In your hand, the ball has higher potential energy than kinetic because it is still off of the ground but it isn't moving so there is no kinetic. As the ball rises, its potential and kinetic energy increases. At its peak, it has very high potential energy and very low kinetic energy. As it falls, the potential energy decreases but kinetic does not.
State the order in which the ions associated with a compound composed of potassium and bromine would be written in the chemical formula and the compound name.
Answer:
Atom - un átomo de hidrógeno pierde un electrón, adquiere una carga positiva
Molecule - Al aumentar el calor, las moléculas se alejan en mayor medida unas de otras y se intensifica su estado de agitación.
Answer:
B
Explanation:
To calculate questions like this, you need to make use of the equation below:
ν = c / λ
ν is the frequency, c is the speed of light, and λ is the wavelength
ν = c / λ
2.45 • 10^9 Hz = (3•10^8 m/s)/(λ)
λ = 0.122 m = B
