Electrons in an X-ray tube accelerate through a potential difference of 104 Volt before striking a target. If an electron produces one photon on impact with the target, what is the minimum wavelength of the resulting X-rays?

Atransverse wave is traveling on a string stretched along the horizontal x-axis. the equation for the vertical displacement y of the string is given by y = (1.8 x 10-3)cos[π(13x - 60t)], where all quantities are in si units. what is the maximum speed of a particle of the string

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter
