Answer:
7.656 m/s
Explanation:
El sonido viaja a cierta velocidad y tiene una frecuencia y longitud de onda. La relación entre la velocidad del sonido (V), su frecuencia (f) y la longitud de onda (λ) es la misma que para todas las ondas, está dada por la ecuación:
V = fλ
pero f = 1/T
∴ V = λ/T
donde T es el período
Dado que:
período (T) es el tiempo necesario para subir y bajar = 3.2 s
La distancia entre dos crestas es la longitud de onda (λ) = 24.5 m
V = λ/T = 24.5 / 3.2 = 7.656 m/s
V = 7.656 m/s
penguins! so momentum is based on mass and velocity, the advantages is that they have stored mass in the form of like fats to keep them warm however they are built to slide basically so that there is less friction when they travel so sideways their bullet like shape helps increase velocity so they have both mass and considerable velocity!

Answer:
0.167m/s
Explanation:
According to law of conservation of momentum which States that the sum of momentum of bodies before collision is equal to the sum of the bodies after collision. The bodies move with a common velocity after collision.
Given momentum = Maas × velocity.
Momentum of glider A = 1kg×1m/s
Momentum of glider = 1kgm/s
Momentum of glider B = 5kg × 0m/s
The initial velocity of glider B is zero since it is at rest.
Momentum of glider B = 0kgm/s
Momentum of the bodies after collision = (mA+mB)v where;
mA and mB are the masses of the gliders
v is their common velocity after collision.
Momentum = (1+5)v
Momentum after collision = 6v
According to the law of conservation of momentum;
1kgm/s + 0kgm/s = 6v
1 =6v
V =1/6m/s
Their speed after collision will be 0.167m/s
Answer:
a) Osmolarity measures the moles of solute per liter of solution.
Explanation:
Osmolarity is defined as the number of moles of solute that contribute to the osmotic pressure, per liter of solution, of solution. That is, the measurement of the solute concentration. The prefix "osmo-" indicates the possible variation of the osmotic pressure in the cells, which will occur when the solution is introduced into the body.
