 50 * 15
=750 J
Therefore, the work done is 750 joule( J)
