1. velocidad media = desplazamiento/tiempo
desplazamiento = 0 porque el athelete vuelve al punto inicial en un círculo
velocidad media = desplazamiento/tiempo = 0/10 = 0
2. la distancia entre A y B es 5 cm porque
a^2 + b^2 = c^2 (el teorema de Pitágoras) así:
rapidez media = distancia/tiempo = 5/5 = 1 cm/s o 0.01 m/s
y yo no se cómo hacer 3-5 :( lo siento
3. Creo que es dos triángulo
s AB y CD menos la línea de fondo
5. Creo que es E + F porque B y D b y d cancelarse el uno al otro y C y C tambien pero no lo sé con seguridad.
Answer:
v = c / n (n = 1 for air)
v = c / 1.33 = 3 * 10E8 m/s / 1.33 = 2.25 * 10E8 m/s
Answer: Participating in all of the above can improve flexibility.
Explanation:
A practice that helps in improving or developing inherent power in order to bring peace and harmony to the body of a person is called yoga.
Yoga includes different postures that also help in providing flexibility to the body.
Pilates is another method of providing muscular strength and low impact flexibility to a human body.
Swimming also a good exercise that provides flexibility.
Thus, we can conclude that participating in all of the above can improve flexibility.
Answer:
• A prism is a polygon and hedron like substance [ polyhedron ] with polygonal edges hence forming rectangular, rhombical or pallarelogramic surfaces.
• There are four prism types;
- Reflecting prisms
- Dispersion prisms
- Displacement prisms
- Rotation prisms.
The final vertical velocity of the object is 705.6 m
Explanation:
Here we have to analyze the vertical motion of the object, which is a free fall motion, with constant acceleration of

towards the ground due to gravity.
Therefore, we can use the following suvat equation:

where
v is the final vertical velocity
u is the initial vertical velocity
is the acceleration
t is the time
Since the object is dropped,
u = 0
Therefore, the magnitude of the vertical velocity of the object after t = 72 seconds is:
