Why 2's complement is better than sign magnitude?
Because sign magnitude has 2 representations for 0 100000000000000000000 ( = -0) and 000000000000000000000 ( = +0) Clearly, -0 = +0. However, because of these two representations, different machines process sign magnitude differently at 0. Two's complement avoids this problem and is therefore used much more commonly.
How can you represent a negative integer in a computer system?
There are many different ways this can be done using binary form:signed magnitude, one bit is the sign (i.e. 0=+, 1=-) and the other bits are the magnitude of the number (this is analogous to how we write negative integers on paper)ones complement, invert every bit of the magnitude of a number to get its negative formtwos complement, invert every bit of the magnitude of a number then add one to get its negative form (most computers now use this form as the arithmetic circuits to do calculations in this form are simpler and thus less expensive than for the other two.There are also corresponding ways this can be done using decimal forms (e.g. BCD, 2 of 5, excess-3)signed magnitude, one bit or digit is the sign (i.e. 0=+, 9=-) and the other digits are the magnitude of the number (this is analogous to how we write negative integers on paper)nines complement, subtract every digit of the magnitude of the number from 9 to get its negative formtens complement, subtract every digit of the magnitude of the number from 9 then add one to get its negative form

Explain the methods which are available to store negative numbers and how are they used. Which method is mainly used today and why?
signed magnitude, one bit indicates the sign of the number and the other bits indicate the positive magnitude of the number (this system has two representations for zero: +0 and -0)one's complement, positive numbers are represented as their positive magnitude and negative numbers are represented as the complement of their positive magnitude (this system has two representations for zero: +0 and -0)two's complement, positive numbers are represented as their positive magnitude and negative numbers are represented as the complement of their positive magnitude plus one (this system is asymmetric about zero, with one more negative value than positive)offset binary, numbers are represented as the positive sum of their actual value and an offset (this system is asymmetric about zero, typically with one more negative value than positive)Most modern systems use two's complement for fixed point numbers (because the arithmetic circuitry is simpler than the others) and a combination of signed magnitude and offset binary for floating point numbers (because this format allows the same instructions for comparing fixed point numbers to also be used to compare floating point numbers, reducing the number of different instructions and the circuitry to implement them),

How do you determine the magnitude of two equal forces?
To determine the magnitude of two equal forces, you can simply multiply the magnitude of one force by 2, as they are equal. This is because the total force is the sum of the individual forces acting in the same direction.

Determine the magnitude and direction of F so that the particle is in equilibrium?
To have equilibrium, the net force acting on the particle must be zero. The magnitude of force F must be equal in magnitude (but opposite in direction) to the resultant of all other forces acting on the particle. Therefore, to determine F, you need to calculate the vector sum of all other forces acting on the particle and then determine the magnitude and direction for F.
How can one determine the order of magnitude of a given quantity?
To determine the order of magnitude of a given quantity, you can look at the number of digits in the quantity and focus on the most significant digit. The order of magnitude is typically represented as a power of 10 that is closest to the value of the quantity. For example, if the quantity is 450, the order of magnitude would be 102 or 100.
What are the disadvantages of sign magnitude?
One disadvantage of sign-magnitude representation is that it has two representations for zero (positive zero and negative zero), which can lead to confusion in arithmetic operations. Additionally, sign-magnitude representation is not suitable for comparison operations, as it requires additional steps to check for equality because of the separate sign bit.
