For problems 6-9, using the formula net Force = Mass• Acceleration calculate the net force on the object.
Answers
Answer:
Find answers below
Explanation:
Mathematically, force is given by the formula;
Force = mass * acceleration
Given the following data;
6. Mass = 8 kg
Acceleration = 2 m/s²
Force = 8 * 2
Force = 16 Newton
7. Mass = 5 kg
Acceleration = 2 m/s²
Force = 5 * 2
Force = 10 Newton
8. Mass = 8 kg
Acceleration = 8 m/s²
Force = 8 * 8
Force = 64 Newton
9. Mass = 200 kg
Acceleration = 3 m/s²
Force = 200 * 3
Force = 600 Newton

Draw a circuit that uses the resistors listed below as well as a 12V battery source. For your circuit, determine (a) the total resistance, (b) the total current, and (c) the total voltage over the entire system.
Answers
Answer: hello your questions lacks the required resistor values therefore i will provide a general answer using an example
answer : a) 14 ohms b) 0.86 amps c) 10.32 V
Explanation:
Assuming the resistors are : 3 ohms , 4 ohms and 5 ohms
Voltage source = 12V
Assuming that the Resistors are in series
a) Determine Total resistance
Req = R1 + R2 + R3
= 3 + 4 + 5 = 14 ohms
b) Total current
Ieq = V / Req
= 12 / 14 = 0.86 amps
c) The Total Voltage over the entire system
Vt = ∑ Voltage drops
= ( 0.86 * 3 ) + ( 0.86 * 4 ) + ( 0.86 * 5 )
= 10.32 V

Answer:
The speed decreases and the frequency remains the same.
Explanation:
Had it for a castle learning assignment, guessed and got it correct.
The speed of a light ray decreases and its frequency remains the same when it passes from glass into water.
What is the speed of light?The speed of light, also known as the velocity of light, is a fundamental constant of nature and is one of the most well-known physical quantities. It is defined as the speed at which electromagnetic radiation (light) travels through a vacuum, which has a constant value of 299,792,458 meters per second (m/s).
This speed is considered to be the fastest that anything can travel in the universe, and it is a critical component in many physical and biological processes. The speed of light is used in a wide range of scientific and technological fields, including optics, electronics, astronomy, and quantum mechanics. It is considered to be a universal constant and does not change with time, distance, or the medium through which it travels.

The graph shows the layers of Earth's atmosphere. Which statement best describes the relationship between temperature and altitude in the atmosphere?
A. The relationship between temperature and altitude is variable and unpredictable.
B. Overall, the temperature of the atmosphere increases with altitude.
C. The relationship between temperature and altitude is different in each zone of the atmosphere.
D. Temperature decreases with altitude until the stratosphere is reached, and then it increases from there.
Answers
Answer:
The best statement which describe this is actually:
D. Temperature decreases with altitude until the stratosphere is reached, and then it increases from there.
Explanation:
From the graph shown, it could be seen that, temperature decrease with height. The higher the height, the lower the temperature. For example, from the graph, when the height was around 50 km, the temperature was within the range of -10⁰C to 0⁰C. On the other hand, when the height increases around 78 km, the temperature decreases to the range of to -70 ⁰C to -80⁰C
Astronomers have measured that there is more helium in the universe than can be explained by the fusion in stars over the last 13 billion years. How do they think the extra helium got into the universe
Answers
Answer:
From big bang and stars.
Explanation:
The extra helium got into the universe through big bang and fusion reaction that occur in stars. Our universe formed about 13.7 billion years ago with big explosion, this event is known as big bang. The fusion of hydrogen nuclei in the stars produces helium and energy so we can say that most of the extra helium got into the universe through fusion reaction that occur in the stars continuously.

