Definition: Frequency is the measurement of the number of times that a repeated event occurs per unit of time. Sound moves through a medium such as air or water as waves. It is measured in terms of frequency and amplitude. Frequency, sometimes referred to as pitch, is the number of times per second that a sound pressure wave repeats itself.

A 9 v battery causes a current of 0.45 a through a resistor. (a) what is its resistance? (b) how many joules of energy does the
aliina [53]
\displaystyle I = \dfrac{u}{R} \Rightarrow R = \dfrac{u}{I} = \dfrac{9 \ V}{0.45 \ A}  = 20 \ \Omega. \newline
P = \dfrac{\Delta uq}{\Delta t} = Iu = 0.45 \ A \cdot 9 \ V = 4.05 \ \dfrac{J}{s} = 14580 \ \dfrac{J}{h} = 14.58 \ \dfrac{kJ}{h}.

What happens when sodium undergoes a chemical reaction with chlorine?
ozzi
They combine as atoms, and separate as ions. When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. The sodium (Na) atom transfers one electron to the chlorine (Cl) atom, so that they both have full outer shells. ... When this happens, the atom is called a positive ion.

xxTIMURxx [149]

Answer:

12.7m/s

Explanation:

Given parameters:

Mass of the diver = 77kg

Height  = 8.18m

Unknown:

Final velocity  = ?

Solution:

To solve this problem, we use one of the motion equations.

            v²  = u² + 2gh

v is the final velocity

u is the initial velocity

g is the acceleration due to gravity

h is the height

             v² = 0² + (2 x 9.8 x 8.18)

             v² = 160.3

             v = 12.7m/s
