A larger object requires more energy to generate velocity. And since you can't lose energy due to the law of conservation of mass, inertia ( an objects resistance in its change of state whether increasing or decreasing in energy) makes it so all that energy that was used to propel the large object needs to be absorbed.

To sum up,
larger objects require more time to stop than small objects because of how much more energy is needed to move them.

What isthe concept of packets, give example?

Oduvanchick [21]

Answer: Packets are the small unit of data that is sent from source to destination on a network.

Explanation: Packets are small packages that carry data in a packet form and is used from transferring it on internet or any kind of packet-switched network. They use the internet protocol (IP) for the transmission of data.

Example: packet radio is a sort of digital radio that uses the packet for transmission of data to other nodes by utilizing the AX-25 protocol.

The listing of a directory shows certain files with permissions set to rwsr-xr-x. what does this indicate?

marta [7]

<span>"rws" means that the user has permissions to read, write and setuid. "r" means the user can read the file and "w" means that the user can write to the file. "s" stands for "setuid" (set user id) is a permission bit that allows the users to execute a program with the permissions of its owner. The "s" can also mean "setgid" (set group id) is a bit that allows the user to execute a program with the permissions of the group owner.</span>

Which statement is NOT true:

RSB [31]

Answer:

The correct answer for the given question is "Machine languages can be used to write programs that can run on any machine."

Explanation:

The machine language consist of binary digit i. e 0 and 1 .Computer can understand only the machine language .The machine language consist of code that is written in bits so it is used to express algorithms.When any program is compiled the compiler are converted into machine code so the machine language is produced by the compiler .

Machine language cannot used to write a program that run on any machine.

Convert the following numbers. (Please show all steps; no marks will be awarded if no steps are shown) [1.5 x 4 = 6 marks]

katen-ka-za [31]

Answer:

i. 10210212

ii. 100 101 001 in BASE 2

iii. 46.4631

iv. 12.453125

Explanation:

i. Converting to base 10 we get

= 10 x 162 + 13 x 161 + 9 x 160 = 2777

Converting to base 10 we get =

2777/3 = 925 with remainder 2

925/3 = 308 with remainder 1

308/3 = 102 with remainder 2

102/3 = 34 with remainder 0

34/3 = 11 with remainder 1

11/3 = 3 with remainder 2

3/3 = 1 with remainder 0

1/3 = 0 with remainder 1

Hence the Answer is 10210212

ii. = Octal is taken in pair of 3 bits , Writing binary of each number in 3 bits we get = 100 101 001 in BASE 2

iii. = 1 x 52 + 2 x 51 + 3 x 50 + 3 x 5-1 = 38.6 in decimal

Converting to Octal we get

38 /8 = 4 with remainder 6

4 /8 = 0 with remainder 4

.6 x 8 = 4.8

.8 x 8 = 6.4

46.4631

iv. = 1x 81 + 4 x 80 + 3 x 8-1 + 5 x 8-2 = 12.453125
