Answer:
I'm not great at science, but I believe that the answer is elastic potential energy.
Explanation:
Components of mechanical systems store elastic potential energy if they are deformed when forces are applied to the system. Energy is transferred to an object by work when an external force displaces or deforms the object.
Answer:
D.Tetrahedral
Explanation:
The central atom has 0 lone pair and 4 bond pairs. Hybridization is sp³. The geometry is tetrahedral which has an angle of 109.5°.
According to VSEPR theory, each molecule arranges itself such that it faces minimum repulsion and the given molecule is of type 
.
Therefore the answer will be D.
D.Tetrahedral
Answer:
Explanation:
1 ) Let the initial horizontal velocity of car be v .
For vertical displacement
vertical displacement h = 21.3 - 2.3 = 19 m
Time taken to fall by 19 m be t
19 = 1/2 x 9.8 t² ( initial downward velocity is zero )
t = 1.97 s
This is also the time taken to cover horizontal displacement of 54 m which is width of river .
horizontal speed v = 54 / 1.97 m /s
v = 27.41 m /s
2 )
At the time of landing on other side , car will have both vertical and horizontal speed .
vertical speed
v = u + gt
= 0 + 9.8 x 1.97 = 19.31 m /s
horizontal speed will remain same as the initial speed = 27.41 m /s
Resultant speed = √ ( 27.41² + 19.31² )
= √ ( 751.3 + 372.87)
= 33.52 m /s
Answer:
<h3>This tends not to happen, because atoms are composed of charged particles that interact at a distance. ... Since the electrons are around the outside of the atom, those are the things that first interact, and as they have the same charge, they repel one another.</h3>
A. The electrons from atom repel each other
