Explanation:
- area of rectangle=l×b
2.area of rectangle=l×b
3. perimeter of square=4×L
4. perimeter of rectangle=2(L+b)
- 14=2(4+b)
- 14=8+2b
- 2b=6
- b=3cm
hope it helps.
Answer:
When for example, heating up an ice cube the particles of the ice start to vibrate fast enough to get separated into liquid caused from high temperature. So the answer is Higher.
Answer:Krypton is a noble gas and has a full valence electron shell, is chemically non-reactive, and located in group 8A
Explanation:krypton are element of group 18(VIIIA) and are refer to as noble gases because they often dont react with other gases. They are in active gases usually not found in large quantity like other elements such as Nitrogen,oxygen...It has six Isotopes/other forms and can be used for filling lamps.
The gravitational potential energy is a <u>type of potential energy that depends on the height and is associated with the gravitational force</u>. This type of energy will depend on the height of an object in relation to some point of reference (which is usually the ground), the mass and the force of gravity.
<u>The relationship between gravitational potential energy (Epg), weight and height is given by the following equation,
</u>
Epg = weight x height = mass x acceleration of gravity x height
From this formula it can be observed that by decreasing the height of an object in relation to a surface, the potential energy of the body decreases, since the gravitational potential energy is inversely proportional to the height. <u>This is the reason why the amount of potential energy decreased as the puck falls.</u>
