A lever has an effort arm that is 8 meters long and the residence (load) arm that is 1.5 meters long, how much effort is needed

andrew11 [14]

Answer:

1066.67 N

Explanation:

Given that two measurements of the arm and an input weight. To answer this problem,we need to balance the forces and use the lengths of the arms.

Force × effort of arm distance= input weight × load distance

200 N * 8 m = x * 1.5 m

1600 = 1.5x

x = 1600/1.5

x = 1066.666 N

it takes 1066.67 N to lift the input weight

faust18 [17]

Answer:

The answer to this question is given below in the explanation section. However, the correct answer is C.

Explanation:

In pyton tutrle graphic library is used to draw lines and graphics. So, Madison should use the turtile python library to show the rise and fall of stock prices in visual presentation (lines).

Other options are not correct because Python use math module library for mathematical tasks, shape graphics library is used for drawing a graphic windows etc, while Video module library is used for video editing etc.

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, a

ANTONII [103]

Answer:

a) the average CPI for machine M1 = 1.6

the average CPI for machine M2 = 2.5

b) M1 implementation is faster.

c) the clock cycles required for both processors.52.6*10^6.

Explanation:

(a)

The average CPI for M1 = 0.6 x 1 + 0.3 x 2 + 0.1 x 4

= 1.6

The average CPI for M2 = 0.6 x 2 + 0.3 x 3 + 0.1 x 4

= 2.5

(b)

The average MIPS rate is calculated as: Clock Rate/ averageCPI x 10^6

Given 80MHz = 80 * 10^6

The average MIPS ratings for M1 = 80 x 10^6 / 1.6 x 10^6

= 50

Given 100MHz = 100 * 10^6

The average MIPS ratings for M2 = 100 x 10^6 / 2.5 x 10^6

= 40

Machine M2 has a smaller MIPS rating

Changing instruction set A from 2 to 1

The CPI will be increased to 1.9 (1*.6+3*.3+4*.1)

and hence MIPS Rating will now be (100/1.9)*10^6 = 52.6*10^6.

Which of the following is true of how packets are sent through the Internet?

astra-53 [7]

Answer:

It is A: Packet metadata is used to route and reassemble information travelling through the internet.

Explanation:

Step 1: The Internet works by chopping data into chunks called packets. Each packet then moves through the network in a series of hops. Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee

Step 2: Entering the network

Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee.

Step 3: Taking flight

The next hop delivers the packet to a long-haul provider, one of the airlines of cyberspace that quickly carrying data across the world.

Step 4: BGP

These providers use the Border Gateway Protocol to find a route across the many individual networks that together form the Internet.

Step 5: Finding a route

This journey often takes several more hops, which are plotted out one by one as the data packet moves across the Internet.

Step 6: Bad information

For the system to work properly, the BGP information shared among routers cannot contain lies or errors that might cause a packet to go off track – or get lost altogether.

Last step: Arrival

The final hop takes a packet to the recipient, which reassembles all of the packets into a coherent message. A separate message goes back through the network confirming successful delivery.
