Consider the following kinematics equation: V²₁ = V² + 2ax where Vf and V are both representative of velocities with units of [m/s], determine the proper units of 2a4x (the second term on the right-hand-side of the equals sign), such that the equation obeys the principle of dimensional homogeneity. (Include square brackets around your final answer). Typo NO
Could you possibly include a picture of the written solution, the transcription gets a bit confusing! Thank you :)
Need help on finding the values of R_k , R_0 and S . If you can show me how to solve it step by step , thanks in advance .
• One one sheet of college-lined paper, show that both sides of each of the following equations are equivalent to each other. This is a REQUIRED assignment and is not extra credit! • Start with the more complicated side on the RIGHT and try simplifying it to the LEFT side. • Take note that this is NOT an equation! So you cannot do any operation to both sides of it until you have proven both are equivalent to each other! • You may work together with your classmates but I highly recommend seeing the tutors im or myself during regularly scheduled office hours for help with this assignment. • You might need the following basic definitions of the following units: • Newton (N) = kg · m/s² • Joule (J) = N ·m = kg · m² /s? Watt (W) = Joule J sec Joule J • Volt (V) = • Ampere (A) • Farad (F) • Ohm (N) = %3D C'oulomb Coulomb sec Coulomb Volt Volt V Апрете A ||
