Total Mechanical Energy = KE + PE
KE = (1/2)mv²
= (1/2)*8*20² = 1600 J
PE = mgh g ≈ 10 m/s²
= 8 * 10 * 85 = 6800J
Total Mechanical = 1600 + 6800 = 8400 J.
To solve the problem it is necessary to apply the concepts related to Kepler's third law as well as the calculation of distances in orbits with eccentricities.
Kepler's third law tells us that
Where
T= Period
G= Gravitational constant
M = Mass of the sun
a= The semimajor axis of the comet's orbit
The period in years would be given by
PART A) Replacing the values to find a, we have
Therefore the semimajor axis is
PART B) If the semi-major axis a and the eccentricity e of an orbit are known, then the periapsis and apoapsis distances can be calculated by
Answer
given,
width of slit, d = 0.08 mm
d = 8 x 10⁻⁵ m
light of two wavelength
I₁= 446 nm
I₂ = 662 nm
a) angles at which the third dark fringe
m = 3 , I₁= 446 nm
C = 0.958°
m = 3 , I₁= 662 nm
C = 1.423°
b) angles at which the third dark fringe
m = 1 , I₁= 446 nm
C = 0.319°
m = 1 , I₁= 662 nm
C = 0.474°
As the light pass through different media, it experiences a refraction. This is a phenomenon where the speed and direction of light changes. If the ray of light moves towards the normal line, the angle is decreased. So, is the speed of that light.
No, Physical Science is the study of things you can touch, see, feel, hear, and their properties, and how they work. Physics is the rules and laws and things that abide by them.
