Answer:
Option d.
Explanation:
An endergonic response alludes to a chemical reaction where energy is being utilized in the general response, making the response non-unconstrained and thermodynamically not favorable for the reaction.
Energy is being assimilated as the reaction continues and there is an overall deficit of energy in the encompassing system.
Endergonic responses require a contribution of energy, normally greater than those of non unconstrained exergonic responses, from an outside source in order to disrupt the equilibrium to cause variations, for example, formation of bonds.
This contribution of energy is known as the activation energy. In specific responses, an impetus is accessible to accelerate endergonic responses.
The energy for an endergonic response or reaction is acquired by coupling the response with an exergonic response.
Answer:
J=0.211kg.m/s
Explanation:
The impulse-momentum theorem states:
The velocity before the impact is given by:
For the velocity after the impact:
so:

-90.0 °F = -67 and 7/9 °C
-90.0 °F also = +205.372 K
-5.0 °C = +23 °F
-5.0 °C also = +268.15 K
