Answer:</h2>
<h2>_____________________________________</h2><h3>ENDOTHERMIC REACTIONS:</h3>
Endothermic Reaction are those reactions in which the reactants absorb the energy from their surrounding and forms the product.
<h2>_____________________________________</h2><h3>How to know endothermic reaction?</h3>
Those changes in which a substance goes from More-ordered state to less-oredered state are endothermic. Where they change from less ordered to more ordered is exothermic.
More ordered means that the movement of vibration of the particles of the substance is less and the are more close to each other. More to less ordered state is given as,
Solid>Liquid>Gas.
<h2>_____________________________________</h2><h2>Question:</h2>
In the question it asks about the melting of the ice cube. Ice cube is a solid, and when it will melt, it will change into the liquid water. As we know that, Solid is more ordered and Liquid is less ordered, and The change from more-ordered to less-ordered is endothermic thus the answer is ENDOTHERMIC.

Base on the said question or problem that state and ask to calculate the current of the said light bulb and in my further calculation and further analysis, I would say that the current of the light bulb would be 0.0292. I hope you are satisfied with my answer and feel free to ask for more
Answer:
A positive charge experiences a force in the direction of an electric field.
Explanation:
Electric field is defined as the electric force acting per unit positive charge. Mathematically, it is given by :
We know that like charges repel each other while unlike charges attract each other. The direction of electric field is in the direction of electric force. For a positive charge the field lines are outwards and for a negative charge the electric field lines are inwards.
So, the correct option is (b) "A positive charge experiences a force in the direction of an electric field".
Chemical to kinetic +( heat + sound)
The energy formations in brackets are wasted and passed on to their surroundings.
Hope this helps! :)
