The image shows copper wire coiled around an iron nail and connected to a battery to create an electromagnet. which will increase the strength of this electromagnet? a. adding another battery to the circuit b. using a larger switch c. using a larger nail d. using a battery with lower voltage

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
