Answer:
During the first quarter or last quarter phase of the moon, when the sun and moon are perpendicular (at right angles) to each other in relation to the Earth, the tidal gravitational pulls interfere with each other, producing weaker tides, known as neap tides.
Explanation:
Sports drinks do offer some benefits when comparing sports drinks vs. water. While water actually works better at fluid replacement, sports drinks are often more appealing to the palate. In other words, people who enjoy the taste of sports drinks may drink more of a sports drink than they would water; this will lead to better hydration.
Sports drinks also contain electrolytes and carbohydrates. While exercising for short periods of time, it is not necessary to replace electrolytes; however, athletes and marathon participants exercising for period of an hour or more can benefit from electrolyte replacement in particular. Carbohydrates offer the body energy. When the body burns calories, it needs carbohydrates to replace energy lost. The longer the workout, the more carbohydrates are needed.
I do not know what the school expects as an answer, but advantage of reflecting telescopes is that there is only one major reflecting surface, so it is quite easy to create a 6 or 8 inch telescope by an amateur, after adding on a prism and an eyepiece. (a microscope eyepiece could be used).
MY answer would be "easier to build". (it still takes tens of hours to grind and polish the single plane surface to a parabolic surface).
Electromagnetic waves all have the same velocity in the same medium. However, since frequencies vary widely, so do wavelengths.
Explanation:
Force (F) = 500 N
Distance (d) = 16 m
work done (w) =?
We know that
w = F * d
= 500 * 16
= 8000 Joule.
The bulldozer performs 8000 Joule.
Hope it will help you :)❤
Work is equal to a force over a distance and is equal to the change in kinetic energy, so

- Fd=ΔKE

<span>−Fd=1/2m<span>v22</span>−1/2m<span>v21</span></span>
<span>d=(1/2m<span>v22</span>−1/2m<span>v21</span>)/−F

We know that Ffric=kFnatural and Fnatural=mg so:
<span>d=(1/2m<span>v22</span>−1/2m<span>v21</span>)/−(k∗mg)</span><span>d=(−1/2<span>v21</span>)/−(k∗g)
</span><span>d=(−1/2×(14.6m/s<span>)2</span>)/−(0.137×9.8m/s)

d = 78.9m</span>
