I thought that the coefficient of linear thermal expansion would
be what is given already...please help.
Now the friends use data obtained in the simulation to identify materials A-E. They calculate and record the value of α for each material and use the table below to identify it. (Hint: The simulation rounds some of the data to two-digit accuracy, so calculate all coefficients of linear thermal expansion using AT 50.)

A proton accelerates from rest in a uniform electric field of 600 N/C. At one later moment, its speed is 1.30 Mm/s (nonrelativistic because v is much less than the speed of light) (a) Find the acceleration of the proton 5.74e10m s2 (b) Over what time interval does the proton reach this speed? Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation, carry out...
