Answer:
1) H. magnitude, 2) D. coordinates, 3) G. distance.
Explanation:
1) A vector has, by definition, both <em>magnitude</em> and direction. (Reason: Scalars have only magnitude)
2) Once you have selected a coordinate system, you can express a two-dimensional vector using a pair of quantities known collectively as <em>coordinates</em>. (Reason: Coordinates are ordered pairs)
3) Speed differs from velocity in the same way that <em>distance</em> differs from displacement. (Reason: The distance is the magnitude of displacement)
Answer:
B. an action-reaction force pair
Answer:
Digestive System
Explanation:
Food is broken down by the digestive system to give energy to the cells of the body
Answer:
854.39 N
Explanation:
The formula for the fundamental frequency of a stretched string is given as,
f = 1/2L√(T/m)..................... Equation 1
Where f = fundamental frequency, L = Length of the wire, T = Tension, m = mass per unit length.
Given: f = 261.6 Hz, L = 0.6 m, m = (5.2×10⁻³/0.6) = 8.67×10⁻³ kg/m.
Substitute into equation 1
261.6 = 1/0.6√(T/8.67×10⁻³)
Making T the subject of the equation,
T = (261.6×0.6×2)²(8.67×10⁻³)
T =854.39 N
Hence the tension of the wire is 854.39 N.
