Answer:

1.54 × 10⁻¹⁰ m

Explanation:

A number in scientific notation has the form A × 10ⁿ.

A is a number from 1 to 10, but not 10 itself and is called the <em>coefficient</em>.

n is an integer and is called the <em>exponent</em>.

To convert a small decimal number to exponential notation, you move the decimal point to the right until you have one nonzero digit in front of the decimal point.

The exponent is negative of the number of places you moved the decimal point.  

To convert 0.000 000 000 154 m to scientific notation:

  • Move the decimal point to the right until it is just past the 1. The coefficient is 1.54
  • Count the number of places you have moved the decimal (ten). The exponent is -10.

The number in scientific notation is 1.50 × 10⁻¹⁰.

Add the units and the <em>measurement</em> is 1.50 × 10⁻¹⁰ m.

Phantasy [73]

Answer:

A chemical change

Explanation:

The marshmallow turning brown and bubbling implies that a chemical change has taken place.

For chemical changes to occur, we observe any of the following:

  • a new kind of matter is formed.
  • it is always accompanied by energy changes
  • the process is not easily reversible
  • it involves a change in mass
  • requires considerable amount of energy.

ii. Two signs that shows a chemical change has taken place is that:

  • bubbles are being formed as it is roasted and it implies that new substances have been formed.
  • also, significant amount of heat energy is supplied for the roasting.

Greenhouse gases released from the burning of fossil fuels are responsible for global warming.

<h3>What is the atmosphere?</h3>

The atmosphere is the region of region of the planet above its surface area where gases envelop the planet.

Based on the effect of greenhouse gases on global warming;

  • Planet A has a higher surface temperature due to the higher amount of carbon dioxide in the atmosphere since carbon dioxide is a greenhouse gas.
  • Methane is the main constituent of natural gas. Humans increase the contribute to increase in methane gas by raising cattle,
  • Pollutants come from both natural sources and human activities.
  • Sulfur Dioxide is produced by the combustion of fuels in automobiles. Once in the atmosphere, it combine with water to form acid precipitation.
  • Nitrogen and oxygen do not contribute to the greenhouse effect because they are  made up of 2 atom molecules that are bound tightly so they CANNOT vibrate to absorb energy.
  • Greenhouse gases contribute to global warming by absorbing infrared energy that reflects off Earth's surface and reemitting the energy in all directions. This keeps the infrared energy close to the Earth's surface.
  • Most of the greenhouse gases produced come from burning fossil fuels in factories, ships, cars, trains.

Therefore, pollutants such as greenhouse gases are responsible for global warming.

By mistake, a quart of oil was dumped into a swimming pool that measures 25.0 m by 30.0 m. The density of the oil was 0.750 g/cm
kondor19780726 [428]

The oil slick thick = 1.256 x 10⁻⁴ cm

<h3>Further explanation</h3>

Volume is a derivative quantity derived from the length of the principal

The unit of volume can be expressed in liters or milliliters or cubic meters

The conversion is

1 cc = 1 cm3

1 dm = 1 Liter

1 L = 1.06 quart

<em>so for 1 quart = 0.943 L</em>

\tt 0.943~L=0.943\times 10^{-3}m^3

Volume of oil dumped = volume of swimming pool

\tt 0.943\times 10^{-3}~m^3=25\times 30\times h(h=thick)\\\\h=\dfrac{0.943\times 10^{-3}}{750~m^2}=1.257\times 10^{-6}~m=\boxed{\bold{1.256\times 10^{-4}~cm}}
