HELLO mate ♥️♥️

IRC suggests the coefficient of LONGITUDINAL friction as 0.35-0.4 depending on the speed and coefficient of LATERAL friction as 0.15.

HOPE it helps

Answer:

Explanation:

distance between the stations = 300km

let the speed of the FIRST motorcyclist be (x)km/h

so according to the question the second motorcyclist speed will be (x + 7) km/h

after 2 hours the speed of the mortor cyclists are 1st biker = 2 x (x ) = 2xkm/h

2nd biker = 2 (x + 7) = (2x + 14) kmph

so according the question

2x + 2 (x + 7) + 34 = 300

2x + 2x + 14 + 34 = 300

4x + 48 = 300

4x = 300 - 48

x = 252/4

x = 63 kmph

x + 7 = 70 kmph

Answer:

100√2 is the ACCELERATION of a BODY when 5√2 FORCE ACTS on the body

Answer:

By differentiating →v with respect to time we obtain the acceleration →a=→α×→r+→ω×→v, where →α=d→ω/dt is the angular acceleration. The FIRST term, →α×→r, is PARALLEL to the velocity vector and is NORMALLY CALLED tangential acceleration. The second term, →ω×→v is radially inwards and is called centripetal acceleration.

Explanation:

In a triangle, if the square of one side is EQUAL to the sum of square of other two SIDES then prove that the triangle is right angled triangle.

________________________

GIVEN : AC² = AB² + BC²

To prove : ABC is a right angled triangle.

Construction : Draw a right angled triangle PQR such that, angle Q = 90°, AB = PQ, BC = QR.

Proof : In triangle PQR,

Angle Q = 90° ( by construction )

Also,

PR² = PQ² + QR² ( By using Pythagoras theorem )...(1)

But,

AC² = AB² + BC² ( Given )

Also, AB = PQ and BC = QR ( by construction )

Therefore,

AC² = PQ²+ QR²....(2)

From eq (1) and (2),

PR² = AC²

So, PR = AC

Now,

In ∆ABC and ∆PQR,

AB = PQ ( By construction )

BC = QR ( By construction )

AC = PR ( Proved above )

Hence,

∆ABC is CONGRUENT to ∆PQR by SSS criteria.

Therefore, Angle B = Angle Q ( By CPCT )

But,

Angle Q = 90° ( By construction )

Therefore,

Angle B = 90°

Thus, ABC is a right angled triangle with Angle B = 90°

PLZ MAKE DIAGRAM of this QUESTION

Answer:

Explanation:

RECALL E=hcλ

E=(6.626×10−34)(3.0×108)560×10−9

E=3.550×10−19J

Each PHOTON carries 3.550×10−19J of energy.

A 100W SOURCE MEANS that it outputs 100J of energy every second.

number of photons emitted = total energy output in one second / energy carried per photon

n=1003.550×10−19=2.8×1020 (2sf)

If n is the number of free electrons PER unit VOLUME of the conductor, then the total number of free electrons in the conductor=A/n. ... Hence the current flowing through a conductor is DIRECTLY proportional to the DRIFT velocity. Explanation and Example. In a conductor there are large number of free electrons.

Answer:

An ELASTIC COLLISION is one that conserves internal kinetic energy. CONSERVATION of kinetic energy and MOMENTUM together allow the final velocities to be calculated in terms of initial velocities and masses in one dimensional two-body COLLISIONS.

Answer:

Moment of force (or TORQUE) depends on two factors ,the magnitude of the force applied and the perpendicular distance of the line of action from the axis of rotation. HENCE, in ORDER to reduce this turning EFFECT (or moment of torque) ,one can either reduce the force applied or DECREASE the distance between the line of action and axis of rotation.

ans : 4

if two capacitors will be in SERIES and two capacitors will be in parallel as shown in figure then, EQUIVALENT CAPACITANCE will 5 microfarad.

Let see AB and BC capacitors are in series

so, equivalent capacitance {X} of it = 2microfarad/2 = 1 microfarad { in series 1/CEQ = 1/C1 + 1/C2}

DE and GF capacitors are in parallel ,

so, equivalent capacitance { Y} of it = 2 + 2 = 4 microfarad { in parallel, Ceq = C1 + C2 }

now, X and Y capacitors are in parallel then,

Ceq = 4 + 1 = 5 microfarad.

Conductivity is the measure of the ease at which an electric charge or heat can pass through a MATERIAL. A conductor is a material which gives very LITTLE resistance to the flow of an electric current or THERMAL energy.

N1 = 62

w1 = 5893

w2 = 4358

total EXTENT of fringes is constant for both wavelengths

i.e. n1w1D/d = n2w2D/d

N2 =62×5893/4358 = 84 (approx)
