Answer:
Same mass
Explanation:
5kg and 5kg are the same that's the explanation
<u>Answer</u>
80 coils
<u>Explanation</u>
The turn rule of a transformer says that, the amount of voltage induced in the secondary coil is proportional to the number of coil. It is simplified by the ratio:
N<em>p/</em><em>N</em><em>s = </em><em>V</em><em>p/</em><em>V</em><em>s</em>
200/Ns = 25,000/10,000
200 × 10,000 = 25,000Ns
2,000,000 = 25000Ns
Dividing both sides by 25,000,
Ns = 2,000,000/25,000
= 80 coils
Answer:
Explanation:
given,
refractive index of lens, n = 1.70
Radius of curvature of front surface. R₁ = 20 cm
Radius of curvature of the back surface, R₂ = 30 cm
focal length= ?
R₁ = +20 cm
R₂ = -30 cm
n = 1.70
the focal length of the lens is equal to 17.15 cm
The answer would be B.

Standard deviation basically measures how spread out the values are. Without solving, you can easily tell which one among your choices have a smaller deviation. The closer the values are to each other the smaller the standard deviation. The values of choice B are the closest together, so you can assume that they have the smallest standard deviation. </span>
If time is specified, the distance may be estimated in constant acceleration using the formula: X=(at2)/2 if the beginning velocity is 0. (A automobile begins from a stop...) As a result, X=(6*10*10)/2=600/2 = 300 m.
