Since momentum equals mass times velocity, if the mass of the truck times its velocity is greater than the mass of the bus times the bus' velocity then the momentum of the truck will be greater than the momentum of the bus.
because the bus still moving its uniform motion suddenly the bus applies brakes the bus stop at rest so we fall forward due to inertia and the bus was its rest suddenly the bus starts its accelerates so we fall backwards due to inertia
Modern processors have two bus types: the front-side bus and the back-side bus. The back-side bus is where your cache memory lives. Cache is a very small amount of very fast memory--just a couple of megabytes. It's on a separate bus because if the CPU was making cache requests along the same bus as it was making main-memory requests, it would slow the cache down so much that having it would be pointless. It's as small as it is because (1) it's expensive as hell, (2) it generates a lot of heat, and (3) nowadays, they put a lot of it in the processor itself and they don't want the processor to be the size of a Buick. The front-side bus is where your main memory lives. (This is also the bus the computer uses to talk to the video card, hard drive, modem and all the other things your computer is running, but that's not important now.) You know when you look at a computer ad, it says "This computer has 512MB RAM!" That's main memory. It's sitting on the front-side bus. And the faster that bus runs (it hasn't run at processor speed in decades) the faster your memory calls run and the faster your computer goes. Fast is good. The bus is rated in megahertz, same as your computer used to be before they started selling GHz PCs, and 800MHz is a very fast one.
Relative to the bus, you are moving towards the back. If your walking speed is slower than the speed of the moving bus (which it usually will be) then your motion relative to a point on the ground will be moving in the direction of the moving bus, but slower by the speed at which you are walking.
The bus has more momentum. Momentum is velocity times mass, if both vehicles are travelling at the same speed then they have the same velocity, but the bus full of people will have more mass. Therefore the mass component of the bus in the equation will be higher than that of the car, giving a higher overall momentum.
Either bus topology or star toplogy.
bus topology.
The "star" topology is the most common.
Bus topology LANs are very rare these days. It would be easier to use a star topology than a bus topology for a few devices.
Ring Topology, Mesh Topology, Bus Topology, Star Topology
star topology,bus topology,ring topology,mesh topology etc...
The most common LAN topology is that of a "star." In a star topology, each computer, or "node", is connected to a central hub. This is more reliable than a more classical "ring" topology, because a node failing will not bring down the entire network. A bus topology is arguably more reliable, but has poorer performance.
A star-wired bus is a hybrid topology (more than 1 type of topology). There is no particular access method that requires or relies on that type of hybrid.