in 4 seconds, a cheetah can run 112 meters. How fast does this cheetah have to be running? A: 448 m/s || B: 28 m/s || C: 56 m/s || D: 36 m/s
Answers
Answer:
B: 28m/s
Explanation:
Use the speed formula
Speed =distance / time
Answer:
[tex]\boxed {\boxed {\sf B. \ 28 \ m/s}}[/tex]
Explanation:
If we want to know how fast the cheetah is running, we need to calculate its speed. This is the rate at which an object moves and the formula is distance divided by time.
[tex]s=\frac{d}{t}[/tex]
The cheetah ran 112 meters in 4 seconds.
d= 112 m t= 4 sSubstitute the values into the formula.
[tex]s=\frac{112 \ m}{ 4\ s}[/tex]
Divide.
[tex]s= 28 \ m/s[/tex]
The cheetah's speed is 28 meters per second and choice B is correct.
for every 1000 joules or useful energy output, the heater wastes 100 joules, find the input energy of the heater.
Answers
Answer:
the Input Energy is 1,100 J
Explanation:
Given;
useful energy, = 1000 J
energy wasted, = 100 J
The total or input energy is given as;
Input Energy = useful energy + energy wasted
Input Energy = 1000 J + 100 J
Input Energy = 1,100 J
Therefore, the Input Energy is 1,100 J

First, evaluate these three models. One represents fission, one fusion, and one radioactive decay. Write three sentences about each one according to the following framework:
---State what reaction the model represents, including what it demonstrates about mass and/or energy.
---State whether you think the model accurately represents the reaction. Explain why or why not.
---Suggest one way to improve the model.
Model A: Two sponge balls representing two atoms are soaked in water. You hold one ball, and your friend holds the other. Then you press the two balls together. As you press them together, water leaks out. What type of reaction does this model represent?
Model B: You draw a tree diagram showing a large atom splitting into two parts and neutrons being released. Your diagram also shows the released neutrons hitting other large atoms, which then each split in two and release more neutrons, which hit more large atoms, and so on. What type of reaction does this model represent?
Model C: You have 100 candies with the letter "M" on one side. You pour the candies into a pan. You count and remove all the candies with the "M" facing upward. Then you shake the pan and again count and remove all the candies with "M" facing upward. You shake, count, and remove candies four more times. What type of reaction does this model represent?
Answers
When energy is transferred from system to surrounding then the corresponding reaction known as exothermic reaction in Modle A when we press the ball(atom) the water(energy) is transferred into surrounding hence it is an exothermic reaction.
When a single atom disintegrate to give two or more atom with radioactive substance then the corresponding reaction know as Nuclear Fission reaction. hence Modle B represents Nuclear fission reaction.
The Model C represents Radioactive decay, So in the given example or model the water is playing role of radiation through which we are removing the candies having M on upside.

A roller coaster goes down a slope with a starting speed of 5 m/s then 6
seconds later at the bottom of the slope the roller coaster is moving at a
speed of 27 m/s. What is the acceleration of the roller coaster? **Round to
1 decimal place**
Answers
Answer:
Acceleration = 3.67 m/s²
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Given the following data;
Initial velocity, u = 5 m/s
Final velocity, v = 27
Time, t = 6
To find the acceleration;
Acceleration = (v - u)/t
Acceleration = (27 - 5)/6
Acceleration = 22/6
Acceleration = 3.67 m/s²
Justin mixed two cups of lemon juice and two cups of sugar with a gallon of water in a pitcher. What happened to the lemon juice, sugar, and water?
Answers
Answer:
The correct answer is - Lemon juice hydrolyzes sugar and dissolves it faster and creates a solution.
Explanation:
When mixing lemon juice and sugar in water are mixed together, the lemon juice dissolves the sugar faster as it has citric acid that hydrolyzes sucrose molecules of sugar in glucose and fructose.
This mixing of all three lemon juice, water, and sugar form a solution. Here in this solution, water is solvent, and sugar and lemon juice are solutes. The quantity of all three determined the nature of the solution if it will be acidic or more diluted.
