Answer:
There is no change, unless your mass is somehow at the quantum level, at which the concept of half-life breaks down.
Half life is a property of the specific radioactive isotope...NOT of the initial sample's mass.
Answer:
2 Hz.
Explanation:
Frequency is simply defined as the number of appearances of a periodic event occurring per time. It is usually measured in cycles/second.
Now, in this question, we are told that there are 2 cycles for each second.
Thus, we can say that the frequency is 2 cycles/1 s = 2 Hz.
A.) Steel.
steel travels 5,060 meters per second,
lead travels 1,402 meters per second,
water travels 1,439 meters per second,
and air depends on temperature.
It depends on the tempature of something or an object,
The Object has to go from hot to cold, that is a primary example of how heat transfer occurs
<span>The speed of water in pipe is given by:
V=0.408(Q/D^2)
V=speed
Q=flow rate
D=diameter of pipe
Hence, the speed of the water is inversely proportional to square of diameter
If the speed of water through 1-cm diameter is V
Then, speed of water through 0.5 cm diameter is
=V/[(1/2)^2)]
=V/(1/4)
=4V
Hence, compared to the speed of water in 1 cm pipe, the speed in the 1/2 cm pipe is four times.</span>
