Answer:

False

Explanation:

Science is not based on primarily on peoples opinions and views of the subject matter whereas science is based on empirical observations and research for its validity.

<u>Science aims to find answers to human questions related to the natural world through their research observation and experiments. Scientists and researchers provide valid proof of human questions so that people can trust them.</u>

Science can change people's opinions regarding the natural world with valid proof and observational theories but science is not based on people's opinion.

Hence, the given statement is "false".

Why is there a delay for the tides to react to the Moon's and Sun's gravitational effect?

Sloan [31]

There is no delay because the effects of gravity are constantly acting on bodies of water. Hence, option D is correct.

<h3>What is the gravitational effect?</h3>

Gravitation or just gravity is the force of attraction between any two bodies.

The Moon exerts over twice the gravitational pull of the Sun on Earth's tides because of its proximity to Earth. -The lunar tidal bulges are about twice the size of the solar tidal bulges. -The Sun's contribution to the tides is less than that of the Moon.

When the sun and moon are perfectly unaligned (they form a 90-degree angle relative to the earth), there are still tides because the moon's gravitational gradient is stronger than the sun's. The sun's gravitational gradient never completely cancels out the moon's.

Hence, option D is correct.

A weight of 100 pounds moved a distance of 12 feet equals 120 240 1200 ft.-lbs. of work.

Archy [21]

Work = Fdcos(alpha)

Where F is force, D is distance, and Alpha is the angle to the parallel plane (in this case the ground)

I’ll assume alpha is 0 since it’s not given

100 • 12 • cos(0) = 1200 ft-lbs

100 points!! Brainliest if correct!!

Misha Larkins [42]

D has the fastest reaction rate because dynamite explodes almost immediately.

A isn't correct because rusting nails take forever to completely rust.

B isn't correct because logs burning can take around 10 to 20 minutes.

C isn't correct because food digestions takes anywhere between 10 minutes to an hour.

Natural gas (CH4) has a molar mass of 16.0 g/mole. You started out the day with a tank containing 200.0 g of natural gas. At the

hodyreva [135]

Considering the definition of molar mass, the moles of gas used are 10.625 moles.

<h3>Definition of molar mass</h3>

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

<h3>Amount of moles used</h3>

Natural gas has a molar mass of 16.0 g/mole.

You started out the day with a tank containing 200.0 g of natural gas. So, you can apply the following rule of three: If by definition of molar mass 16 grams are contained in 1 mole, 200 grams are contained in how many moles?

$amount of moles at the beginning=\frac{200 gramsx1 mole}{16 grams}$

<u><em>amount of moles at the beginning= 12.5 moles</em></u>

At the end of the day, your tank contains 30.0 g of natural gas. So, you can apply the following rule of three: If by definition of molar mass 16 grams are contained in 1 mole, 30 grams are contained in how many moles?

$amount of moles at the end=\frac{30 gramsx1 mole}{16 grams}$
