Answer:

Friction produces unnecessary heat leading to the wastage of energy.

The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.

It causes wear and tear of machines.

A lot of money goes into preventing friction and the usual wear and tear caused by it by using techniques like greasing and oiling.
It always resists the motion, so extra energy is required to overcome it.
It decreases the life expectancy of moving parts of vehicles.

A car speeds up from 3 m/s to 10 m/s in 8 s. How far does the car travel while doing this? 2. A

yarga [219]

Initial velocity=u=3m/s

Final velocity=v=10m/s

Time=t=8s

$\boxed{\sf Acceleration=\dfrac{v-u}{t}}$

$\\ \sf\longmapsto Acceleration=\dfrac{10-3}{8}$

$\\ \sf\longmapsto Acceleration=\dfrac{7}{8}$

$\\ \sf\longmapsto Acceleration=0.8m/s^2$

Distance =s

Using second equation of motion

$\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2$

$\\ \sf\longmapsto s=3(8)+\dfrac{1}{2}(0.8)(8)^2$

$\\ \sf\longmapsto s=24+0.4(64)$

$\\ \sf\longmapsto s=24+25.6$

$\\ \sf\longmapsto s=49.6m$

Suppose your network is connected to another network via a router. Which OSI model layer provides the information necessary to d

RUDIKE [14]

Answer: it is called the "NETWORK LAYER"

Explanation: OSI model means Open System Interconnection model. It have different model layers.

The network layer is the OSI model layer that helps in forwarding packets from network to network, using a network router. It's main function is to connect different network together. It also determine the best virtual circuits(paths) for the data to travel.

Because the question specify that the network is connected to a network router, that means the OSI model layer is network layer.
