Which example describes a nonrenewable resource?

Physics
2 answers:
BARSIC [14]4 years ago
7 0

Answer:

Refineries process oil, found in the Earth, and turn it into gasoline to be used by cars.

Explanation:

The first option describes Geothermal energy. Geothermal energy uses the heat of the Earth's crust as a heat source. It is a renewable resource.

Refineries use the oil extracted from the Earth to produce gasoline. This is a non renewable resource as the oil found in the Earth is of finite quantity and is being depleted faster than it is being replenished.

Solar panels use the sunlight to produce electricity. Sunlight is a renewable resource.

Windmill uses the power of moving air to generate electricity. Wind is a renewable resource.

Nana76 [90]

The formula used in calculations relating to transformers is:

<span>Secondary voltage (Vs)/ Primary voItage (VP) = Secondary turns (nS)/ Primary turns (nP)</span>

 

Substituting the given values to find for Vs,

Vs / 120 V = 400 turns / 100 turns

<span>Vs = 480 V</span>

He measures 100ml of hot water (90 degrees) using a graduated cylinder he places this sample in the refrigerator to cool it down
Rasek [7]

The volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.

<h3>Why does water change in volume?</h3>

Water is a substance that is known for its unique characteristics that makes it stand out among all other liquids.

One notable feature of water is it's ability to become denser when subjected to cooler temperatures i.e. water is more dense when cold.

As water cools or becomes less warm, it contracts and decreases in volume. When water decreases in volume, it becomes more dense.

Therefore, according to this question, it can be said that the volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.

What is the difference in electrical potential energy between two places in an electric field?
Phoenix [80]

Answer: Option (c) is the correct answer.

Explanation:

The difference in electrical potential energy between two places in an electric field is known as potential difference.

Mathematically, potential difference between two given points can be written as follows.

             \Delta V = V_{2} - V_{1}

where,    \Delta V = potential difference

              V_{1} = potential at point 1

               V_{1} = potential at point 2

What is the force of gravitational attraction between an object with a mass of 2kg and another object that has a mass of 2kg and
kupik [55]

Answer:

1.7x10^-10 N

Explanation:

F = G [(m_1)(m_2)]/(r^2)

F = force

G = Gravitational constant 6.67433x10^-11 (N*m^2)/kg^2

m_1 = mass first object

m_2 = mass second object

r = radius between the 2 objects

F = G[(2 kg*2 kg)/(1.25 m)^2]

F = 1.7x10^-10 N

A horizontal force of 150 N is used to push a 40.0-kg packing crate a distance of 6.00 m on a rough horizontal surface. If the c
icang [17]

Answer:

a. 900 J

b. 0.383

Explanation:

According to the question, the given data is as follows

Horizontal force = 150 N

Packing crate = 40.0 kg

Distance = 6.00 m

Based on the above information

a. The work done by the 150-N force is

W = F x = \mu N x = \mu\ m\ g\ x

W = 150 \times 6

= 900 J

b. Now the coefficient of kinetic friction between the crate and surface is

\mu = \frac {F}{m\timesg}

= \frac{150}{40\times 9.8}

= .383

We simply applied the above formulas so that each one part could calculate
