Answer:
a) a right triangle, b) x = 0.167 m
Explanation:
a) It is asked to find which geometry figure describes the movement of the ant.
Let's use trigonometry with the angles measured in radians
tan θ = y / x
tan θ = 6/10
θ = tan⁻¹ 0.6
θ = 0.54 rad
this value is equal to the upward slope therefore the geometric body that describes the movement is a right triangle
b) it is asked to find the horizontal displacement for a vertical displacement of y = 0.1 cm x = y / tan tea
x = 0.1 / tan 0.54
x = 0.1668 m
x = 0.167 m

A ball is kicked straight up from the ground with a speed of 10.0 m/s. How long will the
ball be in the air?
The total amount of time the ball would be in the air is 2.04 secs
To determine how long the ball will be in the air,
We will the equation for calculating total time of flight, T
For a projectile motion, the total time of flight of an object is given by
[tex]T = \frac{2usin\theta}{g}[/tex]
Where T is the total time of flight
u is the velocity of projection
θ is the angle of projection
and g is the acceleration due to gravity
From the question,
u = 10.0 m/s
θ = 90° (This is because the ball is kicked straight up)
Put these values into the equation,
[tex]T = \frac{2usin\theta}{g}[/tex]
[tex]T = \frac{2\times 10.0 \ sin90}{9.8}[/tex]
(NOTE: g = 9.8 m/s²)
∴ [tex]T = \frac{2\times 10.0 \times 1}{9.8}[/tex]
[tex]T = \frac{20}{9.8}[/tex]
T = 2.04 secs
Hence, the total amount of time the ball would be in the air is 2.04 secs

A man is pulling a cart to the left with a force of 60 N. A second man is pushing the cart to the left with a force of 30 N. There is a force of 90 N acting on the cart in the opposite direction. What is the net force acting on the cart AND how can the motion of the cart be described?
This cart would move with constant velocity or be at rest because the net force is equal to zero (0), which means the three (3) forces acting on the cart opposes each other.
Let the first force be A. Let the second force be B.Let the third force be C.Given the following data:
Force A = 60 Newton, to the left.Force B = 2 Newton, to the left.Force C = 90 Newton, to the right.To find the net force acting on the cart:
A net force can be defined as the vector sum of all the forces that are acting on a physical object or body.
This ultimately implies that, a net force is a single (one) force that substitutes the effect of all the forces acting on a physical object or body.
Mathematically, net force is given by the following:
[tex]Net \;force = F_1 + F_2 + F_3 + F_4 + .....F_n[/tex]
Where:
F represents each force.[tex]Net\; force = 60 + 30 + (-90)\\\\Net\; force = 90 - 90[/tex]
Net force = 0 Newton
Based on Newton's First Law of Motion, this cart would move with constant velocity or be at rest because the net force is equal to zero (0), which means the three (3) forces acting on the cart opposes each other.

If an astronaut pushes on a box in space, how many forces are involved in this interaction?
A. One
B. Two
C. Three
D. Four
Answer: B. two
Explanation:
There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.
However, In the absence of any forces, no force is required to keep an object moving.
This seems like a simple question, but if you wanted to get technical it would in fact be two forces. As there is still a miniscule amount of gravity.

