Computers are widely used for modeling weather systems because because weather systems are too complicated to be accurately predicted using small-scale. Hence option A is correct.
What is whether system ?Weather refers to the condition of the atmosphere and includes terms like how hot or cold, wet or dry, quiet or stormy, clear or foggy, etc. The troposphere, which is the lowest part of Earth's atmosphere and lies just below the stratosphere, is where most meteorological events take place. Climate is the phrase for the average of atmospheric conditions over longer periods of time, whereas weather is the term for day-to-day temperature, precipitation, and other atmospheric factors. Without more explanation, "weather" is typically taken to refer to the weather on Earth.
Differences in air pressure, temperature, and moisture from one location to another influence the weather. The Sun's angle at any given location, which changes with latitude, may be the cause of these variations.
Hence option A is correct.

If a 70 kg. skater acted upon by an unbalanced force of 161 N [West], what is
its acceleration?
According to Newtonʼs Second Law of Motion:
F net = m x a
or
a = F net / m
Acceleration = net Force/ Mass = 161 / 70 = 2.3 m/s^2 [W]
If a 70 kg skater is acted upon by an unbalanced force of 161 N [West], his acceleration would be 2.30 m/s² towards the west
What is Newton's second law?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
The mathematical expression for Newton's second law is as follows
F = m*a
where F represents the force applied
m is the mass of the object
a is the acceleration of the object
As given in the problem If a 70 kg. skater acted upon by an unbalanced force of 161 N
F =ma
By substituting the values of the force and the mass as 161 N and 70 kg respectively
161 N = 70×a
a= 2.30 m/s²
Thus, If a 70 kg skater is acted upon by an unbalanced force of 161 N, his acceleration would be 2.30 m/s² towards the west

an experimental plane, currently overhead, is flying at 120 mph at an altitude of 32 thousand feet. how fast is the plane’s distance from you increasing at the moment when the plane is flying over a point on the ground 24 thousand feet from you?
This question involves the concepts of Pythagora's Theorem and derivatives.
The plane's distance is increasing at a rate of "105.6 ft/" (OR) "72 mph".
First, we will write an expression for the distance between the person and the plane in terms of time. For that purpose, we will use Pythagora's Theorem. Here, the altitude will act as perpendicular, the horizontal distance on the ground will be the base, and the straight line distance between the plane and the person will be the hypotenuse.
[tex]Hyp^2 = Base^2+Perp^2\\s^2 = (vt)^2+(32000\ ft)^2\\s=\sqrt{(vt)^2+(32000)^2}[/tex]
where,
s = plane's distance from the person
v = horizontal speedof the plane = [tex](120\ mph)(\frac{1.47\ ft/s}{1\ mph})[/tex] = 176 ft/s
t = time
Therefore,
[tex]s=\sqrt{(176t)^2+(32000)^2}[/tex]
Taking the derivative with respect to time:
[tex]\\\\\frac{ds}{dt} = \frac{1}{2}\frac{(2t)(176)^2}{\sqrt{(176t)^2+(32000)^2}}\\\\\frac{ds}{dt} = \frac{61952\ t}{2s}[/tex]
where,
[tex]\frac{ds}{dt}[/tex] = rate at which plane's distance is increasing from the person = ?
s = distance = [tex]\sqrt{(24000\ ft)^2+(32000\ ft)^2} = 40000\ ft[/tex]
t = time = [tex]\frac{horizontal\ distance}{v} = \frac{24000\ ft}{176\ ft/s} = 136.36\ s[/tex]
Substituting these values in the equation, we get:
[tex]\frac{ds}{dt}=\frac{(61952)(136.36)}{(2)(40000)}[/tex]
[tex]\frac{ds}{dt}=105.6\ ft/s = 72\ mph[/tex]

Henry ran a 100 m race. Use the graph to answer the following:
a. How long did it take for Henry to run 100 m?
b. What is Henry's average speed over the race?
Using the graph, which describes how Henry ran the 100m race;
a) It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is; 5m/s.
According to the linear graph which describes the distance ran by Henry during the 100m race as a function of time.
a) Since the distance from start ran by Henry is plotted on the vertical axis, and the time is plotted on the horizontal axis;
To determine how long it took Henry to run 100m; The point corresponding to 100m is traced downward from the line of the graph and we find out that;
It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is simply;
The slope of the distance-time graph.
Therefore,
Average speed = (100-0)/(20-0)Average speed = 100/20Average speed = 5m/s.Therefore, Henry's average speed over the race is; 5m/s.

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.

Question 5 (1 point) true or false: Balanced forces acting on an object result in constant velocity True False
Answer:
false
Explanation:
By Newton's first law (An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force), neither speed nor direction change. Our force is balanced.
Balance forces could happen when the object is at rest but not all the time. A balance force is when a object is being push in opposite directions, which would cause the object to stay still or move at a constant speed. Which would mean that balance force could take place when a object is moving or when a object is at rest.

Blue bumper car, traveling east with a force of 100 N, runs into a yellow bumper car traveling west with a force of 300 N. Because the net force will be -200 N. one of the cars will be pushed backward. Which one?
Answer:
the blue bumper car
Explanation:
because the yellow bumper car is coming in with much more force
and according to Newton, actions and reactions are equal and opposite, so the yellow bumper car will five out 300N while the blue car will give out only 100N
then it almost because a fight between 300N vs 100N
and obviously, the 300N will win and the 100N will be pushed back
