GO by DEFINITION :

ABSOLUTE Refractive INDEX = speed in VACUUM / speed in medium

Since , Speed in medium ≤ Speed in vacuum ,

Absolute Refractive Index ≥1

Let the horizontal COMPONENT of both the velocities at POINT making an angle a (VELOCITY u) and at point making an angle b (say velocity v) is given as,

ux=ucosavx=vcosb
In a projectile motion, the horizontal component is ALWAYS same at every point. Thus we GET,
ucosa=vcosbv=ucosacosb

The CURRENT may be passed in a CONDUCTOR if the electricity can PASS through.

Heya mate here is your answer ⬇️⬇️⬇️
The cantilever TRUSS shown in Fig. P-250 carries a vertical load of 10.8 kN. The truss is supported by BEARING at A and B which exert the forces A , A , and B . The four forces shown CONSTITUTE two couples which must have opposite moment effects to prevent MOVEMENT of the truss. Determine the magnitude of the supporting forces.

Carry over factor : As name suggest it is something which is being carried from one end to other end by the MEMBER. as shown in the figure if MOMENT M applied at the end B in anti CLOCKWISE DIRECTION the moment felt by the end A is SUPPOSE Mab . Then in carry over will be defined as Mab/M, which is in this case 1/2.

The ANSWER is -: C. MAGNITUDE of CURRENT  

Hiiii


Tanya here to HELP you out....

so, your answer is "coefficient of static friction"


wanna know about how❓❓❓

let's check it

we know

f (LIM) = u(s) × N
=> u(s) = f (lim)/N

WHERE u(s) is coefficient of static friction...

so we GOT the ratio...

hope you got that... ☺☺

⭐Since we know that. ..

⭐Pressure = FORCE / Area ..

⭐thus it's SI UNIT IS N/m^2 or it is CALLED as Pascals ...

⭐The Dimensional FORMULA of the Pressure is given above

The moment of inertia of an object is a numerical value that can be calculated for any rigid body that is UNDERGOING a physical rotation around a fixed axis. It is based not only on the physical shape of the object and its DISTRIBUTION of mass but ALSO the specific configuration of how the object is rotating. So the same object rotating in different ways WOULD have a different moment of inertia in each SITUATION.

A SHEAR test is a field test used by geotechnical ENGINEERS to measure the STRENGTH of soil

Here, given
distance, d = 45 km = 45000m
and,speed of signal WAVE, V = 3 X 10^8
now, total distance covered by signal = 2d
(: - the signal reaches plane and returns)
now, we KNOW
v = d/ t
t = d/ v
t = 2 x45000/3 x10^8 = 3 x 10^-4

The plasticity index (PI) is a measure of the plasticity of a soil. The plasticity index is the size of the range of water contents where the soil exhibits plastic properties. The PI is the difference between the liquid limit and the plastic limit (PI = LL-PL). SOILS with a high PI tend to be clay, those with a lower PI tend to be silt, and those with a PI of 0 tend to have little or no silt or clay.

PI is used to relate to that how expansive the clays were. A PI lower than 20 to 24 was GENERALLY a safe area...but higher than that and we would then have to respond to swelling clay conditions.

It is a measure of the cohesive qualities of the BINDER resulting from the clay content. Also, it givessome indication of the amount of swelling and shrinkage that will result in the wetting and drying of that fraction tested. If some soils do not have SUFFICIENT mechanical interlock they require AMOUNTS of cohesive materials to give a satisfactory performance. A deficiency of clay binder may cause raveling of gravel wearing courses during dry weather and excessive permeability

Heya mate here is your answer.
Soil COMPACTION occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large PORES, less total pore volume and, consequently, a greater density. A compacted soil has a reduced RATE of both water infiltration and drainage.

We can wasly solve it by USING formula
SPEED = distance / time

The speed of car is 60 km per hour and it takes 3 hour to reach its DESTINATION SO
s = d / t
60 = x / 3
x = 60 ×3
x = 180 km /HR

the speed of car increased to 90 km /hr so
S = d/t
90 = 180 / t
90t = 180
t = 180 /90
t = 2hour
