- What is the origin of the terms “a.m.” and “p.m.” in our timekeeping?arrow_forwardShow that the acceleration of any object down an incline where friction behaves simply (that is, where fk = µkN ) is a = g(sinθ − µkcosθ). Note that the acceleration is independent of mass and reduces to the expression found in the previous problem when friction becomes negligibly small (µk = 0).arrow_forwardLet Newton's second law of motion. T, = m,a, (1) ..... T-mg = m (a- a) (2) m2g -T = m, (a+a,) (3) For movable pulley: To – 27 = 0 (a,) (4) Solve the four equations provided STEP BY STEP to get: 4mm, + m, (m - т,) a = 4m,m, + m, (m, +m, )arrow_forward
- Solve the problem in a correct way!!arrow_forwardOne of the most frequently used devices for batch fermentations is the stirred tank. The power that should be applied to the stirrer (P) is a function of its rotation velocity (N) and diameter (D), density (ρ) and viscosity of the substrate, gravityacceleration (g), and time (t) since the beginning of operation. Demonstrate using the method for dimensional analysis of your choice that the power module (Po) is a function of the Reynolds (Re) number, Froude’s (Fr) number and time module (Nt)arrow_forwardAssuming we take several trials where the total mass ?1+?2 is constant, but we redistribute themasses between ?1 and ?2. The equation you derived as your answer to the Problem (2) would apply. (a) Assume that we took these trials and plottedthe difference in the weights,??−??, on the ?-axis and the accelerationon the ?-axis. What would be the theoretical value–that is, in terms of other known quantities –of the slope?(Once again, you can think of this in terms of your equation answer to the previous problem. (b) For the same plot, what would be the theoretical value of the intercept? (c)Now consider if there were another constant force in the equation, such as friction. What would the theoretical value of the interceptbe in this case? (justify)arrow_forward
- I was able to understand the attached problem and have the answer now for mu. So the equation I have is v=150e-6.0788 x My question, then, is how do we find the TIME to slow the sled to 15 mi/hr ? The answer is supposed to be 35.533 seconds, but I don't know how to get that. Thanks!arrow_forwardCan someone please explain the answers again. And have them answered in kg m/s ??arrow_forwardPlease Answer Q3 (a), (b) and (c) step-wise with detailed explanations Thanks in advance ?arrow_forward
- This answer includes t which is not a variable provided, please answer in terms of the specified variables.arrow_forwardOne type of engine used in space travel is an ion thruster. These engines produce a low force that results in small acceleration changes. If an ion-thrust engine is used to apply 87 millinewtons [mN] of force on a satellite with a mass of 1.7 megagrams [Mg], what is the acceleration produced in units of meters per second squared [m/s2]?arrow_forwardShow that for small changes in height h, such that hRE , Equation 13.4 reduces to the expression U=mgh .arrow_forward
