Answer:
C
Explanation:
Radiation affects both cancer cells and healthy cells, but it affects cancer cells more.
Answer:
0.385 meters
Explanation:
Just remember this very simple equation:
velocity=(wavelength)*(frequency)
I always remember it as "Velma is Waving Frantically"
So, 125=(wavelength)*(325)
Therefore, wavelength=0.385 meters!
Hope this helped!
Answer:
Explanation:
The law of conservation of mass states that the mass of the elements at the beginning of the reaction(reactants) will equal the mass at the end of the reaction (product) .
In the chemical equation above,the total mass of the reactants is 80g(16+64) and the total mass of the products is also 80g(44+36).therefore the mass remained constant and that's how the equation represents the law of conservation of mass
40 miles/hour
Details:
after one hour they have traveled 40mi. So they have traveled 40mi. in 1hr, or 40mi/1hr or 40mi/hr.
the problem is about reading a graph. the graph says that they traveled 40 miles in the first hour
formula for average speed:
miles traveled/time it took=speed or d/t=r
