Answer:
2%
Explanation:
75% of the mass contains hydrogen 25% helium and all other elements comprising only of 2%
The time it takes "to complete one cycle" is a perfect definition for <em>period</em>.
So the <em>2 sec</em> that you measured is the swing's period.
Frequency is just 1/period (the 'reciprocal' of the period).
For this swing, the frequency is 1/(2sec) = 0.5 per second = <em>0.5 Hz</em>.
( "Hertz" means "per second")
Answer:
As the planets are very small and dark in comparison with stars, it makes them very hard to be found from earth.
Explanation:
Astronomy, of course, has a solution for this. As astronomers can't observe planets directly, they decided to observe the stars and search for the effects that planets have on them.
There are many ways of observing the exoplanets: Radial Velocity, Transit Photometry, Microlensing, Astrometry, Direct Imaging, etc.
Before all of this, scientist had to find ways to prove their theories. Most of their time they have spent in giving the creative answers.
Science and creativity are very much connected when we speak about the development of science. Rationality and creativity always go together.
In order to create an idea that other people will consider useful, it is important to use creativity. As no one has the exact answer when it comes to science, the adventure is to research the unknown.
Answer:
cultural
Explanation:
Cultural anthropology studies the characteristics of the behavior learned in human societies, that is, science of human culture. In general, it is the science that studies the origin, development, structure, characteristics and variations of human culture in both past and present societies. Ethnography, ethnology, archeology, linguistics and physical anthropology are the disciplines on which cultural anthropology is founded.
A voltmeter needs to be connected in parallel to the two sites in order to measure the potential difference between them.
<h3>What is a voltmeter?</h3>
- The electrical potential difference between two locations in an electric circuit is measured using a voltmeter.
- The potential difference between two ends of a current-carrying conductor is measured using a voltmeter.
- On a scale that is typically measured in volts, millivolts (0.001 volts), or kilovolts, a voltmeter primarily monitors the voltage of direct or alternating electric current (1,000 volts).
- Numerous voltmeters are digital and display readings as numbers.
<h3>How is a voltmeter connected?</h3>
- A galvanometer with high resistance is a voltmeter.
- Any portion of an electrical circuit can be measured.
- Due to its high resistance, it is linked in parallel so that it does not impact the circuit's overall net resistance and does not draw any current by itself.
- A device's voltage is measured by a voltmeter connected in parallel, and its current is measured by an ammeter connected in series.
