A light plane is headed due south with a speed of 190km/h relative to still air. After 1.00 hour, the pilot notices that they have covered only 137km and their direction is not south but 15.0? east of south.
A) What is the wind velocity (magnitude)?
B) What is the wind velocity (direction)?
What is the maximum rate of rotation. A moving electron passes near the nucleus of a gold atom, which contains 79 protons and 118 neutrons. At a particular moment electron is a distance of 7.5 x10 ^9 m from the gold nucleus.
What is direction of the resultant velocity
The mass of a robot is 5220 kg. This robot weighs 2650 N more on planet A than it does on planet B. Both planets have the same radius of 2.26 × 107 m
A roof-top solar water heater collects 50% of the 200 W/m^2 provided by the sun, using absorbers with a total area of 30m^2. If water enters the system at 15(C), how many hours will be required to warm 150kg of water to 60(C) using this heater? (Y..
A point charge q1=4nC is placed at the origin, and a second point charge q2= -3nC is placed on the x-axis at x= 20 cm. A third point charge q3=2.00 nC is to be placed on the x-axis between q1 and q2.
A parallel-plate air capacitor with a capacitance of 245 has the charge of magnitude 0.1502 on each plate. The plates have the separation of 0.323.
A pilot flies an airplane at a constant speed of 520 km/hr in the vertical circle of radius 1400 m. compute the force exerted by the seat on the 105-kg pilot at point A and at point B.
In one such decay, the electron and the neutrino are emitted at right angles to each other. The electron(mass 9.11 x 10^-31kg) has a speed of 5.00×10^7m/s and the neutrino has a momentum of 8.10×10^-24kg m/s. What is the recoil speed of the nucleu..
