7 0

Answer:

Induced current is 0.226 A

Explanation:

To calculate potential difference we have

E =1/2Bomega*r2 =1/2*1*1800*3.14*0.05=141.3

putting values we get

the p.d is 141.3

Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600 MHz. Computer B has a CPI of 2.5 and can be run at a
kirill115 [55]

Answer:

Check the explanation

Explanation:

CPI means Clock cycle per Instruction

given Clock rate 600 MHz then clock time is Cー 1.67nSec clockrate 600M

Execution time is given by following Formula.

Execution Time(CPU time) = CPI*Instruction Count * clock time = \frac{CPI*Instruction Count}{ClockRate}

a)

for system A CPU time is 1.3 * 100, 000 600 106

= 216.67 micro sec.

b)

for system B CPU time is =\frac{2.5*100,000}{750*10^6}

= 333.33 micro sec

c) Since the system B is slower than system A, So the system A executes the given program in less time

Hence take CPU execution time of system B as CPU time of System A.

therefore

216.67 micro = =\frac{2.5*Instruction}{750*10^6}

Instructions = 216.67*750/2.5

= 65001

hence 65001 instruction are needed for executing program By system B. to complete the program as fast as system A

There exists a data type Date with member function Increment that increments the current Date object by one. The ++ operator is
nalin [4]

Answer:

Date Date::operator++( int )

{

Date temp = *this;

Increment();

return temp;

}

Explanation:

Of options 1 through 4, only option 4 correctly implement the post increment of the ++ operator.

Interpreting each line of option for and comparing it to other options

Line 1: Date Date::operator++( int )

This declares the data type and its ++ operator

This is same for all options

Line 2: The Date type needs to be declared

In option 4, it was declared correctly as Date temp = *this;  using a pointer variable *this.

Here, option 2 is removed from the list of possible options.

Comparing other options

Line 3: The member increment option needs to be declared after the declaration of the date type variable.

This is correctly declared as Increment();  in option 4

Here, option 3 is removed from the list of possible options.

Comparing other options

Line 4: The value declared variable temp needs to be returned the way it was declared (without pointer indicator)

Hence, option 4 is best appropriate
