The chemical and physical actions of groundwater form Karst topography. It is <span>any region where the terrain has been dissolved by the physical and chemical weathering of the bedrock.
There is no reason why glaciers, volcanoes, and mountains should be formed as a result of these actions. </span>

A spring is compressed 8 cm. It is then brought back to equilibrium and compressed 24 cm. How much more work is done in the seco

posledela

Answer:

Nine times

Explanation:

$x_{i}$ = Initial compression of the spring = 8 cm = 0.08 m

$x_{f}$ = Final compression of the spring = 24 cm = 0.24 m

$k$ = Spring constant of the spring

Initial spring energy is given as

$U_{i} = (0.5) k x_{i}^{2}\\U_{i} = (0.5) k (8)^{2}\\U_{i} = 32 k$

Initial spring energy is given as

$U_{f} = (0.5) k x_{f}^{2}\\U_{f} = (0.5) k (24)^{2}\\U_{f} = 288 k = (9) (32) k = 9 U_{i}$

List the main types of electromagnetic waves in order of increasing frequency. radio waves, microwaves, infrared, visible light,

alexandr1967 [171]

Answer:

radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays, gamma rays

Explanation:

Electromagnetic waves are oscillations of electric and magnetic fields in a direction perpendicular to the direction of motion of the wave (transverse waves). They are classified into 7 different types, according to their frequencies.

From lowest to highest frequency, we have:

Radio waves

Microwaves $10^9 Hz - 4\cdot 10^{13}Hz$

Infrared $4\cdot 10^{13} - 4\cdot 10^{14} Hz$

Visible light $4\cdot 10^{14} - 8\cdot 10^{14}Hz$

Ultraviolet $8\cdot 10^{14} - 2.4\cdot 10^{16} Hz$

X-rays $2.4\cdot 10^{16} -5 \cdot 10^{19}Hz$

Gamma rays $>5\cdot 10^{19} Hz$
