Answer:
U = 8.30×10-⁹J
Explanation:
m1 = m2 = 5.00kg masses of the spheres
d = 15.0cm = 15×10-²m
r = 5.10cm = 5.10×10-²m
R = d + r = 15×10-² + 5.10×10-²
R = 20.10 ×10-²m = 0.201m
G = 6.67×10-¹¹Nm²/kg²
U = Gm1×m2/R = potential energybetween the spheres
U = 6.67×10-¹¹×5.00×5.00/0.201
U = 8.30×10-⁹J
Answer:
Wavelength of light is 600 nm
Explanation:
Given
Distance between the first order maximum and the tenth order maximum of a double-slit pattern = 18 mm
Separation between the slits = 0.15 mm
Distance of screen from the slits = 50 cm
Wavelength
nm
The subatomic particles found in the area surrounding the nucleus of an atom are called electrons.
<span>So we want to know what physical quantity represents the wavelength of a wave. Waves have a few phyiscal quantities that are used to describe them. Frequency, amplitude and wavelength. Frequency is the number of oscillations in a specific time interval, amplitude is the maximal elongation of a wave and wavelength is the distance from one point ona a wave to the next similar point. So the correct answer is B. </span>
