Rubidium 87 has a half life of 49 billion years so it would be 3 half lives. There should, therefore be 1/8 remaining.
However, it is believed that the universe is less than 15 billion years old. So finding any object that is 147 billion years old is - to put it mildly - totally impossible!
What else can I help you with?
Divide 1 billion billion dollars by 6 billion?
a billion billion is 1,000,000,000 x 1,000,000,000 i.e. 1,000,000,000,000,000,000, A quintillion I would say. divided by 6 billion is 16,666,666.67 dollars
How many zeros in 850 billion?
In American usage 1 billion is 1,000,000,000 - so there would be 10 zeroes in 850 billion. In England, and some other countries, 1 billion is 1,000,000,000,000, so there would be 13 zeroes in 850 billion.
How many zeros in 17.4 billion?
17.4 billion would be written out as 17,400,000,000. So it would be 8 zeroes. A billion has 9 zeroes and a million has 6 zeroes.
What does the number 1.4 billion look like?
The number 1.4 billion can be visualized as 1,400,000,000. This number is equivalent to 1.4 thousand million or 1.4 x 10^9. In terms of physical objects, if each object represents one unit, you would need 1.4 billion objects lined up in a row to represent this number visually.
How do you write 300 billion?
To write 300 billion, you would start with the number 300, followed by the word "billion." In numerical form, this would be written as 300,000,000,000. This number represents 300 multiplied by 1 billion, where 1 billion is equivalent to 1,000,000,000.
What would happen if an object is immersed in a fluid and the object and the fluid had the same density?
The object would behave as a part of fluid and it will remain where it is kept.
Would a 0.85g object float sink or remain suspended in tap water?
That depends entirely on the volume of the object
What would happen to the mass of an object if you took it to the deepest valley on earth?
It will remain the same.
Would there have to be an Unbalanced force acting on moving object?
There would have to be an unbalanced force put an object in motion but once in motion no force is necessary for it to remain in motion
Can an object that has balanced forces acting on it be standing still?
Yes, an object can be standing still when there are balanced forces acting on it. In this case, the net force on the object is zero, so there is no acceleration causing the object to move. The object will remain at rest or in a state of constant velocity.
Is it true that if at any time the forces are unbalanced an object will remain at rest?
No, if the forces acting on an object are unbalanced, the object will either remain at rest or continue to move at a constant velocity. It is only when the forces are balanced that an object at rest will remain at rest.
How long would it take to count one billions objects weighed 0.00000001 gram?
To count one billion objects, it would take you however long it takes to count one object times one billion. It does not matter how much mass the object has, so your statement of mass is meaningless.
What would be the effect on the mass and the weight of an object if the object were taken to to a planet with twice the gravity of earth?
The mass of the object would remain the same, as it represents the amount of matter within the object. However, the weight of the object would double on the planet with twice the gravity of Earth because weight depends on the gravitational pull experienced by the object.
If a force of 90 Newtons was exerted on an object and no work was done would the object gain momentum?
No, since work is required for an object to gain momentum. In this case, if no work was done (work=force x distance), then the object would not gain momentum despite the force being exerted on it.
How can an object be moving if there is no unbalanced force on it?
Unbalanced forces cause acceleration, not movement. An object can move at a constant speed with no net force acting on it. An example would be an object falling at terminal velocity.It would have to have been already moving. Newton's First law states that an object at rest will remain at rest and an object in motion will remain in motion with the same speed and direction unless it is acted upon by an unbalanced force. The second part of the law explains this.
Would an object have the same mass density on the moon as it does on earth?
No, the mass density of an object would not be the same on the moon as on Earth. The mass of the object would remain the same, but since the gravitational pull on the moon is weaker than that on Earth, the volume of the object would decrease on the moon, resulting in a different mass density calculation compared to Earth.
What is the amount of matter that an object has if the object were on the moon this would not change?
The amount of matter an object has, also known as its mass, would remain the same whether the object is on the moon or on Earth. Mass is an intrinsic property of an object and is independent of the object's location. However, the object's weight (the force of gravity acting on it) would be different on the moon compared to Earth due to the moon's lower gravity.
