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
Which element is magnetic?
Answer
cobalt
True, it can be seen from Earth at times
Answer:
A
Explanation:
When molecules are heated they are more spread out and they move faster.
Answer:
unless acted upon by an unbalanced force.
Explanation:
If a ball is rolling, it will continue to roll forever, unless it is acted upon by an unbalanced force. For example, the friction of the floor it's rolling on slows it down. The density of the air hitting it also slows it down.
