The appropriate response is recycling aluminum products. Metal is a store in the Earths outside layer of at least one important minerals. The most profitable metal stores contain metals pivotal to industry and exchange, similar to copper, gold, and iron. Copper mineral is dug for an assortment of modern employments. Copper, an incredible conduit of power, is utilized as electrical wire.

Answer: recycling aluminium products

Ore is an aggregate of inorganic minerals, which are economically valuable. The ores are present in the rocks. The ores are extracted from earth through the process of mining. The minerals present in the ores are non-metals and metals.

Recycling of aluminium products is most useful for overcoming the disadvantage of using ores, because ores are non-renewable resources, which means that their abundance is low on earth and these resources once used cannot be replenish. Aluminium is a valuable metal extracted from ore, therefore, once used for a specific purpose as a product should be recycled in another form so that can be used again.

What is the period of a wave with a frequency of 100 Hz and a wavelength of 2.0 m
spin [16.1K]

The answer for the following answer is answered below.

  • <u><em>Therefore the time period of the wave is 0.01 seconds.</em></u>
  • <u><em>Therefore the option for the answer is "B".</em></u>

Explanation:

Frequency (f):

The number of  waves that pass a fixed place in a given amount of time.

The SI unit of frequency is Hertz (Hz)

Time period (T):

The time taken for one complete cycle of vibration to pass a given point.

The SI unit of time period is seconds (s)

Given:

frequency (f) = 100 Hz

wavelength (λ) = 2.0 m

To calculate:

Time period (T)

We know;

According to the formula;

<u>f =</u>\frac{1}{T}<u></u>

Where,

f represents the frequency

T represents the time period

from the formula;

  T = \frac{1}{f}

 T = \frac{1}{100}

  T = 0.01 seconds

<u><em>Therefore the time period of the wave is 0.01 seconds.</em></u>

Your spaceship lands on an unknown planet. To determine the characteristics of this planet, you drop a wrench from 5.00 m above
GenaCL600 [577]

Answer:

g = 15.5 m/s²

Explanation:

In order to find the acceleration due to gravity near the surface of this planet can be calculated by using 2nd equation of motion. The 2nd equation of motion is given as:

h = Vi t + (0.5)gt²

where,

h = height covered by the wrench = 5 m

Vi = Initial Velocity = 0 m/s

t = Time Taken to hit the ground = 0.804 s

g = acceleration due to gravity near the surface of the planet = ?

Therefore,

5 m = (0 m/s)(0.804 s) + (0.5)(g)(0.804 s)²

g = (5 m)/(0.3232 s²)

<u>g = 15.5 m/s²</u>
