A calculator is found to have a volume of 0.154 liters show using analysis what the volume of the calculator is in gallons?

0.1111 W/m²  is the sound intensity at a distance of 27 m from the generator.

The amount of energy travelling through a unit area in a unit of time perpendicular to the direction of the sound waves is known as the sound intensity. Sound intensity is inversely related to the square of the sound's distance when all other factors are held constant. This is,

I ∝ (1/r²)

I = k/r²

Since k can be the constant of proportionality. k = Ir²

We can write this relation as

I₁ × r₁² = I₂ × r₂²

I₁ = 0.25 W/m²

r₁ = 16 m

I₂ = ?

r₂ = 24 m

0.25 × 16² = I₂ × 24²

I₂ = (0.25 × 16²)/24²

I₂ = 0.1111 W/m²

The sample size of the standard deviation of a sample that was reported to be 30 is calculated as 8.

The process of deciding how many observations or replicates to include in a statistical sample is known as sample size determination.

Any empirical study with the aim of drawing conclusions about a population from a sample must take into account the sample size as a crucial component.

Standard deviation = square root of ∑(x-average)^2 / N = 30

∑(x-average)^2 = 7200

Putting the values in standard deviation formula where N = sample size

30 = sqrt of ∑(x-average)^2 / N

Then squaring off on both sides,

When there is an IR drop across a resistor, the current flowing through the resistor causes a change in potential or voltage across the resistor. based on Ohm's law

V = RI

where V is the resistance's voltage.

resistance, or R

I = present

R is now known to be constant.

The applied voltage also affects the current for a particular resistance.

Therefore, unless we change the resistance, no change in current is visible when current flows through a resistor.

When the IR drops across the resistor, the potential also drops using Ohm's law.

Thus, the potential energy of the electrons across the resistor drops. But the kinetic energy of the electrons remains the same.

The current is defined by the rate of flow of electrons which remains the same as the kinetic energy did not change.

Hence, the current won't change while passing through the resistor.

The empirical formula of the product gexcly is Ge4Cl.

a.) In empirical formula problem one must first find the mass % of the elements in the compound. Since the total mass of the final product was 3.69g we find that:

3.69g total-1.25g germanium = 2.44g chlorine

1.25g germanium/3.69 g total (100) = 33.88%

44g chlorine/3.69 g total (100) = 66.12%

b.) Then change the % to grams

33.88%→3.38g of Ge

72.23%→6.61g of Cl

c.) Next, divide all the masses by their respective molar masses.

3.38g /72.64gm-1 = 0.0465 moles Ge

6.61g/35.45gm-1 = 0.1864 moles Cl

d.) Pick the smallest answer of moles and divide all figures by that.

0.04 moles Ge / 0.0465 = 1

0.1864 moles Cl / 0.0465 = 4.00

Since our answer for chlorine is a whole number, we use them as coefficients for the product

The total photons at 660nm that are needed to be absorbed are 5.533 x 10²¹ in order to melt the ice.

Planck's equation is used to determine that the energy (E) of a photon is equal to hv = hc/λ, where this v is stated as the frequency of the electromagnetic radiation and λ as its wavelength.

Wavelength = 660nm = 6.60 x 10^-7 m

First, we find out the energy that is required to melt 5.0 x 10^2 grams of ice. This is given by:

Energy = mass multiplied by latent heat of fusion

Energy =   5.0 x 10^2g x 334 J/g

Energy = 167 x 10^3 J

So, we now have that to melt 5.0 x 10^2 g of ice, we need 334J of energy

Next, we can use Planck's equation which is:

Energy = (number of photons multiplied by Planck's constant x speed of light) / wavelength

167 x 10^3 J = [n * 6.64 x 10⁻³⁴ * 3 x 10⁸ ]/ 6.60 x 10^-7

By using uniform motion, the displacement of a fallen crate after 2.9 seconds is  41.209 meters.

We need to know about uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule

vt = vo + a . t

vt² = vo² + 2a . s

s = vo . t + 1/2 . a . t²

where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.

From the question above, we know that

t = 2.90 s

vo = 0 m/s

a = g = 9.8 m/s²

By substituting the given parameters, we can calculate the displacement with the third equation

s = vo . t + 1/2 . a . t²
