Two resistors, R 1 and R 2 , are connected in parallel. R 2 =221.0 ohms, and the equivalent resistance of the combination is 120.7 ohms. What is the value of R 1 ? (Unit = ohm)
Answer:
Explanation:
When resistors are connected in parallel combination, then equivalent resistance is given by,
[tex] \to \quad \bf{ \dfrac{1}{R_1} + \dfrac{1}{R_2} =\dfrac{1}{R_p}}[/tex]
Inserting values,
[tex] \to \quad \bf { \dfrac{1}{R_1} + \dfrac{1}{R_2} =\dfrac{1}{R_p} } \\ \\ \to \quad \bf { \dfrac{1}{R_1} + \dfrac{1}{221} =\dfrac{1}{120.7} } \\ \\ \to \quad \bf { \dfrac{221+R_1}{(R_1)(221)} =\dfrac{1}{120.7} } \\ \\ \to \quad \bf { \dfrac{221+R_1}{221R_1} =\dfrac{1}{120.7} } \\ \\ \to \quad \bf { 120.7(221+R_1) = 221R_1(1)} \\ \\ \to \quad \bf { 26674.7 + 120.7R_1= 221R_1} \\ \\ \to \quad \bf { 26674.7= 221R_1- 120.7R_1} \\ \\ \to \quad \bf { 26674.7 = 100.3R_1} \\ \\ \to \quad \bf { \dfrac{26674.7 }{100.3} =R_1} \\ \\ \to \quad\underline{\boxed{ \bf { 265.9 \; \Omega=R_1}}} \\ [/tex]

How much work is done by 0.070 m3 of gas, when the volume remains constant with pressure of 63 x 105 Pa?
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

9. Bryce drove his car 10 km from his house to Belle Plaine. It took him 8 minutes. He got stopped at a long
traffic light on the return home and so he took 2 minutes longer on the return trip. What was Bryce's average
speed in km per minute? (3 pt)
Answer:
2 km/minuteExplanation:
Here, we are asked to calculate the average speed in km/minute.
As we know that,
Average speed = Total distance ÷ Total time takenHere,
→ Total distance = 10 km + 10 km
Because, he first drove 10 km from his house to Belle Plaine and then he again came back to his house.→ 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
→ Average speed = 2 km per minutecan someone help? i don’t need 14

Which is not true about the role of gravity in the formation of planets?
Dust and gas particles that were attracted to each other began to rotate into a protoplanetary disk.
Gravity between planetesimals caused them to join together into conglomerate clumps. Our solar system is the only place in the universe where gravity played a key part in the formation of planets.
Gravity of larger objects in orbit around the sun attracted, and cleared the orbital path of, smaller planetesimals, gas, and dust.
Our solar system is the only place in the universe where gravity played a key part in the formation of planets.

1- Three 6-ohms resistors in a series circuit give equivalent resistance of
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.
What is the intensity of sound produced by an elephant's call if it has a power of 0.45 W and you are standing 32.5 m away from the lumbering beast
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
Determine the mass of fuel required for the expected energy consumption in the United States for the next 10 years:
Provide the energy use per person per year in the United States = 3.5 × 1011 joules.
Base your calculations on a current population of 310,000,000.
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.

What is the difference between the spectrum of an incandescent solid and the spectrum of an incandescent gas?
Incandescent solids emit bright-line spectra; incandescent gases emit continuous spectra.
Incandescent solids emit one wavelength; incandescent gases emit several wavelengths.
Incandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.
Incandescent solids emit scattered spectra; incandescent gases emit continuous spectra.
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.
According to the graph, how many atoms would remain after two half-lives?
20 atoms
80 atoms
40 atoms
50 atoms
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

The diagram below shows a periodic wave. Which two points on the wave are 180 degrees out of phase?
Please explain as well, thanks so much
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.
When two points of wave are out of phase?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,
A and I are the end points of the periodic wave.B,C,D,E,F and G are the other points on the periodic wave.Here, the point A and C are opposite point of each other. So they are 180 degrees out of phase.Hence, the two points on the periodic wave which are 180 degrees out of phase are point A and Point C.

2. Identify a point in the diagram where a divergent boundary is occurring and explain how it is interacting with the rock cycle.
3. Identify a point in the diagram where the rock cycle is occurring without a plate boundary and how it is interacting with the rock cycle.

Explanation:
The bumper cars crash into each other and stop. Explain why both bumper cars stop after the crash. [4marks]
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.
