Answer:
B) The frequency will increase
Explanation:
The length of the instrument is given by
Wavelength is given by
It can be seen that the length is inversely proportional to the frequency.
Here, the length of the trombone is decreasing so the frequency will increase.
False. You have columns that are groups and rows that are periods.
Answer: The total energy created by the Alpha decay.
Explanation: The sum total of the kinetic energy of the alpha particle and the new nucleus is the total energy created by the alpha decay.
Consider the decay of a radioactive nuclide by the spontaneous emission from its nuclei of alpha particles. An alpha particle which is composed of two protons and two neutrons and has a charge of +2. With an appreciable mass and its ejection from the nuclide creates a certain amount of recoil energy in the nucleus. The total energy (Ex) created by alpha decay is therefore the sum of the kinetic energy of the particle, the recoil energy given to the new nucleus, and the total energy of any emitted gamma rays.
Out of all of the following, Iron is a metal.
So the correct answer is B.

Rate of change of velocity is called acceleration. When this rate of change is constant, it is called uniform acceleration. Like the change of velocity of an object falling freely under gravity. Its velocity increases by 9.8 m every second. This acceleration is denoted as 9.8m/s^2
