When is the Earth at its maximum distance from the Sun?
At it point of aphelion in its elliptical orbit Round the Sun. This happens on the 4th of July each year. At this moment the Sun - Earth distance is 152,102,196 kilometers.
Why is it necessary to mention the axis of rectangular bar while calculating the moment of inertia?
An object rotating about its long axis will have a different moment of inertia than when it is rotating about its short axis. A solid disk will have a different moment than a washer, and there are formulas derived for calculating the moments of many common shapes.
How many minutes does it take for a radio message to reach earth from Saturn is 7.9 times 10 to eight?
The closest Saturn can be to earth is at the moment when both planets are lined upon the same side of the sun. Then, the distance is 797.8 million miles. Light and radiotake 71.4 minutes to cover that distance.The farthest Saturn can be from earth is at the moment when both planets are lined upon opposite sides of the sun. Then, the distance is 983.8 million miles. Light and radiotake 88 minutes to cover that distance.
Why can dipole moment be determined only for neutral system of charges not for charged one?
Dipole moment is calculated for a system with equal and opposite charges because this results in a net dipole moment, which is a measure of the separation of charge within the system. For a charged system, there is no overall separation of charge, so there would not be a net dipole moment to measure.
Does the speed limit sign refer to average or instantaneous speed?
Probably determined by the method used for enforcement. It refers to the speed you are going when the radar gun pings you (instantaneous speed) or the time it takes to cover a predetermined distance from an aircraft (average speed).The above refers to enforcement, as indicated. And it is correct. As regards enforcement. The to the question is that the speed limit sign refers to the maximum instantaneous speed at any point in your travels on a roadway that is so marked.
Is the element of total stopping distance called?
The element of total stopping distance is called reaction distance. It is the distance a vehicle travels from the moment a driver perceives a hazard until the moment they physically react by applying the brakes.
What is a element of total stopping distance?
One element of total stopping distance is the perception-reaction distance, which is the distance a vehicle travels from the moment a driver perceives a hazard until they physically react by applying the brakes.
What si an element Of total stopping distance?
An element of total stopping distance is the reaction distance, which is the distance your vehicle travels from the moment you see a hazard until you physically apply the brakes. This, combined with the braking distance (the distance your vehicle travels once the brakes are applied until it comes to a complete stop), makes up the total stopping distance.
What things affect your thinking distance?
Factors that can affect your thinking distance while driving include your reaction time, distractions, fatigue, alcohol or drug use, and road conditions. Thinking distance refers to the distance your vehicle travels from the moment you perceive a hazard to the moment you apply the brakes.
What is the distance your vehicle travels while stopping?
The distance your vehicle travels while stopping, known as the stopping distance, is the sum of the reaction distance and the braking distance. The reaction distance is the distance your vehicle travels from the moment you perceive a hazard until you physically hit the brakes. The braking distance is the distance your vehicle travels once the brakes are applied until the vehicle comes to a complete stop. Factors such as speed, road conditions, and vehicle condition can all affect the overall stopping distance.
What is meant by the term thinking distance?
Thinking distance refers to the distance a vehicle travels from the moment a driver perceives a hazard until they physically react, such as by braking. It is influenced by factors like reaction time and speed. A longer thinking distance can increase the overall stopping distance of a vehicle.
What is an element of total stopping distance?
An element of total stopping distance is perception distance, which is the distance a vehicle travels from the moment a driver detects a hazard to when they start applying the brakes. Other elements include reaction distance (distance traveled while the driver reacts) and braking distance (distance traveled after applying the brakes).
What is thinking distance affected by?
Thinking distance is affected by factors such as speed, reaction time, distraction, and the driver's state of mind. It represents the distance a vehicle travels from the moment a driver perceives a hazard until the driver reacts by applying the brakes. The faster the speed and longer the reaction time, the greater the thinking distance.
What is a reaction distance?
Reaction distance is the distance a vehicle travels from the moment a driver perceives a hazard until they physically react by applying the brakes or taking other evasive action. It is influenced by factors such as speed, driver alertness, and road conditions.
What is Perception distance plus reaction distance plus braking distance is called?
Perception distance plus reaction distance plus braking distance is called total stopping distance. It represents the total distance a vehicle will travel from the moment a driver recognizes a hazard until the vehicle comes to a complete stop.
What is the distance a vehicle travels from the moment an event occurs until you see it and become aware of the danger.?
If you experience brake failure while driving you should turn off the engine and coast to a complete stop?
Is the distance a vehicle travels from the moment an event occurs until you see it an become aware of the danger?
