The Sentences which should Include in Laasya Explanation are :
B. Decomposers breakdown Dead Organisms.
D. Decomposers help to recycle Nutrients in an Ecosystem.
<u>Because </u>:
✿ Plants are Producers, But not Decomposers
✿ Ecosystems cannot function without Decomposers.
✿ Decomposers do not include Producers
Answer:
The speed is constant.
Speed is a scalar quantity (magnitude only).
Velocity is a vector quantity (magnitude and direction).
For an object in Uniform Circular Motion the change in velocity is always
directed towards the center of the circle, and this change of velocity
gives rise to the acceleration which is directed towards the center of
rotation. This is called the centripetal acceleration, and it is the centripetal
force (for instance the attraction of the moon towards the earth) which
produces the centripetal acceleration.
Answer: S2P6
The electronic configuraiton of given elements are as follows:
Ne =<span><span><span>[<span>He</span><span>]2</span></span><span>s2 2</span><span>p6<span>
</span></span></span>Ar = </span><span><span><span>[<span>Ne</span><span>]3</span></span><span>s2 3</span><span>p6<span>
</span></span></span>Kr = </span><span><span>[<span>Ar</span><span>]4</span></span><span>s2 3</span><span>d10 4</span>p6</span>
As it can be seen that for all three elements, their outermost orbital are completely filled, that is it has both s orbital, p orbital and d orbital fulfilled. Noble or inert gas atoms like Neon, Argon, Krypton have fulfilled valence shell. Fulfilled outermost orbital is the most stable electronic state, hence all elements tends to achieve such stability. These noble gas elements are called inert gas because of their fulfilled outermost shell. This means they don't react easily or take part in eletron donating, receiving or sharing. This is because, for all other elements except inert gas atoms, their valence shell is incomplete and they tend to react by other atoms so as to complete their outermost shell , which we call as duplet (in case of Helium like) or Octet state. Such elements either donate some electrons or receive some to acheive such stable state..
Answer:
45 j
Explanation:
At the top, the KE will have been converted to PE
KE = 1/2 mv^2 =PEat-top = 1/2 10 *3^9 = 45 j
D is the answer! Hope it helps
