ects experience a force of buoyancy when they are immersed in a FLUID. OBJECTS having density LESS than that of the liquid in which they are immersed, FLOAT on the surface of the liquid. If the density of the OBJECT is more than the density of the liquid in which it is immersed then it sinks in the liquid

tion:We know that CURRENT flows from negative potential to positive potential.In this case current will flow from -1000 V TOWARDS +3000 VOLTS .as ELECTRONS moves from negative to positive potential.and current will continue to flow until both batteries on are same potentials.then current flow will automatically stop.Explanation:Mark me as brainlist if you get this

the AVERAGE SPEED of the CAR is 1.5

I didn't quite get the question but if it is about evaporation, here you go.Explanation: Evaporation is a surface phenomenon. Water basically changes state from top LAYER in contrast with boiling where the bulk of water is boiled.If the temperature is HIGH and so is the area of the body, water will get EVAPORATED FASTER. Other factors are humidity and wind speeds which reduce rate of evaporation as they higher.Sorry if I did'nt quite get the question

As distance is the TOTAL path covered so 60+80 =140 mDisplacement is the shortest possible distance so if you will draw a VECTOR DIAGRAM for it you can easily FIND it asDisp. = √(60)^2 + (80)^2 = 100 m

When a NET zero external unbalanced force is applied on the body, it is possible for the object to be travelling with a non-zero VELOCITY. In FACT, once an object comes into MOTION and there is a condition in which its motion is unopposed by any external force; the object will continue to remain in motion.Explanation: plz mark me as brainliest and follow me

Answer: At the center of a current CARRYING coil, the magnetic field intensity is directly proportional to the current and INVERSELY proportional to the radius of the coil. So, if the current is DOUBLED and radius is halved, then the value of B increases by 4 times the INITIAL value.

The VOLTAGE of this CURRENT is 60 VOLTS. EXPLANATION:

tion:Multiply this CURRENT with the SERIES RESISTANCES to find the potential difference between then. Next to calculate the potential difference in each of the parallel resistances, USE current division formula. Now multiply respective current with the resistances. Voltage B/w A and B = Voltage b/w AC - ( Voltage b/w AB).

The wave EQUATION is an important second-order LINEAR partial differential equation for the description of waves—as they occur in CLASSICAL physics—such as mechanical waves (e.g. water waves, sound waves and seismic waves) or LIGHT waves. It arises in fields like ACOUSTICS, electromagnetics, and fluid dynamics.Explanation:plzzzzz mark me brainliest and like

Actually, may I tell you all a news that would be very interesting and HELPFUL, we have got medicine from herbal companies . I SWEAR it came in news, they being tried and they are working on PEOPLE with CORONA virus, but they can only cure small amount of infection. So, OBVIOUSLY since it's not curing properly and clearly they are not been refered as the medicine to Covid-19, but they are working less both scientist and herbal companies are searching about it.It's the truth and if you find it helpful pls follow and pls mark my answer as brainliest........Thank you

4√2 : 1.Explanation:SEE the ATTACHMENT MARK me as BRAINLIST if you GET this......

n is the force that opposes motion between any surfaces that are in contact. There are four TYPES of friction: static, SLIDING, rolling, and FLUID friction. Static, sliding, and rolling friction occur between solid surfaces.....❤️❤️

▪ Mass of block = 10kg▪ Angle of inclination = 30°▪ Distance covered by block = 5mTo FIND :▪ Work done to raise block from BOTTOM to the top.Concept :✏ This question is completely based on the concept of work-energy theorem.✏ As per WET, ☢ Work done = Change in energyCalculation :☞ If a body of mass m is RAISED through height h, then→ W = mgh→ W = mg(s × sinΦ)→ W = 10×10×5×sin30°→ W = 500/2→ W = 250J (Option-2)

tion:HOPE it will help you.make it Brainlist ANSWER. FOLLOW me.

