If the theoretical tensile strength of flawless Borosilicate Glass is 5.6 GPa, what is the maximum allowable length of an internal elliptical flaw, whose radius of curvature at the flaw tip is 5 micrometers, if the part must withstand a tensile stress of 250 MPa

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
