For problems 6-9, using the formula net Force = Mass• Acceleration calculate the net force on the object.
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

Sadie rides her bike 1600 m East and then turns around and goes 800 m
West. What is her displacement?
Answer:
(1600 m east) + (800 m west) = (800m east)
Her displacement is 800 m east.
Explanation:
Displacement is the distance and direction between the starting point and ending point,regardless of the route traveled between them.
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.
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

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
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.
PLEASE ACTUAL HELP NO SPAMS OR FALSE ANSWERS
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?
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.

The image results when the object is located between 2f (2 focal lengths) and f (the focal point) of a convex lens will be real, inverted, and enlarged.
What is a convex lens ?An optical lens is made up of two spherical surfaces is a convex lens The lens is called a biconvex lens or simply convex lens if those surfaces are curved outwards.
Converging lens is another name for it. It's because it brings all the light rays that are parallel to the primary axis together at the focus point (F).
The image results when the object is located between 2f (2 focal lengths) and f (the focal point) of a convex lens will be real, inverted, and enlarged.
Hence, option C is correct.

5.) What is the missing element? *
a. Hydrogen
b. Helium
c. Boron
d. Oxygen
Answer:
Explanation:
This question is showing a stoichiometric reaction. But the out put is Helium and nitrogen. while the input has Hydrogen and something else. Hydrogen doesn't turn into different elements. So I think the question is wrong. But, He is missing , and so is the nitrogen, but since that's not a choice, maybe they hope you'll put He ?? :/ But like I said , the question is just wrong.

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
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.

A .100 kg bullet is flying at 200 m/s. How much energy is the bullet storing due to its motion?
KE = 2000 J
Explanation:
KE = (1/2)mv^2
= (1/2)(0.100 kg)(200 m/s)^2
= 2000 J
A person in a kayak starts paddling, and it accelerates from 0 to 0.509 m/s in a distance of 0.555 m. If the combined mass of the person and the kayak is 63.4 kg, what is the magnitude of the net force acting on the kayak
Answer:
the magnitude of the net force acting on the kayak is 14.77 N.
Explanation:
Given;
initial velocity of the kayak, u = 0
final velocity of the kayak, v = 0.509 m/s
distance traveled by the kayak, d = 0.555 m
combined mass of the person and kayak, m = 63.4 kg
Determine the acceleration of the kayak by using the following kinematic equation;
v² = u² + 2ad
(0.509)² = 0 + (2 x 0.555)a
0.259081 = 1.11a
a = 0.259081 / 1.11
a = 0.233 m/s²
The magnitude of the net force acting on the kayak is calculated by using Newton's second law of motion;
F = ma
F = 63.4 x 0.233
F = 14.77 N
Therefore, the magnitude of the net force acting on the kayak is 14.77 N.

A marble block of mass 2 kg lying on ice when given a velocity of 6 m/s is stopped by a friction in 10s then what is the coefficient of friction?
Answer:
[tex]\mu=0.06[/tex]
Explanation:
Given that,
Mass of a block, m = 2 kg
Velocity of the block, v = 6 m/s
It stopped in 10 s
We need to find the coefficient of friction.
The frictional force is balanced by the opposing force such that,
[tex]\mu mg=ma\\\\\mu=\dfrac{a}{g}[/tex]
Where
a is acceleration, a = 6/10 = 0.6 m/s
So,
[tex]\mu=\dfrac{0.6}{10}\\\\\mu=0.06[/tex]
So, the coefficient of friction is equal to 0.06.
