Answer: $67^{\circ}$

Explanation:

Given

Ray of light incident on plane making an angle of $23^{\circ}$ with normal

Thus incident angle $i=23^{\circ}$

So according to the law of incidence is equal to angle of reflection

$\angle i=\angle r$

thus $\angle r=23^{\circ}$

and angle between mirror and reflected ray $=90^{\circ}-23^{\circ}$

$=67^{\circ}$

olchik [2.2K]

Answer:

35°C

Explanation:

q = mCΔT

2130 J = (0.200 kg) (710 J/kg/°C) (T − 20.0°C)

T = 35°C

Process in which permanent deformation of metals occurs due to applied stress and results in breaking of bonds and then reformin

luda_lava [24]

Answer:

This process involves the motion of dislocations and is termed slip (or glide in some textbooks)

Explanation:

Plastic deformation of metals (and other crystalline materials) usually occurs by slip, which is the sliding of planes of atoms over one another by dislocation movements.

On a microscopic scale, stress causes planes of crystalline objects to leave their original position and slide over other planes into new positions, these microscopic movements manifest as a slip on a macroscopic scale. And the planes do not return back to their original position after the removal of the dislocation-causing stress.

A rock is thrown straight up with an initial velocity of 19.6 m/s. What time interval elapses between the rock’s being thrown an

inna [77]

Answer:

It will take 4 sec rock to comes its original point

Explanation:

It is given that the rock comes to its original point

So displacement S = 0 m

Initial velocity u = 19.6 m/sec

Acceleration due to gravity $g=9.8m/sec^2$
