Answer:
Both forces act along the line joining the objects like masses or charges. And both forces are inversely proportional to the square of the distance between the objects, this is known as the inverse-square law.
Explanation:
Fluoroscopy is a type of radiography. Radiography involved the creation of images from xray exposure. Fluroscopy is usually considered to be live, regularly acquiring images. <span>Both involve X-rays. Fluoroscopy is simply X-rays in motion, as opposed to the standard hard copy of an image.</span>
Answer:
v = 112.424 km / s
Explanation:
Given:
d = 3.84 x 10 ⁸ m , R = 63 x 10³ m , m earth = 5.97 x 10²⁴ kg , G = 6.67 x 10⁻¹¹ N * m² / kg² , v₁ = 14.8 x 10 ³ m / s
Using the equation
KE + PE = initial KE + PE
¹/₂ * m * v₂² - G * m/ R = ¹/₂ * m * v₁² - G * m/(R+d)
v₂² = v₁² + 2*G * m [ 1/R - 1/(R+d) ]
v₂² = 14.8 x 10 ³ m /s + 2 * 6.67 x 10⁻¹¹ N * m² / kg² * 5.97 x 10²⁴ kg [ 1 / 63 x 10³m - 1 / ( 63 x 10³ + 3.84 x 10⁸ m ) ]
v = √ 1.26 x 10¹⁰ m² / s²
v = 112.424 x 10³ m/s
v = 112.424 km / s
In this problem, it is necessary to introduce the atomic number Z into the equation.
E=(2.18×10^-18 J)(Z^2 )|1/(ni^2 )-1/(nf^2 )| E=(2.18×10^-18 J)(2^2 )|1/(6 ^2 )-1/(4 ^2 )|=3.02798×10^-19 J
Plug the E value calculated into the equation: (wavelength is always positive)
E=hc/λ 3.02798×10^-19 J=hc/λ λ=6.56×10^-7 m
656 nm is in the visible spectrum
