Which explanation is based on empirical evidence? Ancient text reveals that the universe is about 6000 years old

Physics

Answer:

Empirical evidence is evidence that is verified by observation or experience, rather than logic or theory.

Then an explanation is based in on empirical evidence is an explanation that uses a fact that was seen or experienced.

The case here:

"Ancient text reveals that the universe is about 6000 years old"

Is not empirical, because there is no observation or experience here, this is only a book that says the opinion of who wrote it.

An example of an empirical explanation would be:

"The universe is at least X years old because we can see remanents that are X years old"

The advertising method that this demonstrates is card stacking.

An advertising method in which the buyers are persuaded to buy a product by deliberately disguising information and trying to distort actual details by suppressing the holistic information on the product.

In this case, the company is focusing on the positive side of the product thereby deliberately excluding other important details about harm caused by the product.

This is a case of card stacking.

Two 2.5 kg bowling balls are 0.50 m apart. What is the force of gravity of the first bowling ball due to the
Makovka662 [10]

Answer:The answer is A

Explanation:

To determine the force, we use the equation

Fg= G m1 m2/r2

, where Fg is the force of gravity, G is the gravitational constant,

m1

is the mass of the first body,

m2

is the mass of the second body, and r is the radius. Hence, we have

Fg=6.67×10−11 N×m2/kg2×2.5 kg×2.5 kg/(0.50 m)2=1.7×10−9N

. Since this is a gravitational problem, the force on one body has the same force as the other body, but the directions are opposite.

2 Resistors of resistance, R = (100 +- 3) Ohm, R2 = (200+-4)Ohm are connected in Parallel and Series.
Orlov [11]

According to what I've learnt, in any expression of multiplication or division, the percentage errors of each term are added up to find the equivalent percentage error. That is, if

<span><span>y=<span>ABC
</span></span><span>
y=<span>ABC</span></span></span>then<span><span>% error in y= % error in A + % error in B + % error in C</span></span>

For the above problem, let <span><span>Rs</span></span> denote series combination. Then <span><span><span>Rs</span>=300±7</span></span> ohm.

Let <span><span>Rp</span></span> denote parallel combination.

<span><span>∴<span>Rp</span>=<span><span><span>R1</span><span>R2/</span></span><span><span>R1</span>+<span>R2 </span></span></span>= <span><span><span>R1</span><span>R2/</span></span><span>Rs</span></span></span></span>

Ignoring errors, we get <span><span><span>Rp</span>=<span>200/3 = </span></span></span><span><span>66.67</span></span> ohm

<span><span>%<span>error in R1</span>=3</span></span>, <span><span>%<span>error in R2</span>=2</span></span>, <span><span>%<span>error in Rs</span>=<span>7/3</span></span></span>

Hence, <span><span>%<span>error in Rp</span>=3+2+<span>7/3</span>=<span>22/3</span></span></span>

So, error in <span><span>Rp</span></span> will be <span><span><span>22/3</span>% of </span></span><span><span>200/3</span></span>, which is approximately <span>4.89.</span>

Hence, I got <span><span><span>Rp</span>=66.67±4.89</span></span> ohm.

However, the book used the formula described and proved here and arrived at the answer <span><span><span>Rp</span>=66.67±1.8</span></span>ohm.

geniusboy [140]

Answer:

Explanation:

First, he can add the rock salt to the water and mix it well. Then he can remove the sand by decantation, after the sand has sedimented. He can seperate the water from the salt by evaporation. He should evaporate the water completely and capture the steam. the steam will cool into water. After evaporating completely, the salt will remain in the container
