Answer:
166.8 m
30.18 m/s
Explanation:
u = Velocidad inicial del automóvil = 120 km/h =
v = Velocidad final = 0
s = Desplazamiento
a = Aceleración
t = Tiempo tomado = 10 s
De las ecuaciones cinemáticas de movimiento tenemos
La distancia que tarda el automóvil en detenerse es 166.8 m
Ahora s = 30 m
La velocidad a la que el otro automóvil sería golpeado es 30.18 m/s.
Answer:
8 m/s²
Explanation:
Centripetal acceleration formula:
- a = v²/r
- where v = velocity and r = radius
As you can see, the mass of the yo-yo is not relevant to this problem.
We are given that the velocity of the yo-yo is 4 m/s.
The radius of the circle formed by the yo-yo on a 2-meter long string is 2 meters.
Substitute these known values into the equation.
- a = (4)²/2
- a = 16/2
- a = 8
The centripetal acceleration of the yo-yo is 8 m/s².
Answer:1855
Explanation:
Virchow in 1855 published the Omnis cellula e cellula which means cells arises from Pre existing cells.Virchow used this theory that cells arises from Pre existing cells to lay the groundwork for cellular pathology
Answer:
Obviously Lengthen... or
Explanation:
As we can observe from the equation, time period of a simple pendulum depends upon the length directly. When the gravitational acceleration increases the time period of the pendulum decreases and vice versa. So, by increasing the length, the time period can be adjusted...
