The voltage on a resistor will be "12 V".

According to the given question,

Current,

I = 5.0 A

Power,

P = 60

As we know the formula,

→ $Power (P)= Current(I)\times Voltage (V)$

or,

→ $V = \frac{P}{I}$

By putting the giving values, we get

→ $= \frac{60}{5}$

→ $= 12 \ V$

Thus the solution above is right.

Explanation:

Applying Ohm's law, we have that the formula for power is a product of the current and voltage in the resistor.

$P = I \times V$

P = 60 W and I = 5.0 A

$60 = 5 \times V$

$V = 60 \div 5$

$V = 12 V$

Hope this helped!

Oxnard Casualty wants to ensure that their e-mail server has 99.98 percent reliability. They will use several independent server

sattari [20]

Answer:

The smallest number of servers required is 3 servers

Explanation:

Given

$Reliability = 99.98\%$

$Individual Servers = 95\%$

Required

Minimum number of servers needed

Let p represent the probability that a server is reliable and the probability that it wont be reliable be represented with q

Such that

$p = 95\%\\$

It should be noted that probabilities always add up to 1;

So,

$p + q = 1$ '

Subtract p from both sides

$p - p + q = 1 - p$

$q = 1 - p$

Substitute $p = 95\%\\$

$q = 1 - 95\%$

Convert % to fraction

$q = 1 - \frac{95}{100}$

Convert fraction to decimal

$q = 1 - 0.95$

$q = 0.05$

------------------------------------------------------------------------------------------------

To get an expression for one server

The probabilities of 1 servers having 99.98% reliability is as follows;

$p = 99.98\%$

Recall that probabilities always add up to 1;

So,

$p + q = 1$

Subtract q from both sides

$p + q - q = 1 - q$

$p = 1 - q$

So,

$p = 1 - q = 99.98\%$

$1 - q = 99.98\%$

Let the number of servers be represented with n

The above expression becomes

$1 - q^n = 99.98\%$

Convert percent to fraction

$1 - q^n = \frac{9998}{10000}$

Convert fraction to decimal

$1 - q^n = 0.9998$

Add $q^n$ to both sides

$1 - q^n + q^n= 0.9998 + q^n$

$1 = 0.9998 + q^n$

Subtract 0.9998 from both sides

$1 - 0.9998 = 0.9998 - 0.9998 + q^n$

$1 - 0.9998 = q^n$

$0.0002 = q^n$

Recall that $q = 0.05$

So, the expression becomes

$0.0002 = 0.05^n$

Take Log of both sides

$Log(0.0002) = Log(0.05^n)$

From laws of logarithm $Loga^b = bLoga$

So,

$Log(0.0002) = Log(0.05^n)$ becomes

$Log(0.0002) = nLog(0.05)$

Divide both sides by $Log0.05$

$\frac{Log(0.0002)}{Log(0.05)} = \frac{nLog(0.05)}{Log(0.05)}$

$\frac{Log(0.0002)}{Log(0.05)} = n$

$n = \frac{Log(0.0002)}{Log(0.05)}$

$n = \frac{-3.69897000434}{-1.30102999566}$

$n = 2.84310893421$

$n = 3 (Approximated)$

Hence, the smallest number of servers required is 3 servers

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binar

mylen [45]

Answer:

The program to this question can be described as follows:

Program:

num= int(input('Enter a number: ')) #input value by user

st = '' #defining string variable

while num > 0: #define loop to calculte values binary number

val= num % 2 # holding remainder (0 or 1) in val variable

st =st+str(val) # store value in str variable

num = num//2 #calculte quotient value

print("binary number is: ",st)

Output:

Enter a number: 5

binary number is: 101

Explanation:

Program description as follows:

Firstly the "num" variable is declared, for user input, then an "st" variable is declared, to calculates user input value binary number.

In the next step, a while loop is declared, inside the loop, another variable "Val" is declared, that holds value remainders, which is added on the "st" variable.

Outside the loop, the print method is used, that prints st variable holds value.

What is the faster way for browsers to obtain the revocation status of a digital certificate attached to a Web site?

Lyrx [107]

Answer:

The fastest way to obtain the revocation status of digital certificate of the website is by using Online certificate Status Protocol (OSCP).

Explanation:

Online certificate status protocol is the protocol that help user to check and verify the digital certificate revocation status. This protocol is linked with the digital certificate issuance authority. Whenever someone want to verify the status of the digital certificate that is attached to access the website. The website administrator can send the request to OSCP handler to ensure the status of the certificate. The OSCP handler is connected through certificate issuance authority, send the detail to verify the status. After verifying the status, OSCP handler respond as certificate is valid or revoked to the concerned user.
