A solid weighs 20gf in air and 18gf in water .find the specific gravity of the solid

swat32

<h2>Answer:</h2>

10

<h2>Explanation:</h2>

Specific gravity (also called relative density) is the ratio of the density of an object (or substance) to the density of a reference substance (mostly water). It has no unit and is given by the following;

Specific gravity = $\frac{density-of-object}{density-of-water}$

Specific gravity is also given by the ratio of the weight of the object in air to the loss of weight of the object in water. i.e

Specific gravity = $\frac{weight-of-object-in-air}{loss-of-weight-in-water}$ --------------(* * *)

In this case;

i. The object is the solid which has a weight of 20gf in air.

ii. The loss of weight of the solid in water is the difference between the weight in air (20gf) and the weight in water (18gf).

Therefore the loss of weight is

20gf - 18gf = 2gf

Now substitute these values from (i) and (ii) into equation (* * *) as follows;

Specific gravity = $\frac{20gf}{2gf}$

Specific gravity = 10

Therefore the specific gravity of the solid is 10

Each of the following code fragments contains a number of security vulnerabilities. For each fragment, identify these security v

Trava [24]

Answer:

Check the explanation

Explanation:

a)

1) int main(int argc, char *argv){

argv has always been an array of pointer whereby each and every element points to the command line argument that is passed to the program.

int main(int argc, char *argv[]) {

2) passwords = fopen(filePath, "r");

argv[0] always holds the name of the program currently running i.e. itself

So you shouldn't even try not to open a executable file for reading. since doing this will not give error but you won't be able to read the file as it is a binary file.

it is god to always check whether the file was opened successfully or not after opening the file. If file was not opened successfully fopen will return NULL.

passwords = fopen(filePath, "r");

if(passwords == NULL)

{

printf(“\n Unable to open file”);

return -1;

}

3) execl(shellPath, "shell", NULL);

Before making a call to execl you should close the open file

close(passwords);

b)

1) char itemID[9];

After creating a char array one should always initialize the array as it may contain some garbage value.

char itemID[9] = “”;

2) scanf("%d", &unitsOrdered);

Since unitOrdered represents the quantity, it should always be non zero and non negative

c)

1) char fullName[MAX_LEN];

MAX_LEN should not be zero or negative as it used to define the size.

If ( MAX_LEN <=0 )

{

return error;

}

else

{

char fullName[MAX_LEN]

}

2) strcpy(fullName, firstName);

Before using the string functions you're expected to always make sure that the pointer that you are passing to the functions should not be NULL i.e. the pointers should always pass to certain memory location.

if (firstName && lastName)

{

strcpy(fullName, firstName);

strcat(fullName, " ");

strcat(fullName, lastName);

return fullName;

}

else

{

return error;

}
