Components of the force in (x1, 2,3) is given by the vector f-fsuppose that you transform to a new set of orthogonal axes '2.f'3) at the same origin but rotated by +30° about the 3 axis. what are the direction cosines, i. e., the elements of the rotation matrix rz(+30), and label them clearly as done in class? a. b. using (a), what are the components of f in (r',23), .e., what are fi? can give magnitude.) show that they are equal. d. why must the magnitude of the forces (result in (c)) be equal? e. if fi 1, f2 -2, and fa 3 (in newtons), what is the vector f and its magnitude?

Which of these describe conduction transfer of heat between two objects that are touching transfer of heat by the actual movement of war matter the process in which energy is imitated by one of the object transmitted through space and absorbed by another a process in which energy is released by the molecules breaking apart

Any color picture tube and electric field exerts a net force of magnitude 1.68x 10^-13 n on an electron the rest mass of an electron is 9.11 x 10^-13 what is the electron acceleration?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
