Explanation:
It is given that,
Speed of the person, v = 3 mile/hr = 1.34 m/s
Speed of the truck, v' = 65 mile/hr = 29.05 m/s
(a) Since, 
For the person, 
For the truck, 
(b) The relativistic factor is given by :
For very small velocity, 
For the person :
For the person :
Hence, this is the required solution.
By testing it out. Try it.
Answer:
8.46E+1
Explanation:
From the question given above, the following data were obtained:
Charge 1 (q₁) = 39 C
Charge 2 (q₂) = –53 C
Force (F) of attraction = 26×10⁸ N
Electrical constant K) = 9×10⁹ Nm²/C²
Distance apart (r) =?
The distance between the two charges can be obtained as follow:
F = Kq₁q₂ / r²
26×10⁸ = 9×10⁹ × 39 × 53 / r²
26×10⁸ = 1.8603×10¹³ / r²
Cross multiply
26×10⁸ × r² = 1.8603×10¹³
Divide both side by 26×10⁸
r² = 1.8603×10¹³ / 26×10⁸
r² = 7155
Take the square root of both side
r = √7155
r = 84.6 m
r = 8.46E+1 m
“Inner Planets” – Mercury, Venus, Earth, and Mars – which are so named because they orbit closest to the Sun. ... For starters, the inner planets are rocky and terrestrial, composed mostly of silicates and metals, whereas the outer planets are gas giants.
Practically yes
So
If mass is more output may come less so it affects the efficiency practically
But thepritically it doesn't
