Problem:
Power required to accelerate 1000 kg car from 0 to 60 mph ( 26.82 metres / second) in 3 seconds ?
>
kinetic energy gained (energy change)= 0.5 * mass * velocity2,
>
so 0.5 * 1000 * 26.822 = 359656.2 joules
>
Power required = energy change / time taken
= 359656.2 / 3
= 119885.4 joules / second (watts)
= 119.8854 kw (about 161 bhp)

What are the sample problems for graphical and analytical method?
Graphical method sample problem: Find the solution to the system of equations: 2x + 3y = 12 x - y = 3 Analytical method sample problem: Solve the system of equations using substitution method: 3x + 2y = 11 4x - 5y = -7
What variables affect power?
Variables that affect power in a statistical test include the sample size (larger sample sizes increase power), the effect size (larger effect sizes increase power), the significance level (higher significance levels increase power), and the variability in the data (less variability can increase power). Additionally, the chosen statistical test and the presence of confounding variables can also impact the power of a study.
Why do microscopes always need to be turned on at low power?
If you mean magnification, unless you have a confocal microscope, the objective lens with the lowest mag will be the shortest -- largest clearance between the bottom of the lens and the stage. You can easily load and unload (slide in or out) the sample off the stage. If the reason is the above, I have a better way. I always load the sample with the lens rotated away -- the best clearance will be when no lenses are in position. If so, I would have lowered the stage quite a bit so that when I swing the lens in position, I am not scratching the sample. However, a better reason for starting with low mag would be that you can focus much easier with the lowest-mag lens and then refocus to go to a higher mag -- the sample is approximately in focus all these times. When the sample is way out of focus, as when the highest-mag lens is on when you first insert the sample, it is hard to know which direction to turn the focus knob without scratching the sample.
Which of th following is true when using the higher-power objective on a light microscope?
When using the higher-power objective on a light microscope, the magnification of the image is greater, allowing for better resolution and finer details to be observed. However, the field of view is reduced, meaning that less of the sample can be seen at one time. Additionally, the depth of field is shallower, requiring more precise focusing to visualize different layers of the sample.
What is the formula for calculating the mean of a sample, represented by the symbol "" in statistics?
The formula for calculating the mean of a sample, represented by the symbol "" in statistics, is to add up all the values in the sample and then divide by the total number of values in the sample. This can be written as: x / n, where x represents the sum of all values in the sample and n is the total number of values in the sample.
