Answer:
The movement of electrons in the presence of a magnetic field.
Explanation:
cathode-ray tube (CRT) has to do with
a vacuum tube in which an electron beam is deflected by applying electric or magnetic fields, produces a trace on a fluorescent screen. Cathode-ray tubes are uses in the television (TV) display. Other uses include radar displays, oscillography, and visual displays for computer terminals.
Density(rho) = m/v
(1.3)/((3.2)(17.1)(3.8))
since density is given in kg/m^3 you should convert the blocks dimensions to meters
1.3/(0.032*0.038*0.171)
plugging in these numbers would give you the density
1.3/0.000208
6250
with sigfigs= 6300kg/m^3
