Please help me with 1.24 I don’t know where to start and I don’t know what...
Section 1.7 Vectors and Vector Addition 1.24 For the vectors A and Figure E1.24 B in Fig. E1.24, use a scale drawing to find the magnitude and direction of (a) the vector sum A + B and (b) the vector D (10.0 m) 30.0 difference A -B. Use your answers to find the magnitude and direction of (c) -A -B5 0 and (d) B -A. (See also Exercise 1.31 for a different approach.) 1.25A postal employee drives a delivery truck...

Please help! I don't even know where to start. I know to do the sum of the forces in both directions but I'm not sure how that translates with the angle! Problem 4 (7 points). The figure below shows the positions of two α particles(each alpha particle (a) has a charge +2e) and an electron. a) Draw a clear and neat free-body diagram for either sphere at equilibrium. (2 points) b) Determine the magnitude and direction of the resultant force...
I need help to write a nice introduction for experiment 6 please ( no hands write ) typing Thank you HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...
