Given :

Length of the spring when it is KEPT in vertical position = 30 cm

Undeformed or natural  length of this spring = 40 cm

Stiffness or K of the spring = 10 N/cm

To Find :

What is the value of FORCE in the spring ?

SOLUTION :

We Know that in case of springs according to Hook's Law :

F = KΔx

Here , F is the force acting on the spring CAUSE a deformation of Δx in the length of the spring .

So in this case since the natural length is 40 cm and length after deformation is 30 cm , so thee is compression in the spring .

So ,  Δx = 40 - 30

             = 10 cm

So , the force acting on this spring will be :

N

   = N

   =100 N

Hence , 100 N force is acting on the spring .

Answer:

let the father's age be = x

the sons age be = y

sum of their ages = 55

x + y = 55 -------------1

twice of the age of the SON = 2y

sum of the age of the father and the twice of the age of the son = 70

x + 2y = 70-----------2

sub eq 1 and 2

x + y = 55

x + 2y = 70

symbol CHANGE then x and -x will be cancelled

then

-y = -15

y = 15

age of father = x = 55 - y = 55 - 15 = 40

therefore age of father = 40

age of son = 15

ANSWER: 3/5

Step-by-step EXPLANATION:

Answer:

15 / 4

Step-by-step EXPLANATION:

Polynomials WRITTEN in the form of x^2 - Sx + P REPRESENT S as sum of their roots and P as product of their roots.

 Here, POLYNOMIAL is x^2 - x - 4

So S = 1 and P = - 4

  P = αβ = - 4

S = sum of roots = 1

  ⇒ α + β = 1

 In QUESTION :

⇒ 1 / α + 1 / β - αβ

⇒ ( β + α ) / αβ  -  αβ

⇒ ( sum of roots / product of roots ) - product of roots

⇒ ( 1 / - 4 ) - ( - 4 )

⇒- 1 / 4 + 4

⇒ ( - 1 + 16 ) / 4

⇒ 15 / 4

Given :  a survey was conducted in a group of 100 students of a school. the RATIO of students who like mathematics and computer is 3:5. if 30 of them like both subjects and 10 of them like none of them,

To Find : number of students who like:  at most ONE subject.

Solution:

Mathematics = 3k

Computer = 5k

30 of them like both subjects

10 of them like none of them

Total = Math + Computer - Both  + None

100 = 3k  + 5k   - 30  + 10

=> 120 = 8k

=> k = 15

Mathematics = 45

Computer =  75

Mathematics only   = Mathematics - Both = 45 - 30 = 15

Computer only  = Computer - Both =75 - 30  = 45

at most one subject  = 100 - Both subjects 100 - 30  =  70

or none + computer only + Mathematics only = 10 + 45 + 15 = 70

70 Students like atmost one subject

Step-by-step explanation:

In mathematics, the degree of a polynomial is the HIGHEST of the degrees of the polynomial's MONOMIALS (INDIVIDUAL terms) with non-zero coefficients. The degree of a term is the sum of the EXPONENTS of the VARIABLES that appear in it, and thus is a non-negative integer.

Step-by-step explanation:

In mathematics, a linear EQUATION is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary EXPRESSIONS, provided they do not contain any of the variables. Wikipedia

Example: y = 2x + 1 is a linear equation:

When x increases, y increases twice as FAST, so we need 2x.

When x is 0, y is ALREADY 1. So +1 is also needed.

And so: y = 2x + 1.
