Students in Dr. Branch's physics class were calculating the average time required for one complete period of a pendulum bob. They set up five pendulums and timed the swing for each one twenty-five
times. Then they calculated the average period time.
One set of data varied significantly from the other sets. What could be one source of unavoidable
error that influenced the data?
Select one:
a. Not starting the timer at exactly the "go" call.
O b. Reading the stopwatch incorrectly.
O c. Stopwatch starts with one second on the clock.
O d. Students not paying attention to data collection

answer; i believe the correct answer is (data); /// good luck

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!

it should be d) transitional fossils.
