Estimated by the observer.
Take a buret, you can read to the 0.1 mL directly from the device, but the amount may lie between the 0.1 marks so you can estimate how far between the marks the fluid lies.
Answer:
Explanation:
Speed and velocity are not the same thing, as I'm sure you have determined while in physics. To find the average speed, we add the total distance run by Kiran and divide that total number of meters by the number of seconds it took to do this (just because I am going to state the speed and velocity in terms of m/s as opposed to m/min). To find the average velocity, we add the displacements together and divide by the total time. First the average speed:

Velocity has direction. If Kiran runs to the end of the road (which we will call positive) and then runs back to the start (that direction will be negative), then his displacement fits into the velocity equation as
That means, even though he ran a lot and I'm sure he was very tired, his average velocity for the trip was 0 m/s. When velocity is 0, remember that that means that the total displacement was 0.
Answer:
0.066m
Explanation:
Step one:
given
frequency =512 Hz
The speed of sound is 340.0 m/s.
Required
The wavelength
Step two:
the formula for wavelength is


substitute the given data

Because of the position on the equator, the change in rotation of the Earth on its axis throughout the year doesn't affect it much. Unlike the poles, Quito is almost constantly in direct view of the sun. So, because of lack of change in rotation, the daylight hours are hardly varied as Quito is almost constantly in more or less the same spot in relation to the sun.
