What is initial velocity measured in?

Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.


How can you use the initial value theorem to solve for the initial slope of a function?

I suggest: - Take the derivative of the function - Find its initial value, which could be done with the initial value theorem That value is the slope of the original function.


How do you find final and initial velocities with the average velocity?

You can't.You only know what half the sum of (initial + final) is, (it's the average), but you don't know what the initial and final are.


A ball is thrown straight up with an initial speed of 20 m calculate its initial speed take g10 ms-2?

Its initial speed cannot be 20 m, as stated in the question. Secondly, if the initial speed is correctly given, then there is no need to calculate it!


50 percent dextrose solution and you need a 1 percent dextrose soultion. How do you figure that out?

If the percents given are by weight or mass, this is very straightforward: The ratio between the desired percentage and the initial percentage is 1/50. Therefore, a given mass of initial solution must be diluted to 50 times its original mass to obtain the desired lower concentration, or in other words, 49 parts of diluent must be mixed with each part of initial solution. If the percents involve volume measurements, it would be necessary to take into account and change in density occasioned by the dilution.

Does coefficient of linear expansion depend on length?

No, the coefficient of linear expansion does not depend on the initial length of the material. It is a material property that remains constant regardless of the length.

Why is it necessary to weigh by difference?

Weighing by difference is necessary to accurately determine the amount of the substance being measured, as it accounts for any impurities or moisture that may be present. By subtracting the initial weight of the container from the final weight of the container with the substance, we obtain the weight of the substance itself. This method ensures the measurement is more precise and reliable.

What is steam temperature after adiabatic expansion?

The steam temperature after adiabatic expansion depends on the specific conditions of the expansion process, such as initial temperature, pressure, and volume. During adiabatic expansion, the internal energy of the steam decreases, causing its temperature to drop. The final temperature can be determined using the appropriate thermodynamic equations.
