Answer: Copper and oxygen
Explanation:
Copper and oxygen shares the ionic bond. As we know that ionic bond is the most strongest bond. Here is the order:
Hydrogen bond< Metallic bond< Ionic bond.
That means order in terms of increasing bond strength is :
Hydrogen and hydrogen< Copper and copper< Copper and oxygen.

to the moon=solar eclipse
The moon is on the side of

Answer:
The correct option is C
Explanation:
According to third equation of motion, v
2
=u
2
+2ax
Here, u=0 m/s
a=−g and x=−h
Negative sign indicates downward direction. Displacement and acceleration both are downwards.
So,v=±
2(−g)(−h)
We take minus sign because it is downwards.
v=−
2gh
After bouncing. velocity becomes 80% of v, i.e.,
v
′
=+0.8
2gh
(positive sign because the direction of ball has reversed after bouncing and is upwards.
Applying third equation of motion again, for u=v
′
, v=0 and a=−g
v
2
=u
2
+2×a×x
Thus,
0=0.64(2gh)+2(−g)x
or
x=0.64h
The turn signal indicator should be activated at least FIVE SECONDS before merging. This is done in order to let the other drivers behind you know that you want to turn and to slow down for you, this keeps you and other road users safe and prevent accident.
