Answer: 0°
Explanation:
Step 1: Squaring the given equation and simplifying it
Let θ be the angle between a and b.
Given: a+b=c
Squaring on both sides:
... (a+b) . (a+b) = c.c
> |a|² + |b|² + 2(a.b) = |c|²
> |a|² + |b|² + 2|a| |b| cos 0 = |c|²
a.b = |a| |b| cos 0]
We are also given;
|a+|b| = |c|
Squaring above equation
> |a|² + |b|² + 2|a| |b| = |c|²
Step 2: Comparing the equations:
Comparing eq( insert: small n)(1) and (2)
We get, cos 0 = 1
> 0 = 0°
Final answer: 0°

No conclusive evidence exists on “average” 1-mile run times, because there is no scientifically agreed-upon average runner. Opinion varies widely, but most anecdotal evidence places the average between seven and 10 minutes per mile for a non-competitive, in-shape runner.
= (3,760 joule/sec) / (4,000 joule/sec)
= 3,760 / 4,000 = 0.94 = 94%
Answer:
There is no exception to this. all planets have some eccentricity. it is physically impossible to have an orbit without any eccentricity. However, venus's orbit has the lowest (0.007) eccentricity (closest to circular) so that could be your answer.
Mercury's orbit's eccentricity 0.2
Venus's orbit's eccentricity 0.007 (this is the lowest so it may be your answer)
Earth's orbit's eccentricity 0.0167
Mars's orbit's eccentricity 0.0934
Jupiter's orbit's eccentricity 0.0489
Saturn's orbit's eccentricity 0.0565
Neptune's orbit's eccentricity 0.009
Uranus's (yur,in,iss) orbit's eccentricity 0.0457
Pluto's (not really a planet) orbit's eccentricity 0.2444 (very high)
hope it helped.
