Answer:

The correct answer is option D.

Explanation:

Wavelength of the wave = \lambda =35 m

Frequency of the wave = f = 4.0 Hz

Time taken by the wave = T

T=\frac{1}{frequency}=\frac{1}{4.0 Hz}=0.25 s

Speed of the wave:

Speed=\frac{35 m}{0.25 s}=140 m/s

Hence, the correct answer is option D.

Speed of a wave is the wavelength * frequency

speed = 35 * 4 = 140 m/s

HELP!!!
kondaur [170]

Answer: Geothermal resources are reservoirs of hot water that exist at varying temperatures and depths below the Earth's surface. Mile-or-more-deep wells can be drilled into underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications, including electricity generation, direct use, and heating and cooling. In the United States, most geothermal reservoirs are located in the western states.

Renewable—Through proper reservoir management, the rate of energy extraction can be balanced with a reservoir's natural heat recharge rate.

Baseload—Geothermal power plants produce electricity consistently, running 24 hours per day / 7 days per week, regardless of weather conditions.

Domestic—U.S. geothermal resources can be harnessed for power production without importing fuel.

How do properties move if in solid
Schach [20]

Answer:

In the solid phase, the forces of attraction have completely overcome molecular motion, and the movement of the particles has been reduced to vibrating in place. The particles cannot move past one another and are held in a tightly-packed pattern, so there is very little space between the particles.
