What is the rate of acceleration of a 2,000-kg truck if a force of 4,200n is used to make it start moving forward

Acylindrical specimen of a nickel alloy having an elastic modulus of 207 gpa (30 × 106psi) and an original diameter of 10.2 mm (0.40 in.) experiences only elastic deformation when a tensile load of 8900 n (2000 lbf) is applied. compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in.)

How have the competing explanations' experiments on atoms affected the development of the atomic model?

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
