Write a short paragraph that explains how a sport using a ball would be played differently on a planet of your choice. For example, how would gravity affect a basketball game on Saturn? Or how would gravity affect a baseball game on Mercury?
(Doesnt have to be a full paragraph answer I just need a gist of what it is)
on a different planet I would play a sport similar to soccer. The main difference is that there is zero gravity. To win the game u have to get the ball into the other person's net first.

what does it mean for a disease to be X linked?
Answer:
X-linked is a trait where a gene is located on the X chromosome. Humans and other mammals have two sex chromosomes, the X and the Y. In an X-linked or sex linked disease, it is usually males that are affected because they have a single copy of the X chromosome that carries the mutation.

Is the potential energy on the surface of Earth zero?If not,what will be it's value?
Answer:
Potential energy does not have an absolute measurement. It is always relative to some reference point. Gravitational potential always increases when you go up and decreases when you go down. But the choice of a zero point is arbitrary.
If you’re dropping objects onto the ground, then choosing the ground as a zero point makes the calculations easier. But you could just as easily make the zero point the top of Mt. Everest, and all the answers would turn out the same. Up still means more energy and down means less, but now the PE of an object at sea level would have a negative sign, but not as negative as an object ten meters above sea level.
So everything would still work fine.
In fact, planetary astronomers take this idea to extremes. Instead of the top of Mt. Everest, they set the zero point for potential energy as infinitely high—so far “up” that gravity is so weak that going “up” another kilometer doesn’t gain you any energy. Then the value for potential energy everywhere else in the universe anywhere near a planet has a negative sign, but just as before, all the answers in relative terms turn out fine.

Calculate by how much a spring with spring constant 1.2N/m has been squashed when it has stored 76J,
Answer:
11.25 m
Explanation:
From the question given above, the following data were obtained:
Spring constant (K) = 1.2 N/m
Energy (E) = 76 J
Compression (e) =?
Energy stored in a spring is given by the following equation:
E = ½Ke²
Where:
E => Energy stored in the spring.
K => spring constant
e => Extention or compression
With the above formula, we can obtain how much the spring has been squashed as follow:
Spring constant (K) = 1.2 N/m
Energy (E) = 76 J
Compression (e) =?
E = ½Ke²
76 = ½ × 1.2 × e²
76 = 0.6 × e²
Divide both side by 0.6
e² = 76 / 0.6
Take the square root of both side.
e = √(76 / 0.6)
e = 11.25 m
Thus, the spring has been squashed by 11.25 m

1.Galileo conducted experiments from the top of the Leaning Tower of Pisa. If he dropped a piece of burlap tied into a ball with twine and a 2-pound rock at the same time, what would he have seen and why? (5 points)
Answer:
The time for both of the balls to reach the ground would be the same.
Explanation:
If no air resistance is present, the rate of descent depends only on how far the object has fallen, no matter how heavy the object is. This means that two objects will reach the ground at the same time if they are dropped simultaneously from the same height. ... In air, a feather and a ball do not fall at the same rate.
3) In the numbers: 0, 1, 2, 3, 4, 5; which number will you read properly
in mirror? Explain
Answer:
it'll be 0
Explanation:
The acceleration of the object may be zero and the velocity of the object may not be equal to zero
Sure. That's true when ANY object is moving in a straight line at a steady speed.

As an astronaut travel far away from earth her weight
Explanation:
As an astronaut travel far away from the earth her weight Decreases because weight depends upon the acceleration due to gravity and in space there is no gravity.
An archer defending a castle is on an 15.5 m high wall. He shoots an arrow straight down at 22.8 m/s. How much time does it take to reach the ground? (Unit = s) Watch your minus signs!
Answer:
about 602 milliseconds
Explanation:
The motion can be approximated by the equation ...
y = -4.9t^2 -22.8t +15.5
where t is the time since the arrow was released, and y is the distance above the ground.
When y=0, the arrow has hit the ground.
Using the quadratic formula, we find ...
t = (-(-22.8) ± √((-22.8)^2 -4(-4.9)(15.5)))/(2(-4.9))
= (22.8 ± √823.64)/(-9.8)
The positive solution is ...
t ≈ 0.60195193
It takes about 602 milliseconds for the arrow to reach the ground.
which of the following correctly describes the hierarchy of genetic material within a cell
Answer: D- Each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA
Explanation:
A macromolecule is a large molecule that is made of many smaller units. Chromosomes are macromolecules that contain all of the genetic information in a cell. Chromosomes are each made of two smaller units called chromatids. Chromatids are each made up of molecules of DNA. Therefore, the correct description of the hierarchy of genetic material in a cell is that each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA. The structures become more and more microscopic as one moves down the hierarchy.
Kinetic energy increases as:
A. Mass increases and velocity decreases.
B. Mass decreases and velocity increases.
C. Both mass and velocity increase.
D. Both mass and velocity decrease.
Kinetic energy formula is: 1/2 mv^2
M = mass
V = Velocity
So as kinetic energy increases, mass increases and velocity increases because mass and velocity are directly proportional to each other.
How many degrees are there between the direction of motion and the force of friction?
A. O
B. 270
C. 90
D. 180
The correct option is (d).
Angle should be 180° between the direction of force and the direction of motion of a body as work done is equal to force multiplied by displacement multiplied by cosx.
Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.A force known as friction prevents relative motion between surfaces that are in touch. One of the more basic features of friction is that it always runs parallel to the surfaces with which it makes contact and opposes any motion or attempted motion of the systems with respect to one another.What is the direction of friction force?When a force is applied to stop it from moving, frictional force provides resistance. As a result, it always moves in the opposite direction of an item in motion. Friction acts on the right when force is applied to the left.Learn more about direction of friction force brainly.com/question/24322020

what allows electrons to move through it easily
Answer:
materials that allow many electrons to flow freely are caused conductors such as copper, silver, aluminum, hydrochloric solution, sulfuric acid, and salt water. in contrast materials which allow few electrons to flow are called insulators such as plastic, rubber, glass, and dried paper.

1.which type of image is right side up but left and right are reversed
A.real
B.virtual
2.Real images are:
A.always inverted
B.magnified or diminished
C.can be obtained on screen
D.all the above
Answer:
see below
Explanation:
1) B, virtual because the when you stand in front of a mirror, the image formed is virtual and Image is laterally inverted
2) D because, when using converging lens , real image is formed, it is inverted and it can also be magnified or diminished when the object is placed at different focal length.
real image can be captured on the screen because light rays meet at the image position
when using converging lens, the image formed if it is virtual is upright.
hope this helps
