Answer:

C: francium-221

Explanation:

First of all to get a broader perspective, every isotope of francium usually undergoes decay to form astatine, radium, or radon.

Now, Francium-223 and francium-221 are it's only isotopes that occur in nature.

However, francium-221 is the one that undergoes alpha decay to produce astatine-217.

If the mass of a material is 124 grams and the volume of the material is 17 cm3, what would the density of the material be?
ivann1987 [24]
Mass = 124 g

volume = 17 cm³

density = mass / volume

Therefore:

D = 124 / 17

D = 7.294 g/cm³

What is a collision and how does mass affects a collision​
kompoz [17]

:)

Explanation:

A collision is the impact of 2 objects forcefully coming together in physical contact. So for example, a gold club and gold ball. The club comes in direct contact with the gold ball causing a collision. If the golf club had double the mass of the golf ball, it would result in the gold ball having twice the momentum even if they were moving at both the same speed and direction. Hope this helps explain a bit better!
