Define the ultrasonic welding applications.
Ultrasonic Welding Applications
Ultrasonic metal-welding is an advanced technical procedure for combining nonferrous metals, many metal-alloys and stranded wire. This is a cold-phase friction welding method; there is no melting, no high-temperature build up. This surfaces being connected are subjected to high frequency mechanical oscillations when being rubbed together in certain pressure. The molecules of the surfaces start to swirl and intermingle along with one other, creating a firm and lasting bond.
Enhancements in quality and efficiency, decreased energy needs and positive environmental factors are the decisive advantages of this latest technology.
Dual Nature of Light: As light is accepted as a form of waves as well as packets of photon. This nature of light is known as dual nature of light.
Distance of the earth from the moon and the sun is? The distance of the earth from the moon is 2,40,000 miles or24 x 104 miles and that from the sun is 93,000,000 or 93x106 mil

The velocity of a motor boat with respect to Still Water is 7 m/s and the velocity of water in river is 3 m/s. When the boat starts moving upstream, a float was dropped from it.
what is the effect of torque and equilibrium on taps, doors,handle bars and bicycles??
Is negative mass antimatter? No. There is really no such thing as negative mass. Even antimatter has mass, which is always a positive (that is, greater-than-zero) quantity.
In the figure below, the hand moves the end of the Slinky up and down through 2 complete cycles in 1 seconds. The wave moves along the Slinky at a speed of 0.60 m/s. Find the dista
why effective mass are tensor quantities
An infinite line of positive charge lies along the y axis, with charge density ? = 1.90 µC/m. A dipole is placed with its midpoint along the x axis at x = 22.00 cm. The dipole cons
The effects of back emf on circuit current: In proving the time constant, it was stated that, at the instant the switch is closed, the current (I) is zero. This is because, at
