A bicyclist, traveling with a constant speed, covers 61.Om in 7.80s.

Physics

Answer:

<h2>The velocity is 7.82 m/s</h2>

Explanation:

In this problem, we are going to solve for the velocity since what we are given as parameters are:

1. Distance covered s= 61m

2. time taken to cover the distance t= 7.8 secs

we know that the expression for velocity is given as

velocity= distance/time

We then substitute the given data into the formula to solve for velocity.

velocity= 61/7.8

velocity= 7.82 m/s

<h2>The velocity is 7.82 m/s</h2>

Expressing Experimental Error If the accepted value of π is 3.1416, what are the fractional error and the percent error of the e
LUCKY_DIMON [66]

Answer:

1) Δx  = 0.16 m / s² ,   Δx = 9.72-9.8 = 0.08 m / s²

2)  e% = 1.63% , ,   e% = 0.816%

3)           1e% = 0.04

Explanation:

The fractional error in a quantity is the absolute error between the accepted value of the quantity and the percentage error is the fractional error per 100

In this case, it is not indicated which is the measured experimental value of pi, suppose that a value of 3.142 is measured

fractional error

                 e = (ax - ax_average) / x_average

                 e = (3.142 - 3.1416) / 3.1416

                 e = 1.27 10⁻⁴

the percentage error is

                 % = e 100

                 % = 1.27 10-4 100

                 % = 1.27 10⁻²%

1) Δx = 9.96-9.8 = 0.16 m / s²

            Δx = 9.72-9.8 = 0.08 m / s²

2) the percentage difference

 x = 9.96 m / s2

             e% = (9.96 - 9.80) / 9.80 100

             e% = 1.63%

x = 9.72 m / s2

             e% = (9.72 -9.80) / 9.80 100

              e% = 0.816%

3) the mean value is

                x_average = (x1 + x2) / 2

               x_average = (9.96 + 9.72) / 2

               x_average = 9.84 m / s2

               e% = (9.84 - 9.80) / 9.80 100

             1e% = 0.04

How could you work out the direction that the motor will turn
IgorLugansk [536]
If you mean work out as in using calculations, I don't know how to help you. But there is a way to find out, using Fleming's left hand rule. I can't define it properly, and I don't want to copy-paste from another site, so I strongly recommend that you look it up. Try google, or more specific, BBC GCSE bitesize.

Hope this helps!
