DENIUS [597]

Explanation:

A particle that contains two protons and two neutrons bounded together is known as an alpha particle.

It is known that an alpha particle has a large mass and due to this they travel very slowly. As a result, they tend to have low velocity.

Hence, we can conclude that alpha particles cannot penetrate deeply into solids because they have low velocity.

Arrange the following measurements, in seconds, from the greatest bias to the least bias. 6.63 ± 0.01 s, 6.6 ± 0.1 s, 6.52 ± 0.0
lord [1]
I understand here "bias" to be the uncertainty of measurements. So the order will be the following:

6.4 ± 0.5 s
<span>6.6 ± 0.1 s,
</span><span>6.63 ± 0.01 s,
</span><span>6.52 ± 0.05 s,
</span>
(notice how the second number, the one behind the symbol ± gets smaller, as the bias gets smaller).
