After reading a book, Julio looks out of the window and sees clouds in the distance. Which change allows Julio to clearly see the clouds after looking at his book? His corneas become flatter. His lenses change shape. His optic nerves begin sending signals. His vitreous humor becomes denser.
Answer:
Lens change
Explanation:
by changing the shape of the lens the rays from the clouds will be able to refract correctly in the lens then create the correct upside-down image on the retina.
Hope it helped

What type of Circuit do they use in a home? WHY ? (Simple circuit / Parallel circuit / Series circuit) helpp
Answer:
Parallel
Explanation:
Most standard 120-volt household circuits in your home are (or should be) parallel circuits. Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit.
Hope that helps :)
Which equation determines the acceleration of an object moving in a straight line?
You must calculate the change in speed per unit of time.

Acceleration = ( initial speed - final speed ) / time
Acceleration = time / ( initial speed - final speed)
Acceleration = time / ( final speed - initial speed)
Acceleration = ( final speed - initial speed ) / time

How can Newton’s law of action–reaction best be applied to explain the movement of a rocket?
Answer:As the fuel burns,gases push against the rocket, moving it upward
Explanation: here’s a tip download socratic take a pic of the question then scroll down there should be a quizzes with the answer for you quizzes is good when you want answers to a Science or language arts/reading so yea
Burning fuel in a rocket causes a push that propels the rocket forward from the front. The exhaust gas is pushed rearward in an equal and opposite direction as a result.
What is Newton’s law?The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact.
The following is a paraphrasing of these laws: Unless a force acts upon a body, it remains at rest or in continual straight-line motion.
The creation of thrust by a rocket engine can be understood via Newton's third law. In a rocket engine, a fuel and an oxidizer are burned to produce hot exhaust gas.
The hot exhaust gas from the rocket accelerates to the back of the rocket after passing through the nozzle.
Thus, this way, Newton’s law of action–reaction best be applied to rocket movement.

What is the speed of a 180 g ball if its kinetic energy is 100 J?
Answer:
Velocity, V = 33.33 m/s
Explanation:
Given the following data;
Mass = 180grams to kilograms = 180/1000 = 0.18 kg
Kinetic energy = 100J
To find the speed;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
100 = ½*0.18*V²
Cross-multiplying, we have;
200 = 0.18*V²
V² = 200/0.18
V² = 1111.11
Taking the square root of both sides, we have;
Velocity, V = 33.33 m/s

Explain how you can locate the Pole Star with the help of Ursa Major?
Answer: Pole star can be located using Ursa Major by extending an imaginary line from the last two stars towards the North direction.
Explanation:
Answer:
The pole star can be located using the Ursa Major constellation, by imagining a line towards the Northern direction connecting two stars present at the end of the bowl, This imaginary line meets Pole Star. The length of the imaginary line from the bowl is about five times the distance between the two stars of the bowl.

What does each system help you do?
1 Somatic Nervous System
2 Autonomic Nervous System
3 Sympathetic Division
4 Parasympathetic Division
5 Hormones
Explanation:
1.The somatic nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles.
2. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, pupillary response, urination, ect...
3. Sympathetic Division is a term used by researchers and medical practitioners to describe the subdivision of the autonomic nervous system (that controls involuntary and automatic physical reactions) that responds to emergency situations by mobilizing and controlling the energy necessary to cope with the situation.
4. The part of the autonomic nervous system that tends to act in opposition to the sympathetic nervous system, as by slowing down the heart and dilating the blood vessels. It also regulates the function of many glands, such as those that produce tears and saliva.
5. a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action.

Do you think we might have problems with not enough water to supply our needs (water scarcity) in the
ture? Why or why not? If you answered yes, what might the causes be?
Answer:
Water scarcity (water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. Humanity is facing a water crisis, due to unequal distribution (exacerbated by climate change) resulting in some very wet and some very dry geographic locations, plus a sharp rise in global freshwater demand in recent decades driven by industry. Water scarcity can also be caused by droughts, lack of rainfall, or pollution. This was listed in 2019 by the World Economic Forum as one of the largest global risks in terms of potential impact over the next decade.[1] It is manifested by partial or no satisfaction of expressed demand, economic competition for water quantity or quality, disputes between users, irreversible depletion of groundwater, and negative impacts on the environment.[2] Two-thirds of the global population (4 billion people) live under conditions of severe water scarcity at least 1 month of the year.[3][4][5][6] Half a billion people in the world face severe water scarcity all year round.[3] Half of the world's largest cities experience water scarcity.[5]

What is momentum? And it’s types?
Answer:
Momentum is the product of mass and velocity. The two types of momentum are angular and linear.
Explanation:
Answer:
Explanation: (Momentum is mass * velocity. Its units, in the SI system are kilogram meter per second) What is Inertia?
In physics, momentum is the product of mass and velocity. The greater the product of this equation, the greater the momentum. In science, there are two types of momentum: angular and linear, which concern different types of moving objects. However, that is not where the definition stops. The word momentum is also used as part of everyday speech, and is one of the very few physics concept whose metaphorical definition is the same as its actual one.
