Answer:
False
Explanation:
It depends on the density of an object, not the wight.
in the case of beryllium, a light metal, only the beryllium-9 isotope is stable with its 9 nucleons (i.e. 4 protons and 5 neutrons)
Hope this helps so sorry if it does not help
Gamma waves have the highest frequencies and shortest wavelengths
<span>C: 8 cm
Assuming no friction, since the ball is starting with an elevation of 20 cm, it will end up with an elevation of 20 cm. So let's just calculate the result.
"slope of 5 cm of rise for each 2 cm of run". So for every 5 cm the ball rises, it will go 2 cm horizontally. Since we know the ball will have a total rise of 20 cm, that gives us
20 cm / 5 cm * 2 cm = 8 cm
And looking at the available answers, 8 cm is sitting right there. So the answer is
C: 8 cm</span>
A scalar<span> is a quantity that is completely specified by its magnitude and has no direction. A scalar can be described either dimensionless, or in terms of some physical quantity.
the answer for this case is
</span><span> average speed
</span><span>time interval</span>
