Answer:
Maybe to get different readings
Answer:
≈ 22¢
Explanation:
240 / 1000 = 0.240 kV
0.240 kV(2.5 A)(3 hr) = 1.8 kW•hr
1.8 kW•hr($0.12/kW•hr) = $0.216
A solar eclipse occurs when the moon crosses in front of the Sun, blocking some or all of its rays. A lunar eclipse happens when the moon is directly behind the earth, blocking the moon from receiving light. The only light comes from the light on earth's reflected shadow.
You can look at a lunar eclipse because there is very little light or none at all. You can't look at a solar eclipse because you are looking directly at the sun unless it is complete. Before totality, only some of the Sun is blocked, causing your pupils dilate to let in more light. Since they do this, more of the Sun's rays can be let in to the eye, which effectively allows your eyes to burn.
Some doctors and eye care specialists say that after someone complains of blindness after looking at a solar eclipse unaided, they can see what the Sun and moon looked like at the time that they looked at it, as it is burned onto their retinas.
Answer:
0.2m/s2
Explanation:
acceleration= change in velocity ( in this case speed)/ change in time.
4.5-3.5=1m/s
change in time=5-0 =5
1m/s divided by 5 seconds acceleration as the result
<h3><u>Answer;</u></h3>
formed by erosion
River deltas <u>are formed by erosion</u>.
<h3><u>Explanation;</u></h3>
- <em><u>River delta refers to a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water.</u></em>
- In other words <em><u>river deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river</u></em>. It occurs when a River is entering a sea, an ocean, lake a reservoir or another river that is incapable of carrying the supplied sediment.
- Therefore,<u> deltas are formed as a result of erosion by water</u> which involves the carrying of sediments down the rivers to the mouth of river where it accumulates.
