I know A is correct though
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.
Answer:
kinetic energy is 1/2mv^2.
which is 1/2×0.05×3^2
1/2×0.05×9.
1/2×0.45=
0.45÷2=0.225~0.23J
Locomotion is the ability to move from place to place, or the act of doing so.
Answer:
If you’re going to be shooting a lot, get a surplus flak jacket. This isn’t a bulletproof vest, it just stops fragmentation or shrapnel. More importantly, it absorbs shock. You can fire a 12 gauge shotgun all day long and you won’t feel sore at all.
hope it helps
