In order to effectively radiate a radio signal, an antenna must be at least one-half the wavelength of transmission in length, i. e., minimum antenna height = 1/2(λ). wity operates at a frequency of 980.0 khz. what is the minimum height (m) of the antenna that wity (nostalgia radio) must have? ,

Acar tire contains 0.0380 m^3 3 of air at a pressure of 2.20 ×10^{5} 5 n/m^2 2 (about 32 psi). how much more internal energy does this gas have than the same volume has at normal atmospheric pressure, 1.01x10^5 5 pa?

How are calculation for velocity and speed different

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
