In a simplified model of a hydrogen atom, the electron moves around the proton nucleus in a circular orbit of radius 0.53 × 10−1

For the answer to the question above,
 <span>a) Use F = k * q1 * q2 / d² 
where k = 8.99e9 N·m²/C² 
and q1 = -1.602e-19 C (electron) 
and q2 = 1.602e-19 C (proton) 
and d = distance between point charges = 0.53e-10 m 
The negative result indicates "attraction". 

b) Here, just use F = ma 
where F was found above, and 
m = mass of electron = 9.11e-31kg, if memory serves 
a = radial acceleration 

c) Now use a = v² / r 
where a was found above 
and r was given 

d) period T = 2π / ω = 2πr / v 
where v was found above 
and r was given </span>

A square has an area of 100 square meters. What is the perimeter of the square?
ser-zykov [4K]
I guess its 40 meters since 
Area of a square is (Length)^2
and The area is 100, so square root that and you get your length which is 10 meters.
and since perimeter is the sum of lengths of sides, and a square has 4 sides, your perimeter is 40 meters! :)

What’s the equation of the blue line??
Sholpan [36]

Answer:

y = -1/2 + 2 (Slope intercept)

Step-by-step explanation:

Y-intercept is when the x-value is 0.

So the y-intercept is (0, 2)

To find slope, find two random points:

(0, 2) , (2, 1)

Slope (m) =ΔY/ΔX  = -1/2 =  -0.5

Equation of the line:

y = -0.5x + 2

or

y = -1/2 + 2

When x=0, y = 2

When y=0, x = 4
