Answer:
A massive object (like a galaxy cluster) bends the light from an object (like a quasar) that lies behind it.
Explanation:
A massive object, like a galaxy cluster, is able to deform the space-time shape as a consequence of its own gravity, so the light that it is coming from a source that is behind it in the line of sight will be bend or distorts in a way that will be magnified, making small arcs around the cluster with the image of the background object.
This technique is useful for astronomers since they make research of faraway objects (at hight redshift) that otherwise will difficult to detect with a telescope.
It wont work because there is resistance in the circuit so it wont work as well
Answer:

Explanation:
According to my research on Anthropological Research methods, I can say that based on the information provided within the question this type of research method is called Participant Observation. This type of methodology is usually used among Anthropologists, and is defined as a method where researchers choose to live in the lives of the group or species that they are studying.
