What is the speed of a car going v=1.000mphv=1.000mph in SI units? Notice that you will need to change from miles to meters and from hours to seconds. You can do each conversion separately. Use the facts that 1mile=1609m1mile=1609m and 1hour=3600s1hour=3600s.

Suppose that a person has an average heart rate of 91.0 beats/min. (Express your answers to problems in this section to the correct number of significant figures and proper units.) How many beats does he or she have in 6.0 y? How many beats does he or she have in 6.00 y? How many beats does he or she have in 6.000 y?

Trying to convert 1.40mi into kilometers but still havent quite mastered the unit conversion. I tried 1.40mi * (1.609km/1mi) but thats not correct. Please assist me with this

Question 1 Make the conversion of 2.4 Km/h2 to m/s2. O 6.67 E(-4) 1.85 E(-4) 1.85 E(-7) 0.67 1.5 Question 2 In solving a physics problem you end up with m in the numerator and m/s in the denom units for your answer are O m/s O m^2/s O m O 1/s Question 3

An electron is traveling at 5×105 m/s when it is 3 nm away from a proton. What is the speed of the electron if it escapes the proton to a location far away from it?

Five clocks are being tested in a laboratory. Exactly at noon, as determined by the WWV time signal, on successive days of a week the clocks read as in the following table. Rank the five clocks according to their relative value as good timekeepers, best to worst. Give the number of the correct clock in each case. Which clock is (a) the best timekeeper? (b) the second-best timekeeper? (c) the third-best timekeeper? (d) the fourth-best timekeeper? (e) the worst timekeeper? Clock Sun. Mon. Tues Wed. Thurs. Fi. Sat.

I1:00:00 PM Problem 3: Suppose the speed of light were only 3000.0 m's. A jet fighter moving toward a target on the ground at 810 m/s shoots bullets, each having a muzzle velocity of 1050 m's. Randomized Variables v-810 m/s v2 1050 m's ed What is the velocity of the bullets relative to the target in km's? Grade Sommary Deductions 0% Potential 100%

That's what I thought too! But the answer choices it gave were 8 m/s, 4 m/s, 2 m/s, and 6 m/s so I'm confused. I went with 8 and it was wrong.

A biologist studies a species of bacteria called FAST, her research reveals that FAST bacteria reproduced prodigiously. If a bacteria culture contains 10 FAST bacteria at time t= 0, the number of FAST bacteria in the culture later time 't' is N(t) = 10 +6t +2t2 where 't' is expressed in seconds.  How many bacteria occupy the culture a time t = 10s?  At t =11s? Calculate how many net bacteria were born during the interval between t=10 and t=11, assume no bacteria died.  Now use calculus to find the birth rate of bacteria (rate at which new bacteria get born) at time t=10s, it may help to sketch a rouch graphy of N vs 't'.
