A 22kg box moves across a frictionless surface with a acceleration of 1.4 m/s^2 when a force is directed at 30 degrees above the horizon. What is the x component of push force? What is the applied force (hypotenuse)? What is the vertical component? What is the force of gravity? What is the normal force acting on the object?

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.)

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
