Answer:
I = 0.058 [A]
Explanation:
Ohm's law is defined as voltage equal to the product of current by resistance.
where:
V = voltage = 4.2 [V]
I = current [amp]
R = resistivity = 72 [ohm]
Now clearing I, we have:
The blood then carries oxygeb around the body which this helps us to breath around the body this process happens again
<span>Water that flows downhill along the earth’s surface is
called runoff. Runoff or also called as surface water runoff or overland flows
is the flow of water when there’s excess water caused by ice melted, rain or
storm. These occur because maybe the rain or the storm pours so hard and quick
that the soil can’t absorb it fastly. If runoff water flows on the ground and
reached a channel, it is called as nonpoint source. One example of nonpoint
source are the canals full of leaves, the water can’t continue flowing because
the leaves stops it.

Answer:
1. Potential hazard
2. Mining opportunity
Explanation:
The two reason, why astronomers are so interested in the discovery of additional Earth-approaching asteroids:
1. Potential hazard: We have proof that the dinosaurs got extinct because of an asteroid/comet strike on Earth. Also we have seen the effects of the Tunguska event and Chelyabinsk tragedy. These are enough to show us that asteroids can be very dangerous and wipe out the life from Earth.
2. Mining Opportunity: We have discovered a lot of asteroids which contains a lot of metal and precious elements. There can be a possibility of mining such asteroids in the future and reducing the burden on Earth.
