What is the purpose of encryption?

1 answer:

5 0

Answer:

Encryption enhances the security of a message or file by scrambling the content. To encrypt a message, you need the right key, and you need the right key to decrypt it as well.It is the most effective way to hide communication via encoded information where the sender and the recipient hold the key to decipher data.

A jet impinges directly on to a plate that is oriented normal to the axis of the jet. The mass flow rate of the jet is 50 kg/min

PilotLPTM [1.2K]

Answer:

166.67 N

Explanation:

Given:

Mass flow rate = 50 kg/min = 50 kg / 60 seconds = 0.833 kg/s

Initial velocity = 200 m/s

after striking the normal board the water will flow in the normal direction, thus the final velocity in the direction of the initial flow will be zero

therefore,

Force = (change in momentum)

Force = Initial momentum - final momentum

Force = 0.833 × 200 - 0.833 × 0

Force = 166.67 N

Our goal is to design a traffic-light controller with the following properties; it lights up the green light (output G) for 15 s

nataly862011 [7]

Answer:

There will be three (3) states that will be needed in-order to implement the FSM controller.

Explanation:

FSM stands for Finite-State Machine. This is an example of a model used in mathematical computation. The FSM is an abstract machine that can be in exactly one of a finite number of states at any given time.

Ignoring any losses, estimate how much energy (in units of Btu) is required to raise the temperature of water in a 90-gallon hot

Rudik [331]

Answer:

Q=36444.11 Btu

Explanation:

Given that

Initial temperature = 60° F

Final temperature = 110° F

Specific heat of water = 0.999 Btu/lbm.R

Volume of water = 90 gallon

Mass = Volume x density

$1\ gallon = 0.13ft^3$

Mass ,m= 90 x 0.13 x 62.36 lbm

m=729.62 lbm

We know that sensible heat given as

Q= m Cp ΔT

Now by putting the values

Q= 729.62 x 0.999 x (110-60) Btu

Q=36444.11 Btu
