Q1. An airplane is flying with a velocity of 92.0 m/s at an angle of 23.0^circ above the horizontal. When the plane is a distance 111 m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
Q2. Consider two small magnets (treat them as point like perfect dipoles with magnetic moments m1 and m2, to keep life as simple as possible). For the configuration shown ("opposite poles facing"), illustrate a diagram showing the relative orientation of the magnetic dipoles m1 and m2 of the two magnets. Then find the force between them as a function of distance h. describe why the sign of the force does (or does not) make sense to you.
How much time is necessary for the torso to come to rest
A doubly charged helium atom whose mass is 6.6 10 to 27 kg is accelerated by a voltage of 2200 V. What will be its radius of curvature if it moves in the plane perpendicular to a uniform 0.308 T field?
A tank with a volume of 0.150 m contains 27.0 degrees celcius helium gas at a pressure of 100 atm. How various balloons can be blown up if each filled balloon so a sphere 30.0 cm in diameter at 27.0 and absolute pressure of 1.20atm .
Establish an average acceleration
A steel wire of length 1.97 with circular cross section must stretch no more than 0.260 when a tensile (stretching) force of 400 is applied to each end of the wire. What is the minimum diameter necessary.
Driving in your car with a constant speed of 13 m/s, you encounter a bump in the road that has a circular cross section, as indicated in the figure. If the radius of curvature of the bump is r = 29 m, find the apparent weight of a 59-kg person in you..
What is the angular velocity in rad/s . What is the least pressure obtained inside the bottle? What will happen when this pressure is reached.
The change in the kinetic energy of the system
A particle oscillates with S.H.M. The maximum displacement from its mean position is 0.5 meter and frequency of motion is 10 Hz. at time t=0, particle is located at 0.15 meter and has the velocity of 24.0 m/s towards the negative x-axis.
What is current temperature and peak wavelength What is the proper description of their situation
If the velocity of the car is increased to 50 km/ hour, what is its kinetic energy. if the velocity is improved to 75 km/ hour, what is its kinetic energy.
