Two Particles A and B are moving towards each other. Particle A has mass of 50.0kg moving from the left side at 9m/s. Particle B has mass of 70.0 kg moving at 7m/s from the right. Inelastic collision takes place. Explain their motion quantitative after their impact.
Your friend has a pair of fuzzy dice with a mass of 1.24 gram hanging from his rear-view mirror. Find at what angle to the vertical will the tension in the string be twice the weight of the dice
the relativity twins simplicio and salviati are taking separate spaceships to another planet which we have measured to
Two speakers, one directly behind the other, are each generating a 374-Hz sound wave. What is the smallest parting distance between the speakers that will generate destructive interference at a listener standing in front of them? Take the speed of so..
A charged 2uF capacitor is connected in parallel with 0.5 MOhm resistor. a) How long after the connection is made with the voltage across the capacitor to 75% of its maximum value. b) How much thermal energy will be dissipated across the resistance a..
A weightlifter has been given a barbell to lift. One end has a mass of 5.05 kg while the other end has a mass of 5.20 kg. The bar is 0.20 m long. (Consider the bar to be massless, and assume that the masses are thin disks, so that their centers of ma..
Assess the benefits brought about by the application of lean techniques at Wiremold. Explain your answer by describing the changes and their outcomes.
A 1 115.0 kg car traveling initially with a speed of 25.000 m/s in an easterly direction crashes into the back of a 8 200.0 kg truck moving in the same direction at 20.000 m/s. What is the velocity of the truck right after the collision
two blocks are pressed together, compressing a spring, the system is then released from rest on a level, frictionless surface. the spring is not attacthed to either block and drops to the surface after it is expanded. i need to demonstrate whether th..
How many electrons should be removed from an initially uncharged spherical conductor of radius 0.29 m to produce a potential of 6.8 kV at the surface
A 1 kg block attached to a spring with force constant 25 N/m oscillates on a horizontal, frictionless air track. At t = 0, the block is released from rest at x = ?3 cm. (At that time the spring is compressed by 3 cm).
An engineer wishes to determine the spring constant of a helical spring. She first puts enough weights on the spring to pull the coils apart. What is the best estimate of the spring constant
When a signal of intensity 3.0kWm-2 is applied at the input of an amplifier of length 10m, the output signal intensity is 36kWm-2. When the input intensity is reduced to 1.0kWm-2 the output is 20kWm-2.
