Directly proportional to the product of the two charges and inversely proportional to the square of the distance between them
Answer:
L = 7 [cm]
Explanation:
To solve this problem we must analyze each of the distances mentioned and take into account the number of covers and thicknesses of these.
The worm crosses through the sheets of the first book, this distance can be determined by the following length analysis.
4 = P + 2*C
Where:
P = thicknesses of the pages [cm]
C = thicknesses of each cover [cm]
P = 4 - 2*(0.5)
P = 3 [cm]
The distance crossed was:
L = P + 2C + P "the pages of the first book + 2 covers + the pages of the second book"
L = 3 + (2*0.5) + 3
L = 7 [cm]
Answer:
answer is 18.6111
you can easily convert km/hr into m/s
just divide it by 3.6
Answer:
6.0 s
98 m/s
Explanation:
The radius of the planet is much bigger than the height of the tower, so we will assume the acceleration is constant. Neglect air resistance.
Acceleration due to gravity on this planet is:
a = GM / r²
a = (6.67×10⁻¹¹ m³/kg/s²) (2.7 × 1.48×10²³ kg) / (1.7 × 750,000 m)²
a = 16.4 m/s²
The height of the tower is:
Δy = 96 × 3.05 m
Δy = 293 m
Given v₀ = 0 m/s, find t and v.
Δy = v₀ t + ½ at²
(293 m) = (0 m/s) t + ½ (16.4 m/s²) t²
t = 6.0 s
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (16.4 m/s²) (293 m)
v = 98 m/s
