Which of the following would be considered a source of geothermal energy?

N76 [4]

Answer:

Explanation:

Magma heats nearby rocks and underground aquifers. Hot water can be released through geysers, hot springs, steam vents, underwater hydrothermal vents, and mud pots. These are all sources of geothermal energy. Their heat can be captured and used directly for heat, or their steam can be used to generate electricity.

What is the wavelength of a radiowave that has a frequency of 9.650 x10^7 Hz (cycles per second)?h = 6.6261 x10^-34 J/sc = 2.998

slava [35]

Hello!!

For this, we only need frequency and speed, so for calculate we applicate formula:

$\boxed{\lambda = V/f}$

$\textbf{Being:}$

$\sqrt{}$ $\lambda = Wavelength = \ ?$

$\sqrt{}$ $V = Velocity = 2.998*10^{8} \ m/s$

$\sqrt{}$ $f = Frequency = 9,650*10^{7} \ Hz$

$\text{Then let's \textbf{replace it according} we information:}$

$\lambda = 2,998*10^{8} \ m /s / 9,650*10^{7} \ Hz$

$\lambda = 3.106 \ m$

$\textbf{Result:}\\\text{The wavelength of the radiowave is \textbf{3.106 meters}}$

How the energy affects the speed of the particles in a substance

Daniel [21]

Increases

Explanation:

Energy increases the speed of the particles in a substance. When energy is added to a substance they gain more kinetic to move.

When energy is added to solid, the particles begins to vibrate about their fixed point.
They reach a point where they break lose and the ordered structure of a typical solid collapses.
They begin to move about freely and flow as in a liquid.
When enough energy is added, they break their intermolecular attractions and becomes gaseous.
An increase in energy increases the kinetic energy of the particles of a substance.
The reverse is the case when energy is removed.
