Answer:
voltaje = 24 Volts
Explanation:
dados los siguientes parámetros;
resistencia = 12Ω
corriente consumida = 2 A
Para encontrar el voltaje;
La ley de Ohm establece que a temperatura constante, la corriente que fluye en un circuito eléctrico es directamente proporcional al voltaje aplicado en los dos puntos e inversamente proporcional a la resistencia en el circuito eléctrico.
Matemáticamente, La ley de Ohm viene dada por la fórmula;
voltaje = corriente * resistencia
voltaje = 2 * 12
<em>voltaje = 24 Volts</em>
<em>Por tanto, la tensión que se debe suministrar al motor eléctrico es 24 Volts. </em>
Answer:
Talking louder
Explanation:
The deaf cant hear. Many people think if they can speak louder or closer to them they can hear. That is not the case.
Transport long ago was very slow and could take weeks to get places sometimes but transport today we can get places a whole lot faster
Answer:
True.
Explanation:
Indeed, the main purpose of technology is to take our communication and our everyday functioning to another level. The last century's progress and modernization were inevitable. Technology growth is extremely fast and unstoppable. Like any kind of advance, the basic intention is always to develop humanity and perfect it.
Technology made global communication faster, easier, cheaper and more accessible. We are now able to talk to someone who is thousands of miles away or to see live broadcasts. Not to mention what did satellites, GPS or Google, for example.
More specific kind of technology meets high-level needs. Assistive technology helps people with disabilities function without much difficulty. There is no doubt technology made our lives easier.
However, when there is much use, there is also much abuse. Every day, we are victims of stealing, lying, offending, etc. on the internet. People found a way to misuse technology in order to achieve their goals. Think of hackers that can easily rob a bank, think of all fake profiles on social media or data theft. These are just basic examples of technology abuse, which ought to be controlled as much as possible.
