Answer:
Exchange Reaction
Explanation:
The given reaction AB + CD = AD + CB is known as exchange reaction
At the beginning of the process, AB and CD must pass through decomposition reaction by breaking up. After that, A and D must form by synthetic reaction and likewise C and B
The chemical reaction involves exchange of chemical elements between the chemical components AB and CD.
Therefore, The type of example represented by the reaction
AB + CD = AD + CB
is known as Exchange reaction.
Earth quake cause the plates move to Cause either a big or small reaction called an earth quake
Answer:
10.2 m .
Explanation:
Let object falls by angle θ .
At any moment after the fall , there are two forces acting on the sphere
1 ) mg cosθ which is a component of weight towards the centre 2 ) normal reaction of the surface R .
mgcosθ - R is net force acting, which provides centripetal force
mgcosθ - R = mv² / r
But v² = 2g r( 1-cosθ ) [ object falls by height ( r - r cosθ ).
mgcosθ - R = m / r x 2g r( 1-cosθ )
When the object is no longer in touch with sphere,
R = 0
mgcosθ = m / r x 2g r( 1-cosθ )
3 gr cosθ = 2gr
cosθ = 2/3
height of fall
= r ( 1-cosθ )
r ( 1 - 2/3 )
1/3 r
1/3 x 15.3
5.1 m
Height from the ground
15.3 - 5.1
10.2 m .
