Two long parallel wires carry currents of 3.31 A and 6.17 A. The magnitude of the force per unit length acting on each wire is 3.93 × 10-5 N/m. Discover the separation distance of the wires expressed in millimetres.
The pressure fluctuation of sound waves at the closed end of a pipe vibrating at resonance is: 1. Minimum 2. 1/2 minimum 3. unchanged 4. maximum 5. 1/2 maximum
A 55-kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.30. What is the frictional force on the box
a 45kg box is pulled across a horizontal floor. a rope attached to the box makes an angle of 30 degrees with the
Anya and Ilya each can run at a speed of 7.20 miles per hour and walk at a speed of 4 mph. They set off together on a route of length 5 miles. Determine how long does it take Ilya to cover the distance
A physics lecture room has a volume of 251m^3. Calculate the mass of the air in the room
A spool whose inner core has a radius of 1.00 cm and whose end caps have a radius of 1.50 cm has a string tightly wind around the inner core. The spool is free to roll without slipping on a horizontal surface.
Converting sunlight to electricity with solar cells has an efficiency of 15%. It's possible to achieve a higher efficiency (though currently at higher cost) by using concentrated sunlight as the hot reservoir of a heat engine. What is the theoreti..
Balance the meter stick at its center of gravity and hang an unknown mass (e.g. your keys) at the 90 cm mark. Place the 200-g mass on the meter stick at a location until equilibrium is reached. Record this position. what is the advantage of having th..
Transverse waves on a string have wave speed v=8m/s , amplitude A=0.0700 m , and wavelength lambda= 0.320 m . The waves travel in the -x direction, and at t = 0 the x = 0 end of the string has its maximum upward displacement.
Calculate the angular velocity? of an electron orbiting a proton in the hydrogen atom, given the radius of the orbit is 0.500x10-10 m . You may assume that the proton is stationary and the centripetal force is supplied by Coulomb attraction.
When are the displacement, velocity, and acceleration equal to zero for the motion of a mass on a spring? A. at maximum displacement B. at minimum displacement C. at the equilibrium position D. at a displacement of 2x E.at a displacement of 1/3x.
The collision between a hammer and a nail can be considered to be approximately elastic. Estimate the kinetic energy acquired by a 14-g nail when it is struck by a 550-g hammer moving with an initial speed of 3.3 m/s.
