Answer = 6.24x10^18 x ((2 x 3600) + (47 x 60) + 10)
Answer:
Acceleration = 9 × 10^5 m/s^2 ( deceleration )
Explanation:
From the first equation of motion:
V = u + at
15000 = 30000 + 60a
a = ( 15000-30000)/60
a = 9 × 10^5 m/s^2
Answer:
Y = 3.87 x 10⁻³ m = 3.87 mm
Explanation:
This problem can be solved by using Young's double-slit experiment formula:

where,
Y = fringe spacing = ?
L = slit to screen distance = 2 m
λ = wavelength of light = 580 nm = 5.8 x 10⁻⁷ m
d = slit width = 0.3 mm = 3 x 10⁻⁴ m
Therefore,

<u>Y = 3.87 x 10⁻³ m = 3.87 mm</u>
Answer:
c large, spherical body that orbits in a clear path around a star
Explanation:
you can not say b because the sun is a star and you cant say a and d because all planets are not made of rock and all planets are not made of gas
