What is the difference between light and reflection ?

Reflection is when light bounces off an object, while refraction is when light bends while passing through an object. When you look at a mirror the light bounces of the mirror from different angles, so you can see your reflection.

A 20 g ball of clay traveling east at 4.5 m/s collides with a 45 g ball of clay traveling north at 2.0 m/s. You may want to revi

Answer:

The ball travels with a speed of 1.96 m/s in a North East direction

Explanation:

Based on the law of conservation of linear momentum, we have that

$m_{1}v_{1}+m_{2}v_{2}=(m_{1}+m_{2})v$

Since this problem involves motion in both the x and y coordinates, we will solve it in the separate coordinates, and then find the resultant as our answer.

Momentum in the x- direction

in the x direction, $v_{2}= 0$ . this makes $m_{2}v_{2}=0$

hence we have

$20\times4.5=65v_{x}$

$v_{x}=1.385m/s$

Momentum in the y- direction

in the y direction, $v_{1}= 0$ . this makes $m_{1}v_{1}=0$

hence we have

$45\times2.0=65v_{y}$

$v_{y}=1.385m/s$

The resultant of the two vectors can be found using Pythagoras' theorem

$v=\sqrt{1.385^{2}+1.385^{2}} =1.959$

The direction of the resultant vector is found as

$Tan^{-1}(\frac{1.385}{1.385})=45degrees$

Hence the ball moves with a velocity of 1.96m/s in a North East direction

Gibbons move through the trees by swinging from successive handholds, as we have seen. To increase their speed, gibbons may brin

Sedbober [7]

By bring their legs close to their bodies, they are decreasing the length of the pendulum which help them move more quickly.

A pendulum is nothing but a body suspended from a fixed point so that it can swing back and forth under the influence of gravity.

Here in this case Gibbons are bringing their legs close to their bodies and reducing the length of the pendulum. Since as the length of the pendulum increases the speed of the movement will be reduced. By bringing their legs close to their bodies they are reducing the length and in turn their speed increase and they move quickly.

a) For a given material, would you expect the surface energy to be greater than, the same as, or less than the grain boundary en

sergejj [24]

Answer / Explanation:

To properly answer this question, let us define what a grain boundary is:

A grain boundary is the interface between multiple grains or crystals in a poly-crystalline material. They could also be refereed to as defects in the crystal structure and tend to decrease the electrical and thermal conductivity of structures.

Now, if we refer back to the question asked,

(a) The surface energy is grater than the grain boundary energy because surface atom have fewer bonds than atom along a grain boundary.

Consequentially, the lower the number of bonds formed, the higher the energy

(b) A higher angle grain boundary has higher misalignment and hence greater disruption of bonds (lesser number of bonds) than a small angle grain boundary. Therefore, a high angle grain boundary has higher energy.
