ANSWER:

How hot does the tire get? Typical TIRES EXPERIENCE a TEMPERATURE increase of roughly 50 degrees after RUNNING on the highway for a half-hour. If it's a 70-degree day, this suggests a tire temperature of about 120 degrees.

Answer:

Liquid is one of the three phases or state of matter. Fluids flow and has some VISCOSITY (thickness). Liquids also flows and it has volume, but no definite shape. A FLUID is a substance that lacks rigidity it cannot RESIST force when it is APPLIED to it.

Answer:

In PHYSICS, a force is any interaction that, when unopposed, will CHANGE the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a VECTOR quantity.

Volumetric analysis, any method of quantitative chemical analysis in which the amount of a substance is determined by measuring the volume that it OCCUPIES or, in broader usage, the volume of a SECOND substance that combines with the FIRST in known PROPORTIONS, more correctly called titrimetric analysis (SEE titration)

Answer:

log 2000/2

=log 1000

=log 10^3

=3 log 10

= 3 ×1

=3

Explanation:

log a - log b = log a/b

so log 2000- log 2 = log 2000/2 = log 1000

we can WRITE it as log 10^3

log a^b= b log a ( its an identity)

so we get = 3log 10

here BASE and no both are same i.e.10 so it becomes 1 and here we get 3×1 = 3

Explanation:

A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through GROUND- and atmosphere-transmitted MECHANICAL STRESS, the IMPACT and penetration of pressure-driven PROJECTILES, pressure damage, and explosion-generated effects.Bombs have been utilized since the 11th century starting in East Asia.

Centre of mass is the POINT at which the distribution of mass is EQUAL in all directions, and does not depend on gravitational field. Centre of GRAVITY is the point at which the distribution of weight is equal in all directions, and does depend on gravitational field.

Explanation:

The phase difference REPRESENTED by the Greek letter Phi (Φ). The complete phase of a waveform can be defined as 2π RADIANS or 360 degrees. Leading phase means, a waveform is AHEAD of another wave with the same FREQUENCY and Lagging phase means, a waveform is behind another wave with the same frequency.

The PRINCIPLE of superposition states that every CHARGE in space creates an electric field at point independent of the PRESENCE of other charges in that MEDIUM. The resultant electric field is a vector SUM of the electric field due to individual charges

Given INFO : The LENGTH of an edge of a cube increases by 2% when it is heated by 50°C.

To find : The percentage increase in volume will be...

solution : first find coefficient of linear expansion.

let edge length of a cube is a.

using formula, ∆l = l₀α∆T

if it is heated by 50°C , edge length increases by 2%.

so, 2% of a = a × α × 50

⇒α = 2/(100 × 50) = 4 × 10¯⁴/°C

so coefficient of volume expansion, γ = 3α = 4 × 10¯⁴/°C = 1.2 × 10¯³/°C

now ∆V = V₀ × γ × ∆T

⇒∆V/V₀ = 1.2 × 10¯³/°C × 50°C

⇒∆V/V₀ × 100 = percentage CHANGE in volume = 60 × 10¯³ × 100 = 6 %

Therefore percentage change in volume is 6 %

Shortcut :

percentage change in volume = 3 × percentage change in edge length, if percentage change in edge length is less than 10% .

Stokes LAW

A CREAMED emulsion increases the likelihood of coalescence due to the CLOSE proximity of the globules in the cream. Factors that influence the RATE of creaming are similar to those involved in the sedimentation rate of suspension particles, and are indicated by Stokes Law

Answer:

x’ = -x, where x is POSITION of observer and x’ is position of the image.

With mirror at 0.

So, if dx/DT = 2 m/s, dx’/dt = -dx/dt = - 30m/s.

using the classical formula for relative speed,

VREL = dx’/dt - dx/dt = -2dx/dt = -60m/s.

So, the image is approaching the observer at 60 m/s.

Hence option B is the right answer

Explanation:

answer is 60 m/ s

Explanation:

Resonance occurs in a series circuit when the supply frequency causes the VOLTAGES across L and C to be equal and opposite in phase

Thus far we have analysed the behaviour of a series RLC circuit WHOSE source voltage is a fixed frequency steady state SINUSOIDAL supply. We have also SEEN in our tutorial about series RLC circuits that two or more sinusoidal signals can be combined USING phasors providing that they have the same frequency supply.

SINCE it is FLOWING in parallel combination then it's sum will be
