Answer:
B) A drawn bow is released, causing an arrow to fly across the field
Explanation:
Potential energy can be thought of as "potential" to do something. For eg, putting a ball on top of hill causes the ball to have the potential to roll down the hill if released. Here the ball converts the potential energy into kinetic energy (energy of motion) to roll down.
Similarly, the bow has been stretched (potential to fly if released), and when its released, it converts the potential energy into kinetic energy.
Answer:
Recibir y analizar la información y producir respuestas.
Explicación:
Las principales funciones del sistema nervioso es recibir información del entorno externo y produce respuestas a la información recibida. El sistema nervioso comprende el cerebro y la médula espinal que controla todo el cuerpo. hay células sensoriales presentes en la piel que reciben estímulos externos y a través de las neuronas la información se transfiere al sistema nervioso. después de procesar la información, la respuesta se envía a los músculos para que actúen frente a los estímulos externos.
Answer:
Th is the symbol for element Thorium.
Mg is magnesium while Mg 2+ is magnesium Ion. Judging from periodic trends, atomic radius is one half the distance between the atoms of two covalently bonded atoms. It decreases as elevtrons are added to valence shells. That means, across the period it increases and down the group it decreases. Making Mg2+ smaller.
Electronegativity is the energy needed to take an electron in the gaseous state. Florine is more electron negative that lithium. It increases across the period and decreases down the group. Except in the Noble group.
Explanation:
The results of this experiment gave Rutherford the means to arrive at two conclusions: one<span>, an atom was much more than just empty space and scattered electrons and </span>two<span>, an atom must have a positively charged center that contains most of its mass (which Rutherford termed as the </span>nucleus<span>).
