Two point charges, the first with a charge of +3.50 10-8 C and the second with a charge of -4.50x10-6C, are separated by 25.0 cm

EastWind [94]

Answer:

Explanation:

Fe = (k)(Q1)(Q2) / d²

k ≈ 9 × 10⁹ N m² / C² [Coulomb's Constant] or 8.98 × 10⁹ (nearest hundredth).

q = particle charge [Coulombs; C]

d = distance [Meters; m]

Fe = Electrostatic force [Newtons; N]

________________________________

Fe = (9×10⁹)(3.5 × 10^(-8)(-4.5 × 10^(-6))/(.25)² N =

(9)(3.5)(-4.5) × (10^(9))(10^(-8))(10^(-6) / (.25)² N =

(9)(3.5)(-4.5) × (10^(9 - 8 - 6)) / (.25)² N =

(-141.75) × 10^(-5) / (.0625) N =

141.75 × 10^(-5) / (.0625) N

[opposite direction] =

(1.4175 × 10^(2)) × 10^(-5) / (.0625) N

[opposite direction] =

1.4175 × 10^(-3) / .0625 N

[opposite direction] =

1.4175 × 10^(-3) / 6.25 × 10^(-2) N =

14.175 / 6.25 N [opposite direction] =

2.268 N ≈ 2.27 N [opposite direction].

From hottest to coolest, the order of the spectral types of stars is _________. From hottest to coolest, the order of the spectr

Dimas [21]

Answer:

OBAFGKM

Explanation:

Most stars are classified using the Morgan-Keenan system, which consists of assigning a letter to the star depending on its temperature. The hottest stars are type O, and the coldest stars are type M. As for their color, the coldest stars tend to have red color and the hottest have blue colors.

Within each of these divisions (OBAFGKM), there is another division that are the numbers from 0 to 9: 0 is hotter and 9 colder, to get a better classification of a star.

The order of the letters of the Morgan – Keenan system classification, according to the temperatures is as follows:

O: temperatures greater than 33,000K

B: temperatures between 10,000K and 33,000K

A: temperatures between 7,500K and 10,000K

F: temperatures between 6000K and 7.500K

G: temperatures between 5,200K and 6,000K

K: temperatures between 3,700k and 5,200K

M: temperatures below 3,700 K

Assume you have four fins each with a mass of 8.0 grams what is the total weight if these four fins

irinina [24]

I do believe the answer would be 2.0 each fin because 2.0+2.0=4.0 do that twice you should get 8.0 let me know if that is correct please hope I helped
