The question is at the picture. Answer should be round off to 2 decimal points with units.

Describe possible sources of random and systematic errors in the following measurement.   Speeds of cars recorded by a police officer using a radar gun.   Part 1 Which of the following would be random errors in this​ situation? Select all that apply.     A. Errors made by using a radar gun that is incorrectly calibrated and consistently reads high or low.   B. Errors made by the police officer in reading the radar gun.   C. Errors in the speedometers of the cars observed.   D. Errors made by the police force when choosing which officer to check the speeds.   E. Errors made when calibrating the radar gun.   F. Errors made by the police officer in recording the speeds.

please follow instruction do not do it other way follow guess method only please    Solving problems in Physics, we must always use GUESS method.Guess stands for: Guess: G Here you write down what is given in the questionUnknown: U Here you list what you have to calculate, to solve for.Equations: E here you list all the formulas you need to use to solve the problemSubstitution: S This first letter S in the word, you will just substitute what is given in theformula. You do not calculate anything. The calculations will occur at the second S: Solve. Whatis very important here is to carry with you the units of measure in the formula. Not only thenumbers. This is very important, once again.Solve: S The last step, second S, you will solve what you plugged in the first S for Substitution.Very important here is to manipulate the units of measure such that the final units of measureto be proved by your work. This part is very important, since you will allow you to verify thatwhat you do is…

2. In each measurement below, write your reading with the proper number of significant figures and uncertainty and draw the corresponding pdf. Always include units for physics quantities.

Underline the digits that are known with certainty and highlight in color the digits that are estimated. If a number is ambiguous, that is, the number of significant figures is uncertain, state so. In each case, explain your reasoning. 3) a) 4.35 m b) 0.009340 g c) 3400 km d) 1.38 x 103 m/s.

sadvantage? -One advantage to using scientific notation is that it allows you to write a large number quickly by making it "shorter". One disadvantage is that| 3. Which of the following questions are testable using scientific experimentation? Identify the dependent variable for each testable question. A. Are there more seeds in a medium-sized Red Delicious apple or a medium-sized Granny Smith apple? B. Why do people smoke cigarettes? C. What happens to your blood glucose level if you do not eat lunch? D. Which planet is the most interesting to study? E. Which objects are attracted by a magnet: a metal paperclip, a copper penny, or aluminum foil?

Pls help me answer this with solution

Determining Significant Digits Any measurement is inaccurate to some degree. The inaccuracy stems from several factors. The precision of any measuring device is limited. The person doing the measurement may introduce error. The experi- mental technique may be faulty. Because a measurement contains some degree of inaccuracy, the number of digits that are valid for the measurement are also limited. There are four basic rules that can be used to determine the number of significant digits in a mea- surement. 1. Nonzero digits are always significant. 2. All final zeros after the decimal point are significant. 3. Zeros between two other significant digits are always significant. 4. Zeros used only for spacing the decimal point are nọt significant. Suppose an observer measures the speed of an object amd determines that it is moving at 6.13 m/s. The speed of a second object is determined to be 5.02 m/s. Which digits are significant in these two measurements? According to rules 1 and 3, all the…
