Answer:

Nonrenewable energy

Explanation:

Renewable energy is also known as clean energy and it can be defined as a type of energy that are generated through natural sources or technology-based processes that are replenished constantly. Some examples of these natural sources are water (hydropower), wind (wind energy), sun (solar power), geothermal, biomass, waves etc.

Basically, a renewable energy source is sustainable and as such can not be exhausted.

On the other hand, a non-renewable energy refers to an energy source such as fossil fuels that takes a very long time to be created or their creation happened long ago and isn't likely to happen again e.g uranium.

For example, fossil fuels such as coal, oil, and natural gas, come from deep inside the Earth where they formed over millions of years ago.

In this scenario, the kind of energy the newspaper sources are talking about is a nonrenewable energy source because they are capable of being exhausted in the not-so-distant future.

What is the height of a 2.00 kg object if its potential energy is 100 J?
lara31 [8.8K]

<u>Given that:</u>

       height (h) = ?

       mass  (m) = 2 Kg ,

       Potential energy (P.E.) = 100 J ;

    We know that P.E = m × g × h

                            100 J = 2 × 9.81 × h

                                h = (100) ÷ (2 × 9.81)

                              <em>  h  = 5.09 m</em>

25th November 1936 - Germany and Japan signed a treaty against communism - Anti-Comintern Pact

22nd May 1939 - Germany and Italy signed a stronger alliance - Pact of Steel
27th September 1940 - Japan signed the Pact of Steel - It became known as the Tripartite Pact.

What is the empirical formula of a compound that contains 27.0% s
eduard

Answer:

Empirical formula of the compound = SOCl₂

Explanation:

QUESTION:What is the empirical formula of a compound that contains 27.0% S, 13.4% O, and 59.6% Cl by mass?

The empirical formula of a compound is its simplest formula. It tells us

* The component element present in a molecule of the compound.

* The ratio  in which these elements are combined together, i.e mole ratio.

To calculate the empirical formula of a compound that contains 27.0% S, 13.4% O, and 59.6% Cl by mass. ( Relative atomic mass of S=32gmol⁻¹, 0=16gmol⁻¹, Cl=35.5gmol⁻¹)

                                           Sulphure S,  Oxygen O, Chlorine Cl

percentage by mass:            27.0%                  13.4%            59.6%

Step 1:

Divide by their relative

atomic mass:                     27.0/32.0      13.4/16.0         59.6/35.5    

⇒⇒⇒⇒⇒⇒⇒⇒⇒                  0.844            0.838            1.679

Step 2:

Divide by the

smallest mole ratio:       0.844/0.838   0.838/0.838  1.679/0.838

∴                                            1              :         1           :       2.

from the analysis above, the compound contains Sulphur, Oxygen and Chlorine in the ratio of 1:1:2.

∴ Empirical formula of the compound = SOCl₂

What total distance will a sound wave travel in air in 3.00 seconds at stp?
dimaraw [331]
At stp conditions (T=0^{\circ}C), the speed of sound is
v=331.2 m/s
The sound wave moves by uniform motion, so we can use the basic relationship between space, time and velocity:
S=vt
where S is the distance covered by the sound wave in a time t. In our problem, t=3.00 s, therefore the distance covered by the sound wave is
S=vt=(331.2 m/s)(3.00 s)=993.6 m
