Answer:
ORIGINAL MOMENTUM OF THE PENCIL GETS DISTRIBUTED TO THE BROKEN HALFS EQUALLY .
Explanation:
GENERALLY :
- For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.
- The above statement tells us that the total momentum of a collection of objects (a system) is conserved - that is, the total amount of momentum is a constant or unchanging value.
- Since the forces between the two objects are equal in magnitude and opposite in direction, and since the times for which these forces act are equal in magnitude, it follows that the impulses experienced by the two objects are also equal in magnitude and opposite in direction.
IN THIS CASE :
<em>(neglecting the impulse and force of gravity)</em>
- <em>The net external force on the system is ZERO</em>
- <em>The collision and the breakage that happens is PURELY due to the internal force which are equal and opposite.</em>
- <em>When we consider the wall and the pencil together as a system , the net external force on the system is zero. </em>
- <em>We also assume that the wall is very heavy and thus it remains at rest even after the collision. </em>
- <em>Thus , according to the law of conservation of momentum, the pencil must have the same momentum imparted to it initially.</em>
- Therefore , the ORIGINAL MOMENTUM OF THE PENCIL GETS DISTRIBUTED TO THE BROKEN HALFS EQUALLY .
Water in the atmosphere and within the clouds themselves cause light waves to refract and reflect, creating an assortment of colors. The patterns occur when light is absorbed by water droplets within the clouds. The amount of absorption that occurs depends on the temperature of the air. The patterns occur when light is reflected from water droplets within the clouds. The amount of reflection that occurs depends on the wavelength of the light, and shorter wavelengths are reflected at a greater angle than longer ones.
Hope this helps!!
False. Kepler discovered this and Newton was inspired by this.
The examples may be;
making yogurt; If you heat beyond 130F you kill the cultures. The higher the temperature up until that point the faster it cultures until you close in on killer temperature.
Mixing 2 part epoxy; Keep it cool and the reaction time is delayed. On the other hand, heat it up and epoxy reacts quicker. In the winter time and close to 35 Degrees, the reaction time for cement to harden can take 400% more time to set.
