Question: May one answer Amein to a brachah that he hears over the phone or over Zoom?

Short Answer: According to many contemporary poskim, we follow the ruling of Rav Moshe Feinstein zt”l and not the ruling of Rav Shlomo Zalman Auerbach zt”l, and allow one to recite Amein when hearing a live brachah recited over the phone, and by extension, over Zoom.

Question: With many minyanim giving the baal k’riah all the aliyos because of social distancing, should the baal k’riah recite “Chazak, chazak, v’nis’chazeik” after the completion of a sefer?

Short Answer: The baal k’riah should not recite “Chazak, chazak, v’nis’chazeik” in this situation, but there are some poskim who allow him to recite it.
