ANSWER:

I don't KNOW SORRY

Newton's LAWS of motion RELATE an object's motion to the FORCES acting on it. In the first law, an object will not change its motion UNLESS a force acts on it. In the second law, the force on an object is equal to its mass times its ACCELERATION.

Answer:

HERE IS YOUR ANSWER..

Explanation:

ACCELERATION is the rate of change of the velocity of an object with respect to TIME. Accelerations are vector quantities. The ORIENTATION of an object's acceleration is given by the orientation of the net force acting on that object.

SI unit: m/s2

Here, BETA = Angle subtended by eyepiece

Alpha = Angle subtended by OBJECTIVE

m = ANGULAR magnification.

Answer:

Gravitational mass is MEASURED by comparing the FORCE of gravity of an unknown mass to the force of gravity of a known mass. ... INERTIAL mass is found by applying a known force to an unknown mass, measuring the acceleration, and applying NEWTON's Second Law, m = F/a..

Answer

Electric lines of force can be DEFINED as a way or path, it may be straight or CURVED, so that the tangent at any point to it gives the direction of the electric field intensity at that point.

Properties of lines of force :-

1-Lines of force originate from a positive charge and terminate to a negative charge.

2-The tangent to THELINE of force indicates the direction of the electricfield and electric force.

3-Electric lines of force are always normal to the SURFACE of charged body.

4-Two electric lines of force cannot intersect each other.

5-There are no lines of force inside the conductor

ANSWER:

The BULK modulus of a substance is a MEASURE of how resistant to COMPRESSION that substance is.

Answer:

If the DISPLACEMENT is 0, it doesn't necessarily mean that the BODY hasn't MOVED. For example, and OBJECT may have moved from point A to B and then back to A. In this case, there is distance, but displacement is 0

ANSWER:

I can't UNDERSTAND this QUESTION

what does it MEAN

Let us take:

Charge or VOLTAGE = V

Current = I  (amp)

Given that:

V = 250 V

I = 0.8 A

Average running time is 8 hours a day

Let's calculate the power from the formula....

= 250 × 0.8 = 200 W = 200 / 1000  kw

= 200/1000 × (8 × 60)

= 0.2 × 480 = 96 kwh

Also given that.

∵ costs is ₹5 for 6kwh

Which can be expressed as..

Therefore,

⇒ x = 96 x 5 / 6

x = 480 / 6

x = 80

So the monthly bill for 60 days will be ₹80

EXPLANATION:

Because, PERMITTIVITY means that:- the ability of a medium to hold the potential energy of a charge by means of electric field,

OR,

the resistance produced by a medium to disrupt the FLOW of charges and the interaction of Electric field.

suppose:- there are two charges (+q1) and (+Q2) and they are placed in free space so, the force acting between them is:- F=(1/4πE)*{(q1*q2)/r²} ,but when they placed in a medium for example a tank full of Hydrogen gas then (as we know every atom is a dipole) the flow of charges and the interaction of electric field gets disrupted by the positive and negative charges present in an atom. Due to this the force experienced by the charges also reduced.

[ THEREFORE THE FORCE IS INVERSELY PROPORTIONAL to the PERMITTIVITY of the membrane. ]

Hey dude here is your answer_____

=>Compared to the liquid phase, all MATERIALS in the SOLID phase have particle with more AVERAGE kinetic energy.... and a higher density....

The vapor pressure of the solution will be 17.45 mm of Hg

Explanation :

Given,

weight of water = 162 g

=> NUMBER of moles of water, n₁ = 162/18 = 19

weight of glucose = 9 GM

=> number of moles of glucose, n₂ = 9/180 = 1/20

we know that vapor pressure of pure water at 293 k, P⁰ = 17.5 mm of Hg

From RAOULT's law,

(P⁰-P)/P⁰ = n₂/n₁

=> 1 - P/P⁰ = 1/(20x19)

=> P/P⁰ = 379/380 = 0.99

=> P = 17.5 x 0.99 = 17.45 mm of Hg

Hence the vapor pressure of the solution will be 17.45 mm of Hg

Answer:

We will divide the Projectile MOTION into 2 simultaneously occuring 1D motions.

Along X axis :

\SF{ \therefore \: x = u \cos( \theta) \times t}∴x=ucos(θ)×t

\sf{ \implies \: x = 20 \cos( 60 \DEGREE) \times 1}⟹x=20cos(60°)×1

\sf{ \implies \: x = 20 \times \dfrac{1}{2} \times 1}⟹x=20×

So , COORDINATE will be :

\boxed{ \red{ \BOLD{ \sf{ \huge{(x,y) = (10,12.32)}}}}}

(x,y)=(10,12.32)

An isothermal process is a change of a SYSTEM, in which the temperature remains constant: ΔT =0. ... In other words, in an isothermal process, the value ΔT = 0 and THEREFORE the change in internal energy ΔU = 0 (only for an IDEAL gas) but Q ≠ 0, while in an adiabatic process, ΔT ≠ 0 but Q = 0.

Answer:

L = I x W. An OBJECT has a constant angular momentum when it is NEITHER speeding up nor slowing down. As the moment of INERTIA DECREASES, the angular rotation has to increase to keep the same angular momentum. Angular Momentum = The product of the body's moment of inertia and its angular velocity.
