The value is
Explanation:
From the question we are told that
The speed of the marathon runner is
The distance from the distance from the finish is
The speed of the bird is
Generally the time taken for the runner to reach the finish is mathematically represented as
So the distance covered by the bird is
Explanation:
|F|= B/2
B/2 = √(A²+B²+2ABcosθ) ------(1)
Since the resultant of A and B is perpendicular to Vector A
tan90°= BSinθ/(A+BCosθ)
(A+BCosθ)=0
Cosθ=-A/B ----(2)
Using equation (1)
B/2 = √(A²+B²+2ABcosθ)
B/2 = √(A²+B²+2AB×-A/B)
B/2=√(A²+B²-2A²)
B/2=√(B²-A²)
B²/4=B²-A²
A²=B²-B²/4
A²=3B²/4
A=√3B/2
Using equation (2)
Cosθ=-A/B
Cosθ=-[√3B/2]/B
Cosθ=-√3/2
θ= cos^-1 (-√3/2)
θ= 150°
Two or more variables considered to be related, in a statistical context, if their values change so that as the value of one variable increases or decreases so does the value of the other variable (although it may be in the opposite direction).
And the degree to which two variables vary together determines whether the relationship is strong or weak
The lower limit that could be used to determine the position of each object along the direction of the velocity is 1.136 x 10⁻³ m.
<h3>
Uncertainty in the position of the electron</h3>
The uncertainty in the position of the electron is calculated as follows;
where;
- h is Planck's constant = 6.63 x 10⁻³⁴ Js
- m is mass of electron
- Δv uncertainty in velocity = (0.01 x 10⁻²) x 510 = 0.051 m/s
Thus, the lower limit that could be used to determine the position of each object along the direction of the velocity is 1.136 x 10⁻³ m.
