Calculating Velocity

m_a_m_a [10]

The average velocity of the object represented by the distance time graph is $0.1\:meter\:per\:second$

The velocity of an object is the change in the distance moved by an object with time.

This could also be related to the rate of change or slope of the graph.

Average velocity = $\frac{change\:in\:distance}{change\:in\:time}$

Average velocity = $\frac{(5-0)}{(50-0}) = \frac{5}{50}=0.1\:meter\:per\:second$

Therefore, the average velocity of the object is $0.1\:meter\:per\:second$

Which description matches up correctly with each type of particle? Alpha - no mass and no charge; beta - mass of 4 and charge of

Veseljchak [2.6K]

The closest answer is
Alpha - mass of 4 and charge of +2; beta - no mass and charge of -1; gamma - no mass and no charge (consists of energy)

It’s not exactly correct because a beta particle has the (small) mass of an electron (also the positron). All other choices are way off, I’d go with this one.
