The time elapsed since you stopped the stopwatch is 0.41 s.
<em>Your question is not complete, it seems to be missing the following information;</em>
"The velocity of the ant is 2 m/s"
The given parameters;
- velocity of the ant, v = 2 m/s
- change in position of the ant, Δx = 0.81 m
- time when the ant was noticed, = t₂
Velocity is defined as the change in displacement per change in time of motion of an object.

The time elapsed since you stopped the stopwatch is calculated as;

Thus, the time elapsed since you stopped the stopwatch is 0.41 s.

Answer:
A
Explanation:
It would not be C because prokaryotic cells don't have a nucleus. And if you're looking for a body in the cell that controls the nutrients and water it would be A.
A wooden log is displaced to a distance of 20m in 10 seconds by applying 500N effort . Calculate the workdone and power...
Solution,
displacement = 20 m
time = 10 sec
force = 500 N
work done = ?
power = ?
Now ,
work done = f × s
= 500 N × 20 m
= 10000 j
Now ,

Answer:
Three advantages of Reflecting Telescope over refracting Telescope:
1. there is no chromatic aberration in the Reflecting Telescope being mirror as an objective, while Refracting Telescope can suffer chromatic aberration being using lenses.
2. image of Reflecting Telescope is brighter due to large, polished curved mirrors than Refracting Telescope
3. Reflecting Telescope is compact and portable in size than Refracting Telescope.
It may be thinner and more dense? I’m not too experienced in the study of Earth’s crust. However, I know enough to remember that the earths crust is thin.
