The term “parallax” refers to the apparent movement of objects when viewed from different positions. The everyday example of this is seen driving on the highway– when you look out the window, electrical poles near the road seem to zoom past, while trees in the distance appear to slowly drift by.

Why do stellar parallax measurements work only with relatively nearby stars? Parallax measurements work by measuring the relative change in position of stars as the earth goes around the sun. Apparent Magnitude is the star’s brightness as it appears from earth.

The Parallax Angle — How Astronomers Use Angular Measurement to Compute Distances in Space. The parallax angle is the angle between the Earth at one time of year, and the Earth six months later, as measured from a nearby star. Astronomers use this angle to find the distance from the Earth to that star.

Measuring large Distances. Measuring large Distances – Parallax Method. Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.

Due to foreshortening, nearby objects show a larger parallax than farther objects when observed from different positions, so parallax can be used to determine distances. To measure large distances, such as the distance of a planet or a star from Earth, astronomers use the principle of parallax.

Parallax is a deceptive change of the position of an object which is observed while the position of the observer changes. Position of eye at all volumetric vessels must be at the same level as the meniscus. If not, the parallax will cause an error while reading the position of the meniscus of a liquid in a burette.

Here is a clever method to estimate how far away something is:

1. Hold your arm straight out, thumb up.
2. Close one eye, align your thumb with distant object.
3. Switch eyes (don’t move your thumb!)
4. Your thumb will seem to change position.

Maintaining a minimum following distance from the vehicle ahead of you of 6 seconds is a good rule of thumb for professional drivers. In order to figure your safe following distance, use a stationary object along the road in front of you and count the number of seconds that it takes to reach that object.

Bigger cars are harder to drive in congested traffic. That is because you can’t easily maneuver from one lane to the other because of the bigger size. Therefore, most likely, you will be one of those drivers that will be stuck in traffic.

When on a dual-carriageway, judge the speed of the car in front of you, and keep an eye out for vehicles in the adjoining lane or those approaching from behind. If the way is clear, pull out from the lane and make your move. It’s advisable to drop down a gear, as it will aid in acceleration.

A “blind spot” is an area alongside your vehicle that you can’t see when using any of your mirrors. It’s important to check these blind spots to ensure your side gates are open, particularly if you are going to change lanes.

Is driving a car hard? A. Driving a car can be as easy as running or walking once you get comfortable behind the wheel. For this, you need to practice hard, keep in mind all the rules and traffic laws and familiarize yourself well with the vehicle.

Regardless of the driving scenario, Brian Wind, PhD, a clinical psychologist at JourneyPure, says most often, people are afraid to drive because they fear something negative will happen. Moreover, this intense fear is often more significant and debilitating than the fear or worry caused by general stress or anxiety.

Motorcycles are categorically more difficult to operate than cars. You aren’t going to learn to drive a car overnight, and you certainly aren’t going to learn to ride a motorcycle without years of practice. Your dad is teaching you to drive.

So over a course with a series of corners, a car can be faster than a motorcycle. “Also on tight roads, a bike is a smaller percentage of the road so it can manoeuvre through the same sequence of bends faster as the bike doesn’t need to do as tight a corner radius so the difference is reduced.”

But if you are the type that rides carefully and in a safe way, motorcycle riding is very worth the risk because there are chances that you won’t make a life-threatening accident. But with all that, most motorcyclists stay healthy and intact and don’t make a life-threatening accident.

A car is more comfortable, has AC, and you can listen to your favorite sounds or talk on the phone. Bike ride, hands down, although I don’t think you will get many people who use both modes (except for those that never ride a bike on the road) that would pick the car.

Bike commuting helps society in a number of ways. It’s less wear and tear on the public roads, less pollution in the air, less traffic and congestion for other cars, allows more parking spots, and is less noisy through neighborhoods.

If anybody is planning on a road trip with friends or family, then CAR is the best option as more people can travel together. Car is more spacious so if required one can put some of their stuff in it easily. Therefore, it is more safe & comfortable travelling in a car than a bike for longer routes.

2) Lesser Traffic Congestion – A bike can squeeze through traffic easily which makes it easy to avoid jams, helping you to reach your destination quickly. 5) Affordability – Not only are bikes cheaper than cars but they also offer better performance while also being lighter on the pocket to run.
