Q1. A staging that weighs 140N supports two painters, one 320N and the other 420N. The reading in the left scale is Fl = 610N. What is the reading Fr in right hand scale?
Q2. A loudspeaker of mass 18.0 {rm kg} is suspended the distance of h = 1.20 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 2.70 {rm m}. What is the tension T in each of the cables? Utilize 9.80 {rm m/s}^2 for the magnitude of the acceleration because of gravity.
What is constant speed V
Assume that the rod is held at rest horizontally and then released. (Throughout the remainder of this problem, your answer may include the symbol, moment of inertia of the assembly, whether or not you have answered the first part correctly.)
From what height will you have to drop the rock on Earth so that the fall-time on both planets is the same.
Three single-phase step-up transformers rated at 10MVA, 4.6kV/13.8kV are connected in Wye-Delta configuration. The three transformers are used to feed a 20MVA load at 0.9 p.f. With an efficiency of 96%. Find the secondary line voltage.
One hundred k mol of a gas containing 94.4 mole% methane, 3.40% ethane, 0.60% propane, and 0.50 percent butane is to be burned with 17% excess air. Calculate the required molar flow rate of the air.
Six artificial satellites complete one circular orbit around a space station in the same amount of time. Each satellite has mass and radius of orbit. The satellites fire rockets that provide force needed to keep a circular orbit around the space stat..
Conclude the magnitude of angular acceleration
Soccer ball is kicked with a speed of 11.50 m/s at an angle of 30.0° above the horizontal. If the ball lands at the same level from which it was kicked, how long was it in the air.
A 75-kg person sits on a 3.7-kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.5 cm in diameter. Find out the pressure exerted on the floor by each leg of the chair; assume the weight is evenly distributed.
What is the direction of proton after the collision? What is the direction of carbon atom after the collision.
A 38.0 kg child swings in a swing supported by two chains, each 3.04m long. The tension in each chain at the lowest point is 429N. Find out the child's speeds at the lowest point.
A 37-kg girl is bouncing on a trampoline. All through a certain interval after she leaves the surface of the trampoline, her kinetic energy decreases to 215 J from 430 J. How high does she rise during this interval? Avoid air resistance.
