Answer:
what is the action and reaction ?
Explanation:
Gravitational attraction / field strength increases when closer; A light dependent resistor (LDR) can be used as a sensor to detect light intensity.
A hypothesis proposes a mechanism of change that can be tested. If the results indicate the hypothesized mechanism is not the one in operation it narrows the field and we know more. A falsified hypothesis tested by a well designed experiment still provides real evidence about the world.
<span>It was once thought that maggots spontaneously arose from carrion. This was tested and falsified providing evidence this was not how new generations of flies appeared. This still left the question of how flies generated new life to be explored. One falsified hypothesis does not block further research into the question.
</span><span>Even a failed hypothesis can increase scientific knowledge if done correctly. By knowing this hypothesis is not how something works, you save time for future scientists and can now use your effort in other investigations. That is the real value of hypothesis that are not supported by evidence.</span>
Answer:
the correct answer is A
Explanation:
In an electrical circuit the switch can be of two types: unipolar and bipolar.
The bipolar switch refers to a three-contact switch that allows the polarity in the circuit to be reversed.
The unipolar switch has only two contacts so the polarity of the circuit is in one direction and the switch serves to interrupt the passage of electrons in the circuit.
Consequently the correct answer is A
