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.
Bohrs atomic model only explains the atomic structure in which electrons travel around the nucleus in well-defined orbits determined by quantum conditions. A transition from a higher orbit to a lower orbit will release quantized energies of light, which would explain the light spectrum emitted by an element.
Answer:
They investigated Hooke's law.
Explanation:
This problem is pretty straight forward since we are given
the half time and we simply have to find for the rate constant. The equation
relating the two variable is:
t1/2 = ln(2) / k
where k is the rate constant, therefore:
k = ln(2) / t1/2
k = ln(2) / 14.7 h
<span>k = 0.047 / hour</span>
