To break this problem down, let's start with what we know. The equation given finds one component of the velocity and multiplies it by the change in time. This will not find the acceleration that the first two answers say it will, meaning that the answer isn't A or B.
That leaves us with the final two answers, C and D. If the projectile was launched horizontally and we were trying to find the horizontal displacement, we wouldn't need to use cosθ to find the horizontal velocity, meaning that our answer is most likely C) <span>the horizontal displacement of a projectile launched at an angle!</span><span />
Other characteristic of radiation is the presence of positive and negative charge.
<h3 /><h3>What other characteristic does the radiation have?</h3>
Positive or negative charge are the other characteristic that is present in the radiation. Beta radiation have negative charge while on the other hand, alpha radiation have positive charge.
So we can conclude that other characteristic of radiation is the presence of positive and negative charge.

In scientific inquiry, hypothesis acts as the road map that guide the researcher and show him how to go about his scientific investigation. Hypothesis provides a testable explanation for an observation and serves as the starting point for the scientific investigation.
