A large bottle contains a number of medicinal tablets each having a mass of 250mg. The mass of all the tablets is 1 kg. Calculate the number of tablets in the bottle.

Answers

Considering the rule of three, the number of tablets in the bottle is 4.

In first place, the rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied.

To solve a direct rule of three, the following formula must be followed, being a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: $x=(cxb)/(a)$

The direct rule of three is the rule applied in this case as follow: if 250 mg = 0.250 g is the mass of 1 medicinal tablet, 1 kg = 1000 g is the mass of how many medicinal tablets?

0.250 grams ⇒ 1 medicinal tablet

1000 grams ⇒ x

Then:

$x=(1000 gramsx1 medicinal tablet)/(0.250 grams)$

x= 4 medicinal tablets

Finally, the number of tablets in the bottle is 4.

Given parameters:

Mass of each tablet = 250mg = 0.25g

Mass of all tablets in the bottle = 1kg = 1000g

Unknown:

Number tablets in the bottle = ?

Solution:

The number of tablets in the bottle;

Number of tablets = $(mass of all tablets in the bottle)/(mass of each tablet)$

Mass is the amount of matter that makes up a substance

Number of tablets = $(1000g)/( 250 x 10^(-3) )$ = 4000 tablets

An angular frequency wave ω0 has an average power P0. If your angular frequency increases by 20%, find the percentage by which its power increases.

Answers

Answer:

44%

Explanation:

The average power of a wave is directly proportional to the square of the frequency.

P ∝ ω²

Writing a proportion:

P₁ / P₀ = ω₁² / ω₀²

P₁ / P₀ = (1.2 ω₀)² / ω₀²

P₁ / P₀ = 1.44

P₁ = 1.44 P₀

The power increases by 44%.

Which list places the layers of the sun in the correct order from innermost to outermost?Corona, photosphere, chromosphere
Photosphere, convective zone, radiative zone
Convective zone, chromosphere, corona
Radiative zone, corona, convective zone

Answers

The Photosphere, Chromosphere, Transition Region, and Corona are the outer layers. Option A is correct.

What are the layer of sun?

Corona, photosphere, chromosphere are the layers of the sun in the correct order from innermost to outermost.

The distance is measured from the sun's core for the inner layers and from the sun's surface for the outer layers. The Core and Convection Zone, are the inner layers.

The Photosphere, Chromosphere, Transition Region, and Corona are the outer layers.

Hence, option A is correct.

Compare the outermost electrons of an atom with the inner most electrons of an atom in terms of energy

Answers

The innermost electron of an atom has the lowest level of energy while the outermost electron has the highest level of energy.
There are different energy levels in the atoms of elements, for an atom to go into an higher level it has to obtain more energy and to go to lower level it has to lose energy.

The acceleration due to gravity on the moon is about one-sixth its value on earth. If a baseball reaches a height of 67 m when wurth (jaw6696) – Ch 2 LT 3/4 – kreft – (61920) 2 thrown upward by someone on the earth, what height would it reach when thrown in the same way on the surface of the moon? Answer in units of m.

Answers

Answer:

402m

Explanation:

We can solve this easily by using the free fall formula:

$v_f^2=v_0^2+2ad$

On both cases the final velocity will be 0m/s (maximum height), so we have:

$v_0^2=-2ad$

We know that the velocity the person imparts to the ball will be the same either on Earth or on the Moon, so we write for both cases:

$v_0^2=-2a_Ed_E$

$v_0^2=-2a_Md_M$

Which means

$2a_Ed_E=2a_Md_M$

So we get (taking into account that gravity on earth is 6 times gravity on the Moon):

$d_M=(a_Ed_E)/(a_M)=(6a_Md_E)/(a_M)=6d_E=6(67m)=402m$

You dip your finger into a pan of water twice each second, producing waves with crests that are separated by 0.15 m. Determine the frequency, period, and speed of these water waves.

Answers

Frequency = rate of sploosh = 2 per second = 2 Hz.

Period = ( 1/frequency ) = 1/2 second

Speed = (wavelength) x (frequency) = (0.15m) x ( 2/sec) = 0.075 m/s .