A 0.5 kg rock and a 150 kg boulder were dropped from a cliff 65 meters high. Which one would hit the ground first ignoring air resistance?
Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. Each step is of uniform height . The mass of each object is a multiple of the base mass : object 1 has mass 3.10 , object 2 has mass 1.46 , and object 3 has mass . When the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. If the objects are then relocated as shown, what is the new total potential energy of the system? Each answer requires the numerical coefficient to an algebraic expression. Each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. Enter only the numerical coefficient. (Example: If the answer is 1.23 ,
The definition of gravitational potential energy would gravitate allows to find the answers for the energy of each object on the highest rung of the ladder are:
a) expression for gravitational potential energy is [tex]U_p = m g \ \Delta y[/tex]
b) Energy value
* Body 1 U_p = 82 J
* Body 2 U_p = 38.6 J
* Body 3 18.5 J
The gravitational potential energy is a configuration energy that represents the amount of work that the system can do for a given configuration, its expression is
[tex]U_p = m g \ \Delta y[/tex]
Where [tex]U_p[/tex] is the gravitational potential energy, m the mass of the body and Δy the difference in height.
In this case it indicates that the minimum height is at the bottom and is equal to zero, the steps of a ladder have a height of approximately y = 15 cm = 0.15 m
They indicate the mass of the bodies are m₁ = 3.10 kg, the mass of the body 2 m₂ = 1.46 kg , the mass of the third object is not observed, suppose it is m₃ = 0.7 kg.
They indicate that the body is placed on the last step, suppose it is a standard 18-step ladder, therefore the total height is
y = # _ steps y_each step
y = 18 0.15
y = 2.70 m
the gravitational potential energy to the capacity of the body is
body 1
[tex]U_p[/tex] = m₁ g Δy₁
U_p = 3.10 9.8 (2.70 -0)
U_p = 82 J
body 2
U_p = 1.46 9.8 ( 2.7-0)
U_p = 38.6 J
body 3
U_pUp = 0.70 9.8 (2.7-0)
U_p = 18.5 J
In conclusion, using the definition of gravitational potential energy, we can find the answers for the energy of each object on the highest rung of the ladder are;
a) expression for gravitational potential energy is [tex]U_p = m g \ \Delta y[/tex]
b) Energy value
* Body 1 U_p = 82.0 J
* Body 2 U_p = 38.6 J
* Body 3 U_p = 18.5 J

a spiral galaxy can be described as what type of shape
Spiral galaxies are also known as twisted collection of stars and gas that have often beautiful shape and are made up of hot young stars.
There are various types of galaxies based on their shapes such as spiral, elliptical, oval etc. The spiral shaped galaxies are called spiral galaxies.
What are galaxies?Galaxies are a groups of stars, dust and dark matter which are connected by the gravitational force. There are billions of galaxies in the universe and each containing trillions of stars. The galaxy nearest to earth is milky way.
The spiral structure that radiate from the galactic disc's core and give spiral galaxies their name. The central bulge, at the ends of which the spiral arms originate, is seen to have an additional component in the shape of a bar-like structure in about two-thirds of all spirals.
Nearly the course of the universe's history, the ratio of barred spirals to barless spirals has probably varied, going from only 10% approximately 8 billion years ago to about a quarter 2.5 billion years ago to over two-thirds of the galaxies in the observable universe at the present.

of the sled after you push it? Please I really need help 60 pointsss
Explanation:
7.7 m/s
1st determine you subject slade to you have a mass of 15 kg being subjected to a force of 180N
so.
180N/15kg=180(kg m)/s^2/15kg=12 ms^2
now determine how long u pushed it
d=0.5 A T^2
sutable the known values getting
2.5 m = 0.5 12 ms^2 T^2
2.5m= 0.6 ms^2 T^2
0.41667 s^2=T^2
0.645497224s=T
the velocity multiply the time by the acceleration giving
0.645497224 s 12 ms^2 =7.745966692 ms.
after rounding the 2 significant u get 7.7 ms
Think about the reasons behind the cost of the Birkin bag and explain why it costs $60,000 in your own words. Do you think that this is a good marketing strategy? Why? Can you think of any other products (clothes / elctronics / anything) that use the same strategy? Does it work?
Answer:
In terms of both price and availability, the Birkin bag is as elusive as it is exclusive. For more than two decades, the bag has been the most sought item in the handbag industry. For such a modest bag, that's a lot of staying power (in looks alone, the design itself takes some 18 hours and is done by a single craftsman).
Of course, it's likely that the bag's rarity is what keeps it at the top of every want list. It is difficult, for example, to stroll into a Hermès store and buy a bag –– even if you could afford to pay the minimum price of $10,000. No, you have to be on an elite list to receive a Birkin.
Explanation:
There are alot more things like the Birkin Bag that use the same marketing skills and it works for alot of companies.

1. Ethan is dragging a bag of grass from the garage to the street on the evening before garbage pick-up day. The diagram at the right is a free-body diagram. It uses arrows to represent the forces acting upon the bag. Each force is labeled according to type. The magnitude of the force is represented by the size of the arrow. Use the free body diagram to determine the net force acting upon the bag. The values of the individual forces are:
Fgrav = Fnorm = 60.5 N
Fapp = 40.2 N
Ffrict = 5.7 N.
From the calculations and the free body diagram, the net force that acts on the body is 34.5 N
What is the net force?The net force refers to the force that is acting on a body. Let us note that the gravitational force and the normal force cancel out each other. Thus the two force that act on the body are the applied force and the frictional force.
Thus;
The net force that acts on the body is;
