Q19. If one angle in a parallelogram is a right angle, how can we say that all the other angles areright angles? Draw and label a parallelogram and explain it giving appropriate reasons.​

Answer»

Answer:

Given - In a parallelogram ABCD, angle ADC = 90 degree

To prove - other ANGLES of parallelogram is 90 degree

construction- draw DIAGONAL AC and BD

proof - In triangle ACD AND BCD

AD= BC

AO=OC

DO=BO

therefore , triangle ACD congruent to triangle BCD

therefore , angle ADC = angle BCD ( BY CPCT )

but angle ADC + angle BCD = 180 degree

90 degree + angle BCD = 180 degree

angle BCD = 180 - 90

angt BCD = 90

similarly , angle CBA = 90

angle BAD = 90

proved

A man travels 400 km partly by train and partly by car. If he covers 240 km by train and rest by car, it takes 6 hours. But if he travels 180 km by train and rest by car, he takes 15 minutes lesser. Find the speed of the train and that of the car.

Answer»

Answer:

Train = 60 km/hr

Car = 80 km/hr

Step-by-step explanation:

Given that,

A man travels 400 km.

He travels the distance by train and car.

To find the speed.

Let the speed of train be x km/hr and that of car is y km/hr.

We know that,

Speed = Distance/Time

=> Time = Distance/Speed

Now, in FIRST case, we have,

Distance by train = 240 km

Distance by car = (400-240) = 160 km

Time taken = 6 hr

Therefore, we have,

=> 240/x + 160/y = 6 ......(1)

Now, in SECOND case, we have,

Distance by train = 180 km

Distance by car = (400-180) = 220 km

Time taken = 6 - 15/60 = 6-¼ = 23/4 hr

Therefore, we will get,

=> 180/x + 220/y = 23/4 ......(2)

Multiplying eqn (1) with 3 and eqn (2) with 4 and subtracting, we get,

=> 480/y - 880/y = 18 - 23

=> (880-480)/y = 23 - 18

=> 400/y = 5

=> y = 400/5

=> y = 80

SUBSTITUTING this value in eqn (1), we get,

=> 240/x + 160/80 = 6

=> 240/x = 6 - 2

=> x = 240/4

=> x = 60

Hence, the speed of the train and that of the car is 60 km/hr and 80 km/hr respectively.

Answer:

In an isosceles triangle 2 SIDES are EQUAL so

Side 1 = 4 \frac{3}{4}

Side 2 = 4 \frac{3}{4}

Side 3 must be =  PERIMETER - (Side 1 + Side 2)

                         =  20 -  (4\frac{3}{4} + 4\frac{3}{4})

                         = 20 - 9.5

                         = 10.5

Hence Side 3 = 10.5 cm

The location of or 2.44 is between 2 and 3.

Given:

To FIND:Number line

Solution:

As we, all know that \SQRT{6}  is equal to 2.44

Therefore, to represent \sqrt{6}or number 2.44 on the number line down below is a graph to SHOW the point 2.44

First line up the x-axis after that plot the point 2.44 in between 2 and 3 we get the location of 2.44 on the positive x axis.

Number line is attached below.

Therefore, point 2.44 REPRESENTS the location of √6 or 2.44 is between 2 and 3.

Derivation of the equation of the motion​

Answer»

Derivation of Equation of Motion

There are mainly three equations of motion which describe the relationship between velocity, time, acceleration and displacement.

First, consider a body moving in a straight line with uniform acceleration. Then, let the initial velocity be u, acceleration be a, time period be t, velocity be v, and the distance travelled be S.

The equation of motions derivation can be DONE in three ways which are:

Derivation of equations of motion by Simple Algebraic Method

Derivation of Motion by Graphical Method

Derivation of Motion by Calculus Method

Below, the equations of motion are derived by all the three methods in a simple and easy to understand way.

