Null type instruments require a null balance point to be achieved for accurate measurement, while deflection type instruments measure the quantity directly as a deflection on a scale. Null type instruments are more accurate but require more intricate adjustments, while deflection type instruments are simpler to use but may have lower accuracy.

What Difference between null type and deflection type instrument?
Null type instruments require balancing the unknown quantity with a known quantity to obtain a measurement, while deflection type instruments measure the unknown quantity based on the amount of deflection of a pointer or needle. Null type instruments are more accurate but require more setup, while deflection type instruments are simpler to use but may have less precision.
Which hypothesis states that no difference exists due to the variable under investigation?
The null hypothesis states that there is no significant difference or effect due to the variable under investigation. Researchers aim to reject the null hypothesis in favor of an alternative hypothesis that suggests a difference or effect exists.
What is null point?
A pointer variable which is declared but not initialized is called a NULL POINTER.ex: int *p;Please don't use the above. A NULL pointer is a specific value assigned to a pointer, just like any other value. NULL is a language-specific designation, and is guaranteed to be comparable to, unlike uninitialized variables, which can have any value.That is:int *a;int *b = NULL;int *c = (int *) malloc(sizeof(char));( a c) is NEVER true.NULL is a reserved word in most high-level languages, and indicates a specific value for assignment. It is commonly used to indicate that something has not yet been assigned a "real" value, or has had its contents deleted. It is an EXPLICIT value, and not just "undefined".In the context of pointers (which, remember, are really memory location addresses), a NULL pointer is one which has NO value, and thus does NOT point to any memory location. The difference between an uninitialized pointer and a NULL pointer is that most common languages do not specify what value an uninitialized pointer has upon creation (many, such as C, are assigned a random value), while a NULL pointer explicitly has NO value (which is the meaning of NULL).Many modern languages and compilers will assign NULL to a pointer upon initialization, but don't count on it. It is sloppy programming to do so, and can lead to many hard-to-find errors.
What's The difference between VOID and void?
In programming, "void" is a keyword used to indicate that a function does not return any value. "VOID" is a term generally used to describe something empty, null, or without substance.
Why null vector has a direction as it has magnitude 0?
The null vector is a special case where both magnitude and direction are undefined. This vector represents a point in space, rather than a physical quantity with magnitude and direction.
What Difference between null type and deflection type instrument?
Null type instruments require balancing the unknown quantity with a known quantity to obtain a measurement, while deflection type instruments measure the unknown quantity based on the amount of deflection of a pointer or needle. Null type instruments are more accurate but require more setup, while deflection type instruments are simpler to use but may have less precision.
What is the difference between equals 0 and equals NULL?
NULL is for pointers, 0, for numbers
What is the difference between 0 and null?
Nothing - 0, Zero and null are the same things
What is the difference between zero vector and null vector?
They are the same.
What is the difference between a null hypothesis and a research hypothesis?
The null hypothesis is the default hypothesis. It is the hypothesis that there is no difference between the control group and the treatment group. The research hypothesis proposes that there is a significant difference between the control group and the treatment group.
What is a NULL Point of a galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
What is the difference between array and string of array?
When we declare an array of characters it has to be terminated by the NULL , but termination by NULL in case of string is automatic.
What is the difference between two source hypothesis and two gospel hypothesis?
null
What is the major difference between the null and alternative hypothesis?
In research, a null hypothesis means that no results will be found. An alternative hypothesis means that results will be found.
What is the difference between alternative hypothesis and null hypothesis?
In research, a null hypothesis means that no results will be found. An alternative hypothesis means that results will be found.
In testing for differences between the means of two related populations the null hypothesis is?
That there is no difference between the means for the two populations.
What hypothesis states that there is no change no difference or no new finding?
null
