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,

Unbalanced forces cause a change in motion.
How do you know this?
Answer:
This happens in two ways. If an object is at rest and an unbalanced force pushes or pulls the object, it will move. Unbalanced forces can also change the speed or direction of an object that is already in motion.

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.
Answer: the divergent one goes where it looks like there a crack because when you think about divergent it means dividing like seperating.(igneous rock) is where the divegent one goes.
the one that is no plate boundary is sedimentary rock and it occurs by because there is nothing there for it todo there

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.

1. You and your forensics team are working a crime scene of a 19 year-old female who was found in the woods behind
the local hospital. She is found lying on her torso (face down), but lividity is present on the dorsal (back) side of the
victim.
What can you conclude about the victim/situation?
Answer:
You could conclude the 2nd fact
Explanation:
The conclusion will be that she died before 4-5 hours and she has been poisoned.
What will be the conclusion?It is found that the 19 years old female was found in the woods and she finds lying her face down and also the lividity is present on the backside of the woman.
First of all, we will understand what is lividity. Lividity is the process in which the color of the body changes and it starts after 1-4 hours of death.
lividity occurs when the blood does not pump the blood in the body and the blood is collected to the particular area where the gravity is acting.
If the body is found face down with signs of blanching on its back, it suggests to forensic scientists that the individual had likely died on their back and been moved.
If the body color changes to red cherry then it can be predicted that the individual died from carbon mono oxide poisoning
If the body color changes to pink it can be due to cyanide poisoning.
Thus the conclusion will be that she died before 4-5 hours and she has been poisoned.

is there a "real" simple machine that has an efficiency of 100%?
Answer:
NO
Explanation:
No, a machine cannot be 100% efficient. This is due to the movement of the moving parts siding against each other and causing friction. This friction is the one that creates heat and causes wear and tear between moving ports f the machine hence making the machine to decrease in efficiency with time

Two ropes support a load of 478 kg. The two ropes are perpendicular to each other, and the tension in the first rope is 2.2 times that of the second rope. Find the tension in the second rope. The acceleration of gravity is 9.8 m/s 2 . Answer in units of N.
Answer:
T₂ = 1937.68 N
Explanation:
First, we will calculate the weight of the object:
[tex]W = mg = (478\ kg)(9.81\ m/s^2)\\W = 4689.18\ N[/tex]
Now, we will calculate the resultant tension in the ropes. Since the ropes are perpendicular. Therefore,
[tex]T = \sqrt{T_1^2+T_2^2}\\[/tex]
where,
T = Resultant Tension
T₁ = Tension in rope 1
T₂ = Tension in rope 2
According to the given condition tension in the first rope is 2.2 times the tension in the second rope:
T₁ = 2.2 T₂
Therefore
[tex]T = \sqrt{(2.2T_2)^2 + T_2^2}\\\\T = 2.42T_2[/tex]
Now, the weight of the object must be equal to the resultant tension for equilibrium:
[tex]T = W\\2.42T_2 = 4689.18\ N\\\\[/tex]
T₂ = 1937.68 N

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.

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.

Explain how the Indian and Asian plates met and the kind of boundary that formed on their meeting. Describe what happened as a result and tell why.
Answer:
This immense mountain range began to form between 40 and 50 million years ago, when two large landmasses, India and Eurasia, driven by plate movement, collided. ... Artist's conception of the 6,000-km-plus northward journey of the "India" landmass (Indian Plate) before its collision with Asia (Eurasian Plate).
Explanation:
India has forcefully introduced 40 to 50 million years ago. The landmass of India was once present south of the Equator, but the northern margins began to collide against the Eurasian plate.
Tethys sea was one of the vast oceans, which separated the landmass of India and Asia. Pangaea destruction occurred 200 million years ago, which caused India to forge northward.
Around 80 million years ago, India was approximately 6,400 kilometers south of the Asian continent. The landmass of India when reached the Eurasian plate, it collided because of the same density.
Thus, the plates of Eurasian and Indian landmass collided and caused the forming of hills. The Indian landmass continued to push towards the north, which caused the hills to convert into mountains.

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.

Answer:
15.4
Explanation:
770x14% = 107.8
rearrange f =kx to get k (constant)
k = f/x
x is the distance stretched , so 42 - 35 =7
so 107.8/7 =15.4
can someone double check
Answer:
k = 44000 N/m is the answer.
Explanation:
Gravitational Potential Energy = 770J
Elastic Potential Energy = 14% of 770J
= 14/100 × 770
= 107.8J
Extension (x) = 42 - 35 = 7cm = 7 × 10⁻²m
To find the spring constant (k)
Elastic Potential Energy Formula:
[tex]U = \frac{1}{2}kx^2[/tex]
107.8 = 1/2 × k × (7 × 10⁻²)²
215.6 = 0.0049 × k
k = 215.6/0.0049
k = 44000 N/m
