It could combine with any other metal on the periodic table. If I had answers to choose from, then maybe I could help you better.
Hope this helps!!!
Answer:
a). la acelaración del automóvil es
b). la distancia recorrida por el automóvil es
La aceleración puede ser encontrada por medio de la ecuación cinemática que corresponde a un movimiento rectilíneo uniformemente variado.
(1)
Donde es la velocidad final y es la velocidad inicial.
La velocidad inicial del automóvil sera cero () ya que parte del reposo.
Antes de remplazar los valores en la ecuación 1 es necesario expresar el tiempo en unidades de segundos.
⇒
La rapidez final puede ser expresada en unidades de :
Por lo tanto, la acelaración del automóvil es
Luego para calcular la distancia se puede utilizar la siguiente ecuación.
(2)
Por lo tanto, la distancia recorrida por el automóvil es
A sound wave leaves the loudspeaker. As it travels, it experiences a temporary increase in wavelength and then returns to its original wavelength. The sound wave traveled through a helium balloon (helium is less dense than air could explain this change in wavelength
The pattern of disruption brought on by energy moving away from the sound source is known as a sound wave. Longitudinal waves are what makeup sound. This indicates that the direction of energy wave propagation and particle vibrational propagation are parallel. The atoms oscillate when they are put into vibration.
A high-pressure and a low-pressure zone are created in the medium as a result of this constant back and forth action. Compressions and rarefactions, respectively, are terms used to describe these high- and low-pressure zones. The sound waves go from one medium to another as a result of these regions being transmitted to the surrounding media.

A chemical change. chemical changes could cause changes in shapes or sizes
Speed of the black Mamba = 18 km/h = 5m/s
now the distance that black mamba cover to catch prey
Now it returns to its hide in 12 s
so average speed of return is given as
Part b)
For the whole trip we know that displacement of the mamba is zero
so average velocity of whole trip will be zero
Part c)
For average speed we know that total distance of the black mamba
d = 12.5 + 12.5 = 25 m
total time taken = 2.5 + 12 = 14.5 s
now average speed is given as
