An iron pendulum clock keeps correct time at 20°C. How many seconds will it loose or gain per day when temperature is increased to 30°C?(given, linear expansivity of iron=12×10^-6 per kelvin?

c.the charges if the proton and electron and gravity

what is the instantaneous acceleration of

the particle at point b?

0 meters/second?

10 meters/second?

12 meters/second?

velocity imetersisecond

15 meters/second?

20

time (seconds)

answer: 0 meters/second^2

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
