A bus (contracted from omnibus, with variants multibus, motorbus, autobus, etc.) is a road vehicle designed to carry many passengers. Buses can have a capacity as high as 300 passengers. The most common type is the single-deck rigid bus, with larger loads carried by double-decker and articulated buses, and smaller loads carried by midibuses and minibuses while coaches are used for longer-distance services. Many types of buses, such as city transit buses and inter-city coaches, charge a fare. Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus do not charge a fare. In many jurisdictions, bus drivers require a special licence above and beyond a regular driving licence.
Buses may be used for scheduled bus transport, scheduled coach transport, school transport, private hire, or tourism; promotional buses may be used for political campaigns and others are privately operated for a wide range of purposes, including rock and pop band tour vehicles.
Horse-drawn buses were used from the 1820s, followed by steam buses in the 1830s, and electric trolleybuses in 1882. The first internal combustion engine buses, or motor buses, were used in 1895. Recently, interest has been growing in hybrid electric buses, fuel cell buses, and electric buses, as well as buses powered by compressed natural gas or biodiesel. As of the 2010s, bus manufacturing is increasingly globalised, with the same designs appearing around the world.
It's rush hour, you are heading home, and your bus is suck in traffic. It is moving 2 m/s. you get frustrated and decide to walk towards the front of the bus at 4 m/s. What is your new velocity relative to the ground?
a. what is your velocity relative to the bus?
b. what if you decided to...
I know for a fact that whenever I am standing on the platform of a bus that starts accelerating from zero I have a tendency to go backwards. The friction on my shoes prevent from going backwards of course and I do the slightest stumble.
However, what causes the body in an accelerating bus to...
So I was taking the bus the other day and i started thinking about this.
If you're standing in a bus, and the bus starts to move, you'll stumble forward if you're not creating enough force opposite the direction of the bus' movement. So why does this happen? This is my theory: The static...
i saw a hindi movie that had an end scene with a bus with a few passengers involved in a mishap and end up hanging out of a cliff.
the hero tells everyone to move the frnt slowly ... which made sense - in the end there is an old couple at the back and the ladys frozen with fear.
so he asks...
I have noticed, that a graph of ingenuity as a function of the distance from the front of a bus full of seniors on their 3-day field trip to Eilat, behaves in the following pattern: The graph Starts out at relatively low (the driver is never too bright) and climbs in a parabolic fashion to reach...
Hello All,
I have a circuit that uses a microcontroller to communicate via a three-wire serial line (SPI) to a DDS chip to send and receive commands and status information. My question is that if the DDS IC happens to be on a different board and I want to galvanically isolate them from each...

I've set up RAM on a bus such that one chip takes the lower nibble and another chip takes the upper nibble of a particular data value at a specific address. Both chips are given the same address, but each one contains only half of the data. I want to call this interleaving, but I'm not sure if...
I have read forums that talk against US suburbs and often blame the car for urban sprawl. Now, isn't there a really very simple solution to this ? Just create a well thought out public (or even private companies) transportation system throughout all the US suburbs, maybe using various sized...
I need to take a 16-bit parallel digital input and transfer it to an 8-bit bus. I'm able to capture the 16-bit input by splitting the input and sending one through an ALS373 tri-state latch and the other half through 2 ALS373's, but I'm having problems with the bus interface.

The answer key says that the answer is the bus coming to a stop. I think this is the answer because the wheels of the bus are slowing down. Is this the...

A pedestrian is running at his maximum speed of 6.0 m/s to catch a bus stopped by a traffic light. When he is 25 meters from the bus, the light changes and the bus accelerates uniformly at 1.0 m/s2. Find either {A} how far he has to run to catch the bus or {B} his frustration distance (closest...

this was one question I've always thought upon right from the time i have learned abt forces and velocity .. a bus movin with a uniform velocity has zero acceleration ... then how, in such a case does a person get injure or even die when a bus collides with him ?? if the bus is...
I've been looking at system architectures, and it seems almost always, a specific device on the memory bus uses a staggered type of addressing. What I mean by this is that say you have a chip select exclusive to 1 device. The address bus may have lines A[25:0], but instead of matching each...

The acceleration of a bus is given by a (t)= alpha t, where alpha = 1.13 m/s^3 is a constant.
Part A) If the bus's velocity at time t_1 = 1.01 s is 4.93 m/s, what is its velocity at time t_2 = 2.15 s?
Part B) If the bus's position at time t_1 = 1.01 s is 6.01 m, what...
