A pulse with a height of +0.5 meters encounters a second pulse with a height of +2.3 meters. A. The 2 pulses interfere:

B. The resulting height of the medium when the pulses interfere will be: m

A pulse with an amplitude of 0.4 meter moves from thick, heavy cord where its speed is 2.0 meters per second into a much thinner string. the speed and height of the pulse after it is transmitted could be:

1. Amplitude = 0.5 m; Speed = 1.0 m/s
2. Amplitude = 0.3 m; Speed = 1.0 m/s
3. Amplitude = 0.5 m; Speed = 3.0 m/s
4. Amplitude = 0.3 m; Speed = 3.0 m/s

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
