Answer:
1. λ = 5.60 m
, 2. T = 5.80 s 3. v = 0.966 m/s 4. A = 0.315 m
Explanation:
1. The definition of wavelength is the distance between two consecutive maximums or minimums, so that the wave is repeated, in this case they give us the distance between two consecutive maximums, therefore
λ = 5.60 m
2. the period is the time it takes for the wave to start repeating itself, going through the same point. They give time to go from the highest point to the lowest point, which is the time for half a wavelength, so the time for a wavelength is
T = 2 t
T = 2 2.90
T = 5.80 s
3. For all waves the speed is the product of the wavelength by the frequency and the frequency is the inverse of the period
v = λ f
f = 1 / T
v = λ / T
v = 5.60 / 5.80
v = 0.966 m / s
4. The amplitude of the wave is the value of the zero displacement point to the maximum displacement point, give the value between the maximum and minimum displacement
A = d / 2
A = 0.63 / 2
A = 0.315 m
Answer: r^-1
Explanation:
V = (k × Q) / r, where V is electric potential, k is constant and r is distance from charge.
Since Q will not change, it can be considered a constant too.
So, we can write V ∝ 1/r
which is same as V ∝ r^-1
Answer:
The impulse delivered to the bungee jumper is 1.32 kN.s
Explanation:
The situation can be shown graphically as shown in the figure.
Impulse delivered to the bungee jumper = Area under the curve.
The curve represents a triangle and the area of traiangle = (1/2)base×height
The base of the triangle from the graph = 1.2 seconds.
The height of the triangle from the graph = 2.2 kN
Thus,
<u>Impulse = (1/2)×(1.2 seconds)×(2.2 kN) = 1.32 kN.s</u>
Explanation:
Suspension bridges, like the Golden Gate Bridge or the Brooklyn Bridge, use tension force as the primary source of force that cables use to hold their spans up. The supporting cables receive the tension forces of the bridge, and this same force passes to the anchorages and into the ground