Derivation of First Equation of Motion

The first equation of motion is:

v = u + at

Derivation of First Equation of Motion by Algebraic Method

It is known that the acceleration (a) of the body is defined as the RATE of change of velocity.

So, the acceleration can be written as:

a = v − ut

From this, rearranging the terms, the first equation of motion is obtained, which is:

v = u + at

Derivation of First Equation of Motion by Graphical Method

Consider the diagram of the velocity-time graph of a body below:

Derivation Of Equation Of Motion

In this, the body is moving with an initial velocity of u at point A. The velocity of the body then changes from A to B in time t at a uniform rate. In the above diagram, BC is the final velocity i.e. v after the body travels from A to B at a uniform acceleration of a. In the graph, OC is the time t. Then, a PERPENDICULAR is drawn from B to OC, a parallel line is drawn from A to D, and another perpendicular is drawn from B to OE (represented by dotted lines).

Following details are obtained from the graph above:

The initial velocity of the body, u = OA

The final velocity of the body, v = BC

From the graph,BC = BD + DC

So, v = BD + DC

v = BD + OA (since DC = OA)

Finally, v = BD + u (since OA = u) (Equation 1)

Now, since the slope of a velocity-time graph is equal to acceleration a,

So,

a = slope of line AB

a = BD/AD

Since AD = AC = t, the above equation becomes:

BD = at (Equation 2)

Now, combining Equation 1 & 2, the following is obtained:

v = at + u

Derivation of First Equation of Motion by Calculus Method

It is known that,

Derivation Of Equation Of Motion

So,

Derivation Of Equation Of Motion

Derivation of Second Equation of Motion

The second equation of motion is:

S = ut + ½ a2

Derivation of Second Equation of Motion by Algebraic Method

Consider the same notations for the derivation of the second equation of motion by simple algebraic method.

Derivation Of Second Equation Of Motion

Derivation of Second Equation of Motion by Graphical Method

Taking the same diagram used in first law derivation:

Derivation Of Equation Of Motion

In this diagram, the distance travelled (S) = Area of figure OABC = Area of rectangle OADC + Area of triangle ABD.

Now, the area of the rectangle OADC = OA × OC = ut

And, Area of triangle ABD = (1/2) × Area of rectangle AEBD = (1/2) at2 (Since, AD = t and BD = at)

THUS, the total distance covered will be:

S = ut + (1/2) at2

Derivation of Second Equation of Motion by Calculus Method

Velocity is the rate of change of displacement.

Mathematically, this is expressed as

v=dsdt

Rearranging the equation, we get

ds=vdt

Substituting the first equation of motion in the above equation, we get

ds=(u+at)dt =(udt+atdt) ∫s0ds=∫t0udt+∫t0atdt s=ut+12at2

Derivation of Third Equation of Motion

The third equation of motion is:

v2 = u2 + 2aS

Derivation of Third Equation of Motion by Algebraic Method

Derivation Of Third Equation Of Motion

Derivation of Third Equation of Motion by Graphical Method

Derivation Of Equation Of Motion

The total distance travelled, S = Area of trapezium OABC.

So, S= 1/2(SumofParallelSides)×Height

S=(OA+CB)×OC

Since, OA = u, CB = v, and OC = t

The above equation becomes

S= 1/2(u+v)×t

Now, since t = (v – u)/ a

The above equation can be written as:

S= 1/2(u+v)×(v-u)/a

Rearranging the equation, we get

S= 1/2(v+u)×(v-u)/a

S = (v2-u2)/2a

Third equation of motion is obtained by solving the above equation:

v2 = u2+2aS

Derivation of Third Equation of Motion by Calculus Method

It is known that,

Derivation Of Equation Of Motion

These were the detailed derivations for equations of motion in the graphical method, algebraic method and calculus method.

Equations of Motion Formula

Equations of motion Formula

First equation of motion v=u+at

Second equation of motion s=ut+12at2

N

Third equation of motion v2 = u2+2as
