Two people travel from Columbus to Cleveland, one by car at an average velocity of 90km/h, and one by plane at an average velocity of 300km/h. Can their displacements be equal
Answer:
Explanation:
Yes , their displacement may be equal .
Suppose the displacement is AB where A is starting point and B is end point .
The car is covering the distance AB by going from A to B on straight line . On the other hand plane goes from A to C , then from C to D and then from D to B . In this way plane reaches B from A on a different path which is longer than path of the car . In the second case also displacement of plane is AB . In the second case distance covered is longer but displacement is same that is AB .

Why do you think lightning is so dangerous if it strikes a person?
Do you remember the old fashioned flashlights, before there were LEDs ?
They had two or three heavy batteries in the tube, and one little tiny glass light bulb in the middle of the little headlight in the front. When the batteries were fresh, that little light bulb gave out a nice bright beam of light, and drew about 0.7 Amperes from the batteries. That's the number I want you to remember for a couple of minutes: Flashlight bulb, 0.7 Amperes.
-- The wiring (nerves) that operate your heart can go haywire, and your heart can stop or go crazy, if 0.015 Amp of current or more happens to pass close by it.
-- The muscles in your arms or legs, or your diaphragm that makes you breathe, can lock up so that you can't control them, if 0.1 Amp of current or more happens to pass by them. If that current is 0.5 Amp or more and passes close to a muscle, the muscle can lock up so violently that it breaks the arm- or leg-bone that it's attached to.
Lightning is electric current flowing between a cloud and the ground. If anything is in the path it wants, it just flows right on through.
Lightning may flow in either direction ... up to the cloud or down to the ground. It really doesn't make any difference. The effects are the same, on anything it decides to flow through.
The current in a typical, average lightning bolt is 30,000 Amperes. A lot of them are bigger.
Current flowing through anything causes heat to be generated.
The more current = the more heat.
-- Lightning flowing through the wall of a house generates enough heat inside the wall to make the wall explode.
-- Lightning flowing through the juice inside a tree generates enough heat to boil the tree juice, and explode the tree.
-- Lightning flowing through the air heats a skinny tube of air so hot and so fast that the air explodes. That makes a strong sound wave in the air, that can be heard from miles away. It's called "thunder".
-- A person is made of lots of nice soft, moist, mushy stuff, water, juices, and air. A thousand Amperes flowing through it all can do a fast, efficient, complete job of heating it, boiling it, cooking it, exploding it, and tearing it to pieces.
Sounds dangerous to me.
match the quote about working in government to the correct branch. Then name

Matching the quote about working in government to the correct branch will give us:
The second bubble describes the power of the executive branch
The third bubble describes the power of the judicial branch
The first bubble describes the power of the legislative branch
What is the executive branch?The power of the Executive Branch is vested in the President of the United States, who also acts as head of state and Commander-in-Chief of the armed forces.
The executive branch or is the part of government that enforces law, and has responsibility for the governance of a state.
In political systems based on the principle of separation of powers, authority is distributed among several branches (executive, legislative, judicial)—an attempt to prevent the concentration of power in the hands of a single group of people.
The executive enforces the law as written by the legislature and interpreted by the judiciary.
The executive can be the source of certain types of law, such as a decree or executive order. Executive bureaucracies are commonly the source of regulations.
What is the judicial branch?The third branch of government is the Judicial branch. The Judiciary is made up of courts -- Supreme, Circuit, the magistrate (local) and municipal (city) courts. The Judicial branch interprets the laws.
The state judges are elected by the citizens rather than being appointed. They also run for their office as members of a political party.
The judiciary is the system of courts that interprets, defends, and applies the law in the name of the state. The judiciary can also be thought of as the mechanism for the resolution of disputes.
In many jurisdictions, the judicial branch has the power to change laws through the process of judicial review.

A)This part controls the amount of light entering the eyes. A= Iris B= Pupil Give reason for your answer.
Answer:
Iris
Explanation:
Iris can be described as a part of the eyes which regulates the amount of light that enters the eye. The iris is made up of various muscles that control the size of the pupil
When a person is in a well-lighted room, the iris decreases the size of the pupil so that a low amount or medium amount of light is absorbed into the pupil. Also when an individual steps into a dark room the iris increases the size of the pupil so that a high amount of light penetrates the pupil.
Hence without the iris the amount of light that enters the eye cannot be controlled.

If a spring is stretched to twice the lengtj of its equilibrium position, by what factor does the energy stored in the spring change?
Answer:
the energy increases 4 times
Explanation:
A spring has an elastic potential energy that is given by the expression
K_e = ½ K (x-x₀)²
where x is the distance from the equilibrium point and k is the return constant
if the spring is stretched at x-x₀ = 2x₀, the energy value
K_e = ½ k (2x₀)²
K_e = ½ k 4 x₀²
K_e = 4 (½ k x₀²)
[tex]\frac{K_e}{ \frac{1}{2} k x_o^2}[/tex] = 4
therefore the energy increases 4 times
The energy stored in the spring changes by a factor of 4
The formula for calculating the energy stored in the spring is expressed as:
[tex]E=\frac{1}{2}ke^2[/tex]
If the spring is stretched to twice the length of its equilibrium position
[tex]E_2=\frac{1}{2}(2k)^2\\E_2=\frac{1}{2}4k^2[/tex]
Take the ratio of the energy stored in the spring
[tex]\frac{E_2}{E} =\frac{1/2(4kx^2)}{1/2kx^2}\\ \frac{E_2}{E} =\frac{4}{1}\\E_2 = 4E[/tex]
This shows that the energy stored in the spring changes by a factor of 4

give some practical application of center of mass
Answer:
The center of mass of the human body depends on the gender and the position of the limbs. In a standing posture, it is typically about 10 cm lower than the navel, near the top of the hip bones. In this Atom, we will learn how to measure the COM of a human body.
Explanation:
In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion.
In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distribution of separate bodies, such as the planets of the Solar System, the center of mass may not correspond to the position of any individual member of the system.
The center of mass is a useful reference point for calculations in mechanics that involve masses distributed in space, such as the linear and angular momentum of planetary bodies and rigid body dynamics. In orbital mechanics, the equations of motion of planets are formulated as point masses located at the centers of mass. The center of mass frame is an inertial frame in which the center of mass of a system is at rest with respect to the origin of the coordinate system.
