What is the magnitude of a the displacement vector for a woman who runs 915 m West and then turns and goes 681 m North.
Answer: 1141km
Explanation:
Given the following :
Distance due west = 915m
Distance due North = 681m
The magnitude of the Displacement =?
The information above produces a right angle triangle and the magnitude of the displacement can be calculated using Pythagoras rule :
The Magnitude of the woman's Displacement represents the hypotenuse of the triangle:
From Pythagoras :
Hypotenus = √(opposite)^2 + (adjacent)^2
Hypotenus = √(915)^2 + (681)^2
Hypotenuse = √1300986
Hypotenuse= 1140.6077
The magnitude of woman's displacement = 1140.6077 = 1141(to the nearest kilometer).

Use the information and model to answer the following question.
Echippus is an early ancestor to modern horses that lived 40 million years ago. The organism had a short neck, a short tail and feet with four toes. After ten million years, the tail and neck became longer and one of the toes disappeared as evidenced by the fossil of Mesohippus. Evolution of these organisms continued for 20 million years up to the present day causing the organisms to have longer necks and one solid hoof.
Answer:
D
Explanation:
The fossil record shows that the mammals gradually evolved so that their toes became one large hoof so this variation must have been more useful for survival than many toes. The correct option is 1.
What is fossil record?Paleontologists, archaeologists, and geologists use the fossil record to place important events and species in the correct geologic era.
It is based on the Law of Superposition, which states that the bottom layers in undisturbed rock sequences are older than the top layers.
The neck and toes of early horse ancestors evolved in such a way that the neck and tail became longer and one of the toes disappeared over time. The fossil record demonstrates this, as Echippus had a short neck, a short tail, and four-toed feet.
The fossil record shows that mammals gradually evolved their toes into one large hoof, implying that this variation was more useful for survival than many toes.
Thus, the correct option is 1.

A student builds a series circuit using three 1-ohm resistors. The current in the circuit is 1.5 amps. What is the voltage drop across each resistor?
(no explanation is needed! i just need the answer)
ANSWER:
Charge flows together through the external circuit at a rate that is everywhere the same. The current is no greater at one location as it is at another location. The actual amount of current varies inversely with the amount of overall resistance. There is a clear relationship between the resistance of the individual resistors and the overall resistance of the collection of resistors. As far as the battery that is pumping the charge is concerned, the presence of two 6-Ω ;resistors in series would be equivalent to having one 12-Ω resistor in the circuit. The presence of three 6-Ω resistors in series would be equivalent to having one 18-Ω resistor in the circuit. And the presence of four 6-Ω resistors in series would be equivalent to having one 24-Ω resistor in the circuit.

Which part of the following excerpt from an after-action report is inappropriate to include?
Our goal was to make the Fierce Dragon a more exciting and desirable toy for older children. To meet this goal, we chose to increase the number of working parts and to make the face appear angrier. Even though there were several disputes during our meetings, a 25-percent increase of sales in the target age group over the past three months indicates we met our goal. The initial response to the redesigned toy was very positive; however, the number of returns due to a broken jaw joint indicates more testing of the design should have been done.

in short easy answer pls!
Answer:
Air always moves from high-pressure places to low-pressure places. This means air moves from denser air to less dense air. This movement of air results in wind. If, for example, there was an area of high-pressure air east of an area of low-pressure air, then the wind would be coming in from the east.

A skydiver dives from an airplane. Air resistance is measured each second following the skydiver’s jump. Which statement BEST identifies the skydiver’s speed at each second?
PLS HELP QUICK
Answer: (B) 4 Seconds
Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)
Answer : B. The sjydriver has the fastest speed at 4second.
What is air resistances ?
--Air resistance is a type of friction force.
-- Air resistance, there are not two solid surfaces in contact.
-- Air resistance is the frictional force acting on an object and the air around them.
--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.
Concept Used
-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.
-- A person’s weight force will always stay the same.
-- The weight force of the person will equal their air resistance.
-- This would make the skydiver travel at constant speed.
--To travel at constant speed forces have to be equal to zero.
--This constant speed is called terminal velocity

The air currents across the continents would determine the distribution of the air.
What are air currents?Air currents across the continents are primarily driven by temperature differences and the rotation of the Earth. The warm air near the equator rises and flows towards the poles, while the cooler air near the poles sinks and flows towards the equator.
This creates large-scale circulation patterns known as Hadley cells, Ferrell cells, and Polar cells. These cells are responsible for the trade winds, westerlies, and easterlies, respectively. Additionally, there are also local winds caused by differences in terrain, such as sea breezes and valley breezes.
