Does electromagnetic radiation has mass and charge?
have, not has, and I would assume that it has electrons to be electromagnetic radiation, and therefore mass
Which came first - Phoenix or fire?
According to mythology the Phoenix (firebird) arose from the ashes of the fire. So therefore I would assume that the fire came first. :)
Would a smaller planet than earth with the same shape and size have more gravity?
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
Why did astronomers first assume that the millisecond pulsar was very young?
Because over time, pulsars and neutron stars slow down over time. The fastest ones are therefore younger.
How do you get the diameter of Mercury?
You get it by multiplying the radius by 2 or dividing circumferance by 3
How much Indian rupees make 1 billion?
General exchange conversions usually assume the reserve currency which for the most part is the US dollar (USD). Today's conversion rate is: 49.725 Indian rupees (INR) to 1 USD Therefore 1 billion USD would require 49.725 billion INR.
How many periods are there in billion?
It is now accepted in the UK that a billion is 1,000,000,000 (one thousand million), (it used to be 1,000,000,000,000 ie, one million million). We use the comma, though I believe the period is used in the USA? Therefore, where I've shown a comma, simply assume it is a period if you are in the USA!
How many billion in a trillion dollars?
1000 thousands = 1 million 1000 million = 1 billion 1000 billion = 1 trillion This is what I assume to be correct. But then again does it really matter how many billion are there in a trillion.
Why is the theme of evolution consider to be the core theme of biology by biologists?
I assume you mean evolutionary theory. Because it explains the complexity of all life and also explains all life's two main components; the unity and diversity of life.
4.5 billion years to seconds assume that there are 365.25 days per year?
Yes
1 nano second is 1 billion of a second is true?
1 nano second is actually the 1,000,000,000th of a second, or 10-9 s. It is a billion-the part of a second in the short scale, where a billion is one thousand million, or 109, but it not in the long scale, where a billion is regarded as one million million, or 1012. Billion, Trillion (and names for even larger numbers) are not universally unique. The correct answer to this question therefore is "yes, provided that you assume a short scale billion as common in most English and Arabic speaking countries. See related links for more.
What would one billion grams equal?
I assume the billion that refers to 109. Then 1 billion grams = 1 million kilograms, which equals 1000 metric tons, which is about 2.2 million pounds or 1100 tons(US).
Assume that the age of the Earth is 4.6 billion years How many half-lives of Potassium-40 does the age of the Earth represent?
Divide 4.6 billion by 1.31x109 which is the half life of Potassium-40 and you will have your answer.
Assume that the age of the Earth is 4.6 billion years. How many half-lives of Rubidium-87 does the age of the Earth represent?
Divide 4.6 billion by 5x1010 which is the half life of Rubidium 87, and you will have your answer.
What is 2 billion divided by 1000?
0.002
When do scientists assume the origin of the Earth to be?
The earth is roughly 4.5 billion years old, give or take a few 'earthdays'.
How do shared derived characters help cladistic taxonomists determine phylogenetic relationships?
Biologists hypothesize that all of the chromosomes were inherited from the same ancestor. It's possible that in one of the descendants, one chromosome became two or two chromosomes became one. Cladists will use data about physical features, embryos, genes in the nucleus, mitochondrial DNA, and ribosomal RNA. Cladisitic taxonomists take analogous features into mind, but animals are mainly classified by homologous structures. So uh, in short, a shared characteristic helps trace evolutionary history. .__.
