It is LIQUID I THINK........

No. In Oscillatory motion the object MOVES as a single unit but in vibratory some PARTS show small MOVEMENTS. OSCILLATOR motion very FAST is called vibratory

Apply rho=r*a/L
where rho is resistivity
r is RESISTANCE
a is area

Phone volume means the mass and WEIGHT of Ur phone if u use Ur phone for 1 hour then it's mass increases as its battery got OVERHEATED so if we use MOBILE phone with rest of time then mass INCLUDES and Ur phone volume decreases

Electrical resistivity is a fundamental property that QUANTIFIES how strongly a GIVEN material opposes the flow of electric current. A LOW resistivity indicates a material that readily ALLOWS the flow of electric current.

The pressure exerted by atmosphere is CALLED atmospheric pressure.
it DEPENDS UPON two factors
altitude
temperature

It DEPENDS on
1)DEPTH of fluid.
2)DENSITY of fluid
3)ACCLERATION of gravity

If we FORCE to any BODY then it CHANGE postoin

Impulse applied to an object produces an equivalent vector CHANGE in its linear MOMENTUM, also in the same direction. The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unitof momentum is the KILOGRAM METER per second

A=v2-u2/t
a =f/m
hope you GOT it

This is the CONVEX mirror......plz EXPLAIN me what U WANT in this

Raman Effect is a CHANGE of WAVELENGTH exhibited by some of the radiation scattered in a MEDIUM. The effect is specific to the molecules which CAUSE it, and so can be used in spectroscopic analysis

I hope helps u

✨Force:-

It is the force enables us to do any work.

To do anything either we push or pull the object. Therefore, push or pull is called force.

• Example:- To open a door either we push or pull it.
• A drawer is pulled to open and pushed to close.

✨Effects of force:-

1.Force can stop a moving body:- Example:- by applying brakes a running cycle or running vehicle can be stop.

2.Force can change the direction of moving body:- example:- by applying force i.e by moving handle the direction of a running bicycle can be changed.

3.Force can change speed of moving body:- example:- by accelerating the speed of a running vehicle can be increased by applying brakes the speed of a running vehicle cam be decreased.

An electric potential (also CALLED the electric FIELD potential, potential drop or the electrostatic potential) is the amount of work needed to MOVE a unit positive charge from a REFERENCE point to a specific point inside the field without PRODUCING any acceleration.

The BUOYANT force of water on the object = weight of water displaced by it 


Weight of water displaced by the object = 10N

Buoyant force acting on the object = 10N

Weight of object in water = weight of object -buoyant force 

Weight of object in water = 50N -10N
Weight of object in water = 40N

The flow of charge in the CONDUCTOR perpendicular to the area of CROSS SECTION is CALLED electric current

Because HYDROGEN is lighetes has KNOWN and so it FLOATS in AIR

Primary cell cannot be recharged whereas a secondary cell can be recharged.In a primary cell chemical reaction is irreversible whereas in a secondary cell chemical reaction is reversible.The internal resistance is high for a primary cell whereas it is LOW for a secondary cell.In a primary cell, chemical ENERGY is converted into electrical energy when CURRENT is DRAWN from it whereas in a secondary cell electrical energy is converted into chemical energy when current is passed through it and chemical energy is converted into electrical energy when current is drawn from it. A primary cell is light and  less expensive whereas  a secondary cell is heavy and expensive.

Hey,

When the body changes it's position with ACCORDANCE to TIME in any RESPECTIVE DIMENSION , the body is said to be in motion.

Thanks

At t=0

v=30*(5/18)m/s

v=8.33 m/s

t=2

v1=33.6*(5/18) m/s

v1=9.33 m/s

t=4

v2=37.2*(5/18)

v2=10.33 m/s

Since the velocity is INCREASING 1m/s every 2 sec THEREFORE it is a uniform acceleration of 0.5 m/s^2

Answer:

There are OFTEN two types of motion acting on one body for example wheel of a scooter

Explanation:

• The wheel of a scooter turns in a rotational motion in its axis while also moving forward on the ROAD.
• There are certain other examples which include two KINDS of motion on one object at the same time.
• The other example can be a ROCK rolling down an inclined surface. Two motions acting are rolling motion and forward motion.

PLEASE FOLLOW me I will follow you BACK please please

Answer:

Volume = V

density= d

density of water =q = 1000 kg/m3

weight in AIR = w= Vgd

Buoyant force= (2V/3)qg

density of other liquid =p

volume of body inside water= V- 3V/4= V/4

buoyant force = (V/4)pg

as in both SITUATION the body will float so,

(2V/3)qg = (V/4)pg

p = 8q/ 3

p = 8 X 1000/3

p= 8 /3 x 10³

Heat can be TRANSFERRED from oneplace to another by THREE METHODS:conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass.

I DONT KNOW ..... SORRY

Becoz earthen POST has SMALL pores from which water evaporates continusely . the heat required for the PROCESS of evaporation is TAKEN from the earthen pot and from the water it in

Area of square Park = (100 ± 0.2) m²
we know, area of square , A = L² , Where L is SIDE length.
Given, A = 100
∴ L² = 100 = 10²
⇒ L = 10 m
For getting error , we have to apply formul,
∆A/A = 2∆L/L
Given, A = 100 , ∆A = 0.2 , L = 10
∆L = ?
∴ 0.2/100 = 2 × ∆L/10
⇒0.2/100 × 10 = 2 × ∆L
⇒ 0.02/2 = ∆L
⇒ ∆L = 0.01

Hence, side of park = (10 ± 0.01) m

Hippocampus is a paart of brain.

The hippocampus is a PART of the limbic SYSTEM. The limbic system is the area in the brain that is associated with memory, emotions, and motivation. The limbic system is located just above the brain stem and below the cortex. The hippocampus itself is HIGHLY INVOLVED with our MEMORIES.

Hola User__________________

Here is Your Answer..!!!
_________________________

⭐Actually welcome to the CONCEPT of the RAY OPTICS..

⭐Basically we know that ... Power of a lens is the reciprocal of the focal length in metres..

⭐So here , P = 1/f

⭐so the focal lenght of the lense will be f = 1/P

⭐we get the focal length as f = 1/2 ==》 f = + 0.5 m


⭐Now from here we can conclude that .. as the Focal length of the Given unknown lens is Positive 0.5 ...


⭐Then WE CAN CONCLUDE THAT THE GIVEN LENS IS A CONVEX LENS AS CONVEX LENS HAS ALWAYS A POSITIVE FOCAL LENGTH ..
