Given parameters:
Volume of water in the tank = 750litres
Length of the tank = 150cm
Breadth of tank = 50cm
Unknown:
Height of the tank = ?
To solve this problem, we must understand the concept of volume. Volume is a property of solid bodies. It is mathematically derived as:
Volume = length x Breadth x height
The unknown here is the height and we should go ahead to solve for it.
<em>But the units are inconsistent. </em>
Therefore, convert litres to cm³;
1 litre = 1000cm³
750 litres = 1000 x 750 = 750,000cm³
Now input the parameters and solve for the height;
750000 = 150 x 50 x height
height = = 100cm
Therefore, the height of the tank is 100cm
C. Making spikes on shoes because it doesn’t cause friction (i think)
Answer:
La velocidad de la onda es 5 m/s.
Explanation:
La velocidad de la onda puede calcularse como:
(1)
Donde:
λ: es la longitud de onda de la ola = 15 m
T: es el período = 3 s
Entonces, reemplazando los valores de T y de λ en la ecuación (1) tenemos:
Por lo tanto, la velocidad de la onda es 5 m/s.
