Lots of reasons. one reason i lie alot (a very bad habit) is im scared of what will happen if i tell the truth. the truth is always better, though.
Answer:
Electric potential = 0.00054 V
Explanation:
We are given;
Charge; q = 3 pC = 3 × 10^(-12) C
Radius; r = 2 cm = 0.02 m
Formula for the electric potential of this surface will be;
V = kqr
Where;
K is a constant = 9 × 10^(9) N⋅m²/C².
Thus;
V = 9 × 10^(9) × 3 × 10^(-12) × 0.02
V = 0.00054 V
The answer & explanation for this question is given in the attachment below.
Answer:
B. 47-54 miles/hour
Explanation:
Gale is a strong wind which is depicted by red warning flag. According to U.S. National Weather Service gale is a sustained surface wind. It is also used to refer winds from tropical coastal areas.
On the basis of force of wind gale is divided in four groups:
- Near gale - 32-38 mph
- Gale - 39-46 mph
- Strong gale - 47-54 mph
- Storm - 55-63 mph
For this case, what we must do is to rewrite these measurements in the same unit in order to compare them.
By writing the measurements in meters we have:
![30 mm = (30) * (\frac{1}{1000}) = 0.030 m](https://tex.z-dn.net/?f=%2030%20mm%20%3D%20%2830%29%20%2A%20%28%5Cfrac%7B1%7D%7B1000%7D%29%20%3D%200.030%20m%20%20%20)
![30 cm = (30) * (\frac{1}{100}) = 0.30 m](https://tex.z-dn.net/?f=%2030%20cm%20%3D%20%2830%29%20%2A%20%28%5Cfrac%7B1%7D%7B100%7D%29%20%3D%200.30%20m%20%20%20)
![30 dm = (30) * (\frac{1}{10}) = 3 m\\30 Hm = (30) * (100) = 3000 m](https://tex.z-dn.net/?f=%2030%20dm%20%3D%20%2830%29%20%2A%20%28%5Cfrac%7B1%7D%7B10%7D%29%20%3D%203%20m%5C%5C30%20Hm%20%3D%20%2830%29%20%2A%20%28100%29%20%3D%203000%20m%20%20%20)
Therefore, physically the correct measure is:
![0.30 m = 30 cm](https://tex.z-dn.net/?f=%200.30%20m%20%3D%2030%20cm%20%20)
Answer:
the length of a student's textbook most likely is:
30 centimeters
