Q1. A small aircraft experiences s lift force equal to 3.80 times of its weight.
a) illustrate a diagram to show the forces acting on the aircraft while it is flying in a horizontal circle with its wing banked at an angle to horizontal
b) find out the maximum bank angle that the aircraft can safely maintain without threatening the safety of the aircraft
Q2. What will happen to the amplitude of the current in the LRC circuit when frequency of the applied voltage is at or near the resonant frequency of circuit? Explain?
Estimate how many times planet has orbited its star
A 3 kg object id released from rest at a height of a 5 meter curved frictionless ramp. At the foot of the ramp is a spring force constant of k= 400n/m the object slides down the ramp and onto the spring compressing it to the distance x before comi..
A surface is infinitesimally close to and surrounds a dipole. The electric flux during the surface must be zero, since the net charge it surrounds is zero. How is it possible for the dipole to have an electric field and be consistent with Gauss' t..
Inversely proportional to the square of the fields
A 1500 kg car carrying four 87kg people travels over a rough "washboard" dirt road with corrugations 4.40 m apart which causes the car to bounce on its spring suspension. The car bounces with maximum amplitude while its speed is 19km/h. The car now s..
You are to program a robotic arm on the assembly line to move in a xy-plane. Its first displacement is; its second displacement is, of magnitude 6.51 and direction 62.7 measured in the sense from +x-axis toward -y-axis. The resultant of the two displ..
The acceleration of gravity is 10 m/s2. What is the acceleration of a 39 kg pail of cement that is pulled upward (not sideways) with a force of 421 N? Answer in units of m/s2.
Two ocean liners, each with a mass of 38,000 metric tons, are moving on parallel courses, 92 m apart. What is the magnitude of the acceleration of one of the liners toward the other due to their mutual gravitational attraction? Treat the ships as par..
Conclude the electric field at the origin
Assume that the sun runs out of nuclear fuel & suddently collapses to form a white dwarf star, with a diameter equal to that of the Earth. Estimate the new rotation period of the Sun.
Classically, the electron cannot pass through the barrier because E
