"Hint: A backslash \ in a string acts as an escape character, such as with a newline \n. So, to print an actual backslash, escap

Tcecarenko [31]

Answer:

True

Explanation:

The \ is an escape character, is a way to indicate to the compiler that the following characters are special; if you want to print an actual \ you need to use two, one after the other one, in the printf function. But what exactly happens if you try to print just one \

#include <iostream>

using namespace std;

int main()

{

printf ("\");

}

This will produce an error that prevents you from compiling:

main.cpp:15:13: warning: missing terminating " character

printf ("\");

Refer to the following distribution of commissions:Monthly Commissions Class Frequencies$600 up to $800 3800 up to 1,000 71,000

erica [24]

Answer:

21.81 %

Explanation:

given,

$600 up to $800 3

800 up to 1,000 7

$1,000 up to $1,200 11

$1,200 up to $1,400 12

$1,400 up to $1,600 40

$1,600 up to $1,800 24

$1,800 up to $2,000 9

$2,000 up to $2,200 4

Total = 3 + 7 + 11 + 12 + 40 + 24 + 9 + 4 = 110

the frequency of $1,600 to $1800

= $\dfrac{24}{110}$

=21.81 %

A 50 Ibm block is moving at 4 ft/s. Find Its total kinetic energy? Also find Its kinetic energy per unit mass is

Kamila [148]

Answer:

Total kinetic energy= 400 puondal foot

Kinetic energy per unit mass= 8 (poundaul foot/lb)

Explanation:

To determine the total kinetic energy of the block we use the equation:

Kinetic energy = (1/2) × m × (v^{2}) = (1/2) × (50lb) × (4 foot/s)^{2}) =

= 400 poundal foot

To establish the kinetic energy per unit of mass we must simply divide the value of the total kinetic energy obtained previously by the mass of the block obtaining:

Kinetic energy per unit mass= (400 poundal foot) / (50lb) =

= 8 (poundaul foot/lb)

Air is compressed steadily from 100kPa and 20oC to 1MPa by an adiabatic compressor. If the mass flow rate of the air is 1kg/s an

igomit [66]

Answer:

(a). 575 kJ/kg.

(b). 290kw.

Explanation:

We have the following set of information or parameters from the question above;

Pressure(1) = 100kPa, Pressure (2) = 1MPa, temperature(1) = b1= 12°C = 285K = 285kJ/kg, efficiency = 80% and the mass flow rate of the air = 1kg/s.

At a temperature of 12°C, we have the value from steam table; gx= 1.2, thus gx22 = 1.2 × (1000/100) = 12.

We have that the value for b12 = 517.

Therefore, the value for h2a can be calculated as;

80/100 = (517 - 285)/ (tp at exist) - 285.

0.8 = 232/ (tp at exist) - 285.

232 = 0.8 × (tp at exist) - 285).

232 = 0.8 (tp at exist) - 228 .

(tp at exist) = 575.

Therefore, the temperature 575 kJ/kg.

Thus, the required power input of the compressor = 1kg/s × ( 575 - 285) = 290kw.
