Answer:

♡ hi fairy ♡

-- The Earth's rotation is gradually slowing.

The Earth was once believed to be the centre of the universe.

Earth has a powerful magnetic field.

There is only one natural satellite of the planet Earth.

Earth is the only planet not named after a god.

The Earth is the densest planet in the Solar System.

Five different students in Mr. Garcia's class have done an experiment once, and each one got similar results. What should the st
trapecia [35]

Repeat the experiment

Explanation:

To increase the validity of the results obtained from the single experiment, the students should be encouraged to repeat the experiments more number of times as much as possible.

In an experiment, scientist always try to limit errors by making precise and accurate observation.  A single observation does not really represent a precise and accurate finding. When an experiment is repeated as often as possible, the reliability of the conclusion drawn from the hypothesis testing will improve and the results can be accepted to be valid.

A single observation/experiment is not valid enough.

How many LEDs must be combined into one light source to give a total of 3.8 W of visible-light output (comparable to the light o
notka56 [123]

Answer:

This is an incomplete question. The complete question is --

An individual white LED (light-emitting diode) has an efficiency of 20% and uses 1.0 W of electric power.

How many LEDs must be combined into one light source to give a total of 3.8W of visible-light output (comparable to the light output of a 100W incandescent bulb)?

And the answer is --

19 LEDs

Explanation:

The full form of LED is Light emitting diode.

It is given that the efficiency of the LED bulb is 20 %

1 LED uses power = 1 W

So the output power of 1 LED = 0.2 W

We need to find the power required to give a 3.8 W light.

Power required for 3.8 W = Number of LEDs required  =   (total required power  /  power required for 1 LED )

                                                                                         = 3.8 / 0.2

                                                                                         = 19

Therefore, the number of LEDs required is 19.
