Ines of latitude run from _______________ and measure angular distances ___________ of the equator.
Ines of latitude run from East to West and measure angular distances North or South of the equator.
The latitude defines a geographical coordinate of a location on the earth's surface and is the angular distance of that point (north or south of the equator) measured with respect to the Earth's Center. It is zero at the equator and 90 degrees at the poles. Latitude lines, often known as parallels, are imaginary lines that divide the Earth. They go east to west, although you may measure north or south. The most well-known parallel is the equator. It splits the Earth into Northern and Southern hemispheres at 0 degrees latitude.

A car of weight 3,217 lb is traveling in a straight line at a speed of 60 ft/s. how much force does it require to stop the car in 5 seconds? assume that the gravitational acceleration is 32.17 ft/s2.
Answer:
in this problem, we have given a card of wait. £3217 is traveling in a straight line at a speed of 60 ft/s. How much force does it require to stop the car in five seconds. So here we will use a cinematic equation. We finally, is it caused to the initial plus acceleration in two times. So finally, spirit will be zero initially 60 ft/s and exhalation. We have to find And time is five seconds. Right? So we need acceleration, Which is a cost to -60 x five. That is a cost to 12 feet per second square. That means we need acceleration in the opposite direction, so we need a force which is in the opposing direction of the motion. So this force, if we talk about the magnitude, there should be equal to mass into acceleration. So this mass of card will be weight divided by G, into exploration. That is 12 serve it of cars, and 3217, And G is 32.17 in 212. So this force in pounds is equal to £1200 in the opposite direction of motion.
Explanation:
The force required to stop the car is 5334.09 Newtons. The force is negative representing the deceleration.
The car's weight to mass:
Weight = 3,217 lb
1 lb = 0.453592 kg
Mass = Weight ÷ gravitational acceleration
Mass = 3217 × 0.453592
Mass = 1459.59 kg
The initial velocity is:
Initial velocity = 60 × 0.3048
Initial velocity = 18.288 m/s
Since the car stops, the final velocity will be 0 m/s.
The acceleration is:
Acceleration = (Final velocity - Initial velocity) ÷ time
Acceleration = -3.6576 m/s²
The force required to stop the car using Newton's second law of motion:
Force = m × a
Force = 1459.59 × (-3.6576)
Force = -5334.09 N
Therefore, The force required to stop the car is 5334.09 Newtons. The force is negative representing the deceleration.

For customer arrivals, the random number interval assigned to the time between arrivals of 2 minutes is 0.0500-0.19999.
What do you mean by time?Time is the continued sequence of the existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of the various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with the three spatial dimensions.
Time has long been an important subject of the study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as the business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.
Time in physics is operationally defined as the "what a clock reads".
The physical nature of the time is addressed by general relativity with respect to events in spacetime. Examples of events are collision of two particles, the explosion of a supernova, or the arrival of a rocket ship. Every event can be assigned the four numbers representing its time and position (the event's coordinates).
However, the numerical values are different for the different observers. In general relativity, question of what time it is now only has meaning relative to a particular observer. Distance and the time are intimately related, and the time required for light to travel a specific distance is the same for all observers, as first publicly demonstrated by Michelson and Morley. General relativity does not address nature of time for extremely small intervals where quantum mechanics holds. At this time, there is no generally accepted theory of the quantum general relativity.

It doesn’t matter whether you move the coil while keeping the magnet fixed or the other way around if you want to change the surface area of the loop (raise by expanding the loop, decrease by reducing the loop).
The way they move in respect to one another determines how the magnetic flux across the coil changes.

How long would it take?We know that speed is expressed as the ratio of distance to time. In this case, we are trying to know ow many years would it take to reach the planet Saturn travelling at 21 thousand miles per hour.
Given that;
Speed = 21 thousand miles per hour
time taken = ???
Distance = 887 million miles
Speed = distance/time
speed * time = distance
time = distance/speed
time = 8.87 * 10^8 miles/2.1 * 10^4 miles per hour
time = 4.22 * 10^4 hours
If 8.766 * 10^3 hours make 1 year
4.22 * 10^4 hours make 4.22 * 10^4 hours * 1 year/8.766 * 10^3
= 4.8 years

If you exert a force f on an object which has a much greater mass than you do, the force which the object exerts on you will?
If you exert force on an inanimate item, you will also be able to calculate the force that the object will apply to you, which will be opposing and equal to your own.
What would happen if you applied a force that was smaller than the object's mass?In order to accelerate a heavier (more massive) item in motion, more force must be exerted. When two objects are subjected to the same force, the smaller mass item will change speeds more quickly.
An item can alter its size or shape, begin moving, stop moving, accelerate, or decelerate as a result of a force acting on it. When two things contact, they exert pressures on one another that are identical in size but directed in the opposite direction
The action-reaction law is another name for this rule.
When just one body decides the strength and direction of the force, the force that body exerts is referred to as the "action," and the force that the other body exerts in a similar but opposite direction is referred to as the "reaction."

How is radioactive decay used to date sedimentary rocks?
a) the amounts of potassium and argon in sedimentary rocks are measured.
b) the amounts of carbon-14 and nitrogen in sedimentary rocks are measured.
The correct option is (d) It is measured how many unstable elements are present in the volcanic layers above and below the sedimentary layers.
How is radioactive decay used to date sedimentary?
Researchers use some kind of clock to ascertain the date when a rock or fossil was generated in order to calculate its age. In order to reliably date historic events, geologists frequently utilize radiometric dating techniques, which are based on the natural radioactive decay of specific elements like potassium and carbon.
Natural radioactive decay results from the atomic nucleus becoming unstable and releasing fragments. Radioactive particles are released as a result (there are many types). When the number of protons and neutrons in the nucleus is balanced as a result of this decay process, the atom becomes stable.

The body process in which an adequate supply of oxygen converts glucose into energy is called:________
Aerobic metabolism can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell.
What is Cellular respiration ?Through the process of cellular respiration, organisms mix oxygen with food molecules, directing the chemical energy contained in these substances toward life-sustaining processes while excreting carbon dioxide and water as waste.
Glycolysis, also known as the citric acid cycle, is the first stage of cellular respiration. The Krebs cycle, also known as the electron transport chain, is the second stage Anaerobic and aerobic respiration are the two basic forms of cellular respiration. It need oxygen (O2) to make ATP during an exclusive type of cellular respiration known as aerobic respiration.Learn more about Cellular respiration here:

A wheel rotates with 1800rpm. A)Find the revolutions per minute. B)what is the angular speed of the wheel in rad/s. Use =3
Answer:
Option C
Explanation:
Initial frequency of rotation ν
i
=1800 rpm =1800/60=30 rps
Thus initial angular frequency w
i
=2πν
i
=60π rad/s
Final frequency of rotation ν
