cells
The cell is the fundamental unit of structure and function in living things. All organisms are made up of one or more cells.
<span>Because of the location of its valence electrons, a C atom can bond in four places, rather than 1 or 2 like most elements. This allows for many different arrangements.</span>
Solution:
A frame of reference is also a system of lines and clocks that you can use to measure the position and motion of a set of objects and events in relation to each other.
It is a system of geometric axes in relation to which measurements of size, position, or motion can be made.
It might seem strange to use a coordinate system moving relative to the earth. But, for instance, the frame of reference moving along with a train might be far more convenient for describing things happening inside the train. It is particularly important when describing an object's displacement.
If the position of any one at a point O then he has a set of coordinate axes to measure the position of a body. x.y.z in units in meter. So he locates the point as x meters along x-axis , y meters long y-axis and z meters along z axis. along z axis.
These three axes are perpendicular to each other then are called orthogonal axes or frame of reference. The time of an event can be measured by a clock.
The frame is said to be attached to the observer…as his scale of measurement is his own.
By this statement that he found a body P at (x,y,z) he is locating the body in space and if the time was t then the location is in space-time.
Thus we get that changing frame of reference will affect the system of the Earth.
Answer:
so little of the uranium will have decayed within that period of time
