Describe what happens to the proton number and the mass number when an alpha particle is emitted by a nucleus?
When an alpha particle (helium nucleus) is emitted by a nucleus, the proton number decreases by 2 and the mass number decreases by 4. This is because the alpha particle consists of two protons and two neutrons.
What happens to the average kinetic energy of the particles the pressure and number of collisions when the temperature is decreased?
When the temperature is decreased, the average kinetic energy of particles decreases since temperature is directly related to the average kinetic energy of particles. As a result, the pressure and number of collisions between particles will also decrease because particles will have less energy to move and collide with each other.
What number of wavelengths passing through a given point per second?
The number of wavelengths passing through a given point per second is determined by the frequency of the wave passing through that point. It is calculated using the formula: number of wavelengths = frequency of the wave.
What happens to interference pattern if wavelength of light is decreased?
the light must be coherent - which happens when a single beam of light is split
What is the number of electrons flowing through the wire?
The number of electrons flowing through a wire depends on the current passing through it. One ampere of current corresponds to approximately 6.24 x 10^18 electrons flowing through the wire per second.
