This type of listening response is called back-channel signal. This allows the speaker to know that the listener is attentive or willing to engage a conversation between them. It is shown through short utterances, facial expressions, head nods and others.

<span>Exothermic reaction is a chemical reaction that releases energy. This reaction releases heat energy or light .
In an endotermic reaction energy is used.
Enthaply is the heat energy change , delta H.
If the sum of the enthalpies of the reactans is greater than the products the reaction is exothermic. If the products side has a larger enthaply than the process is endothermic. So, if delta H is negative then the process is exothermic. If delta H is positive, than the process is endothermic.
Exothermic are: A+BC -> AB+C
A2+B2 -> 2AB
Endothermic are:AB+C -> AC+B
A2 + C2 -> 2AC
B2+C2 -> 2BC</span>
Solution :
The motion in the y direction.
The time taken by the toy rocket to hit the ground,
S = distance travelled = 30 m
u = 0 m/s
a = 
t= time in seconds
Therefore, 
t = 2.47 sec
Now motion in the x direction,
u = 12 m/sec
Upon integration 'v' with respect to 't'
Once again integrating with respect to t,
= 0.0176+29.64
= 29.65 m
Therefore, the toy rocket will hit the ground at 29.65 m from the building.
False
It is impossible to get infinite energy let alone to put it inside one battery
