It takes a longer wavelength
Answer:
Miller Indices are [2, 4, 3]
Solution:
As per the question:
Lattice Constant, C = 
Intercepts along the three axes:
Now,
Miller Indices gives the vector representation of the atomic plane orientation in the lattice and are found by taking the reciprocal of the intercepts.
Now, for the Miller Indices along the three axes:
a = 
b = 
c = 
To find the Miller indices, we divide a, b and c by reciprocal of lattice constant 'C' respectively:
a' = 
b' = 
c' = 
Answer:
Coefficient of kinetic friction = 0.146
Explanation:
Given:
Mass of sled (m) = 18 kg
Horizontal force (F) = 30 N
FInal speed (v) = 2 m/s
Distance (s) = 8.5 m
Find:
Coefficient of kinetic friction.
Computation:
Initial speed (u) = 0 m/s
v² - u² = 2as
2(8.5)a = 2² - 0²
a = 0.2352 m/s²
Nweton's law of :
F (net) = ma
30N - μf = 18 (0.2352)
30 - 4.2336 = μ(mg)
25.7664 = μ(18)(9.8)
μ = 0.146
Coefficient of kinetic friction = 0.146
Answer:
= 3521m/s
The tangential speed is approximately 3500 m/s.
Explanation:
F = m * v² ÷ r
Fg = (G * M * m) ÷ r²
(m v²) / r = (G * M * m) / r²
v² = (G * M) / r
v = √( G * M ÷ r)
G * M = 6.67 * 10⁻¹¹ * 5.97 * 10²⁴ = 3.98199 * 10¹⁴
r = 32000km = 32 * 10⁶ meters
G * M / r = 3.98199 * 10¹⁴ ÷ 32 * 10⁶
v = √1.24 * 10⁷
v = 3521.36m/s
The tangential speed is approximately 3500 m/s.
Melting of ice caps ... causing them to shrink in coverage .. can result in ...
-- wet ground
-- more farming opportunities, but less skiing
-- higher sea level
-- coastal flooding
-- extinction of plant and animal species
-- more icebergs floating around
-- lower average albedo, higher solar absorption, widespread warming
