Answer:

I = 1.36 x 10⁻⁴ W/m²

Explanation:

The intensity of the sound produced by the Elephant can be calculated by using the following formula:

[tex]I = \frac{P}{A} \\\\[/tex]

where,

I = Intensity of sound = ?

P = power of sound = 0.45 W

A = area = πr² = π(32.5 m)² = 3318.3 m²

Therefore,

[tex]I = \frac{0.45\ W}{3318.3\ m^2} \\\\[/tex]

I = 1.36 x 10⁻⁴ W/m²

What process is represented by this redox equation ?

6H 2 O+6CO 2 C 6 H 12 O 6 +6O 2

This equation is of the process of photosynthesis. The proper equation is :-

6CO2+6H2O→C6H12O6+6O2.

Answer:

ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.

Explanation:

Materials when heated emit a continuous spectrum with all wavelengths.

Hot gas gases emit a spectrum that depends on the transitions between atomic states, therefore it is a discrete spectrum.

When reviewing the answers, the correct one is:

ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.

Answer:

Thermal energy can be transferred to one object to another in the form of heat. It causes molecules and atoms to collide with each other because of the rising of heat.

Explanation: Well thermal energy is a example of kinetic energy. It is heated by motion. It is heat that can be measured

Answer:

I believe the answer is D: Conductor.

Answer:

A and C are 180 deg out of phase (opposite points on a 360 deg wave)

The two points on the periodic wave  which are 180 degrees out of phase are point A and Point C.

The two points of a wave is said to be out of phase when they show up or down motion at different times.

If a point on the wave, say (X) is reached to the maximum or minimum point before the other point. Then these two points are said to be out of phase.

Also, when the points are 180 degree apart from each other. Which means if a point is in the crest of the wave and other is on the through.

The diagram below shows a periodic wave. In this diagram,

Hence, the two points on the periodic wave  which are 180 degrees out of phase are point A and Point C.

Answer:

Let No be initial no of atoms

N = N0 / 2      after 1 half-life

N = N0 / 4     after 2 half-lives

So after 2 half-lives 20 of the 80 atoms remain

Answer:

negative charge

Explanation:

On an atomic scale, those are called "ions", and negatively charged ions are called anions.

Answer:

The equivalent resistance of the three resistors is 18 ohms.

Explanation:

The value of three resistors are 6 ohms.

We need to find the equivalent resistance of the resistors. In series combination, the equivalent resistance is given by :

R = R₁ + R₂ + R₃ +.....

Put all the values,

R = 6+6+6

R = 18 ohms

Hence, the equivalent resistance of the three resistors is 18 ohms.

Answer:

(This will depend on the type of fuel, I will assume that the fuel is petrol)

First, let's find the expected energy consumption in the US for the next 10 years.

We know that in one year, a person consumes 3.5*10^11 joules.

There are 310,000,00 people on the US

Then the total consumption in one year is:

310,000,000*3.5*10^11 joules = 1.085*10^20 J

In 10 years the consumption is 10 times the consumption of a single year, then the expected energy consumption in the US for the next 10 years is:

10*1.085*10^20 J = 1.085*10^21 J

Now let's find the mass of fuel required.

We know that a liter of petrol has 31,536,000 joules of energy,

And a liter of petrol weights 0.75 kg

To find the number of liters of petrol that we need, we need to find the quotient between the expected energy consumption in the next 10 years and the energy of a single liter of petrol, this is:

N = (1.085*10^20 J)/(31,536,000 j) = 3.44*10^13

We will need  3.44*10^13 liters of petrol.

And the total mass of petrol will be:

M = 3.44*10^13*0.75 kg = 2.58*10^13 kg of fuel.

Answer:

how tightly strung the wire is

-- Make the string tighter or looser.

-- Keep the same length, but make the string thicker or thinner.

-- Touch the string at a point exactly 1/2, 1/3, 1/4, or 1/5 of its length from one end.

Answer:

W = 0 J

Explanation:

The amount of work done by gas at constant pressure is given by the following formula:

[tex]W = P\Delta V[/tex]

where,

W = Work done by the gas

P = Pressure of the gas

ΔV = Change in the volume of the gas

Since the volume of the gas is constant. Therefore, there is no change in the volume of the gas:

[tex]W = P(0\ m^3)\\[/tex]

W = 0 J

Answer:

The collision is inelastic

Explanation:

There are two kinds of collision; elastic collision and inelastic collision. In an elastic collision, both momentum and kinetic energy are conserved.

However, in an inelastic collision, kinetic energy is not conserved. So, when the bumper of two cars collide, the cars come to a stop because the collision is inelastic.

This is Flase

Answer:

Explanation:

Here, we are asked to calculate the average speed in km/minute.

As we know that,

Here,

→ Total distance = 10 km + 10 km

→ Total distance = 20 km

→ Total time = 8 minutes + 2 minutes

→ Total time = 10 minutes

Substitute the values in the formula of average speed,

→ Average speed = Total distance ÷ Total time taken

→ Average speed = 20km ÷ 10 minutes
