To give a sense of scale in a photograph of a mountain you could include something static like a 1 story house, a car, or even a human being for scale.
Answer:
17.00 N
Explanation:
Given that the x-component of a vector is 17, and the angle between the vector and the x-axis is 46 degrees
The magnitude of the vector will be calculated by first resolving the vector into x component and y component.
X - component
17cos46 = 11.809
Y component
17sin46 = 12.229
We will find the resultant vector by using pythagorean theorem
R = sqrt ( X^2 + Y^2 )
R = sqrt ( 11.809^2 + 12.229^2 )
R = sqrt ( 288.995 )
R = 16.999
R = 17.00 N
Therefore, the magnitude of the vector is 17 .00N
Then the speed of the rider is, v = 2m/s
The linear velocity of an object in a straight line is its speed.
The following is the relationship between linear and angular velocity:
v = rω
The circumference of the bicycle wheel is,
2r = 2
r = 0.318m
The angular velocity of the wheel is,
ω = 1rev/sec = 2rad/s
Then the speed of the rider is,
v = rω
v = 0.318×2π
v = 2m/s

The answer is B preserve the front wheel alignment.
Answer:It increases confidence because the more times you conduct the same experiment over and over should either prove your hypothesis right and wrong and eliminate any random occurrences that might affect your results.