Only METAL COIL WORKS for EDDYCURRENTS

it is difficult because when we walk on sand your FEET MOVES inside the sand bc our FEETS our BROAD

given: distance=  120 kmtime= 2 hoursfirst convert km to m.1km = 1000m120km = 1000 x 120            = 1,20,000now convert HOURS to seconds.1 hr = 60 min1min = 60 SEC∴ 1hr = 60 x 60 sec.                       = 3600 sec2 hr = 3600 x 2        = 7200 secnow, to find speed:formula: speed = distance ÷ time.∴ speed = 1,20,000 ÷ 7200                             =  16.6666666667 m/secExplanation: pls mark BRAINLIEST.

tion:When air is SUCKED out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the LIQUID to go inside the straw. SKIS have a large area to REDUCE the pressure on the snow. Hope it helpsplzzz mark as BRAINLIEST ✌️ ✌️✌️✌️✌️

the current it is same in series connection because the register which is connected is ALSO in series and in same line that is why when the current is allowed to move the current will be same at every register so at the END of the RESISTOR the TOTAL current is same

The charged CAPACITOR has a charge of 500mC. A charge X mC COMES to new capacitor.Then U1 = STORED ENERGY in 5mF before the connectionU2 = stored energy in 5mF after the connectionNow Loss energy = U1 - U2

tion:on the surface of the MOON accerleration due to GRAVITY is g/6 the TIME period of SECOND pendulum on earth is 2sec on earth, 2 =2π on moon, T= 2π 6gl dividing the above two equation, we get, T moon = 2 6s

→ Lateral magnification = -3→ Distance of object = -10cm→ Type of mirror : concaveTo FIND :→ Radius of CURVATURE of mirror.Formula :↗ Mirror formula :☢ 1/u + 1/v = 1/f = 2/R↗ Lateral magnification :☢ m = - v / UV denotes distance of imageu denotes distance of objectf denotes FOCAL lengthR denotes radius of curvaturem denotes magnificationCalculation :☞ m = - v / u☞ (-3) = - v / (-10)☞ v = -30cm→ 1/u + 1/v = 2/R→ 1/(-10) + 1/(-30) = 2/R→ (-3 - 1)/30 = 2/R→ -4/30 = 2/R→ -2/30 = 1/R→ R = -15cm

A BALL of mass m MOVING with velocity V, MAKES a head on elastic collision with a ball of the same mass moving with velocity 2V towards it. Taking direction of V as positive velocitie

Pressure is defined as the PHYSICAL force exerted on an OBJECT. The force APPLIED is perpendicular to the surface of OBJECTS per unit area. The BASIC formula for pressure is F/A (Force per unit area

tion:Magnitude of displacement is the difference between the starting and ENDING positions. For a curved path, it is equal to the chord length.Distance covered is the SUM of all the incremental displacements along the path. It is equal to the circumference of the path segment.The desired ratio…(magnitude of displacement / distance covered)can not be determined by acceleration. It REQUIRES a RADIUS of ROTATION to determine the curvature.

trueExplanation:By OHM's Law, the current FLOWING in a WIRE is INVERSELY proportional to the resistance of the wire. hope it will HELP you

d) same at all point in the motionExplanation:since the BODY is in the free fall the only acceleration action on it is acceleration due to GRAVITY (G) which is constant.and has a VALUE g = 9.8 m/s^2

No EXPLANATION:there is so much DIFFERENCE plz PLZZZ GIVE me brilliantist my FRIENDD

The ANSWER is h/t....MARK me as a BRAINLIEST..

Explanation:Basically, can't be integrated, if you don't tell that we're INTEGRATING it with what RESPECT.Anyway, LET that I'm integrating it with respect to Then,

...I don't KNOW the ANSWER........

i will SOLVE ........

the major difference between the resistance and the resistivity of the MATERIAL is that the resistance OPPOSES the FLOW of free electrons whereas the resistivity is the property of the material which DEFINES the resistance of the material having SPECIFIC dimension.
