AnswerData: d 1 =10cm=0.1m,v 1 =2m/s,v 2 =4m/sBy the equation of continuity, the RATIO of the SPEED isv 2 v 1 = A 1 A 2 =( d 1 d 2 ) 2 ∴ d 1 d 2 = v 2 v 1 = 42 = 2 1 =0.707∴d 2 =0.707d 1 =0.707(0.1m)=0.0707m

ACTIVITY: Rub a COMB through your dry hair(not oiled hair) for sometime. ... When the comb is rubbed in your dry hair, it acquires a property called electrostatic charge. Electrostatic charge can exert a force called electrostatic force. It is because of this force that the BITS of paper gets ATTRACTED to your comb.Explanation:hope it HELPS

Inverse Square LawCharge Interactions RevisitedCoulomb's LawInverse Square LawNewton's Laws and the ELECTRICAL ForceScience in general and Physics in particular are concerned with relationships. Cause and effect is the focus of science. Nature is probed in order to find relationships and mathematical patterns. SCIENTISTS modify a set of conditions to see if there is a pattern of BEHAVIOR in another set of MEASURABLE quantities. The goal is to answer the question of how does a change in a set of variables or conditions causally affect an observable outcome? In Physics, this search for cause and effect leads to questions like:How does a force

To cross the river in shortest time boat MUST be ROWED ALONG the width of river i.e., boat must be rowed perpendiculat to the BANK of 90∘ with the flow of water . because width of river is the shortest distance . so VELOCITY must be taken in that direction to obtain shortest time

it's TOTALLY because of FRICTIONAL FORCE

It should only be performed when a person shows no signs of life or when they are:unconscious.unresponsive.not breathing or not breathing normally (in cardiac ARREST, some PEOPLE will TAKE occasional gasping BREATHS – they still NEED CPR at this point. Don't wait until they are not breathing at all).

Show that the TORQUE on an ELECTRIC dipole PLACED in a UNIFORM electric field is. τ =P ×E.

While adding a SCALAR to a vector is impossible because of their different dimensions in space, it is POSSIBLE to MULTIPLY a vector by a scalar. A scalar, however, cannot be MULTIPLIED by a vector.

a).Zero EXPLANATION:As Everywhere in an equipotential surface,the POTENTIAL difference between any POINT is equal to zero.So is the work DONE equals zero

5 Situations where we USE diffusion in our day to day life​ are :-1. You can smell PERFUME because it diffuses into the AIR and makes its way into your nose.2. Cigarette smoke diffuses into the air.3. A few crystals of potassium permanganate in water will diffuse and turn the water purple.4. LEAVE a SODA bottle open and the carbon dioxide bubble will diffuse and leave it flat.5. A tea bag placed in a cup of hot water will diffuse into the water.PLZ MARK ME AS BRAINLIEST :)

In the game of CRICKET, the 'bails' FALL when the BALL strikes them. This is an example of A FORCE.

The factors that affect buoyancy are… the density of the fluid. the VOLUME of the fluid displaced. the local acceleration due to gravity.The BUOYANT force is not affected by… the MASS of the immersed OBJECT. the density of the immersed object.

(a) The resistivity of copper wire is very low. The connections are made of thick copper wires to minimize the resistance of connecting wires. Because the connection resistance have not been accounted in the formula, (v Resistance is inversely proportional to cross-sectional area, so thick wire has low resistance).(b) The BALANCE point is OBTAINED in the middle of the meter bridge wire so as to increase the sensitivity of the meter bridge and there by no deflection in the galvanometer.(c) ALLOYS, such as manganin or constantan are used for making meter bridge wire due to their low temperature coefficient of resistance and HIGH resistivity. Due to which the resistance of the wire does not change with increase in temperature of the wire due to flow of CURRENT.Given: A resistance ofRΩ draws current from a potentiometer. The potentiometer has a total resistance R 0 Ω. A voltage V is supplied to the potentiometer.To find an expression for the voltage across R when the sliding contact is in the middle of the potentiometer.Solution:Total resistance is given by,R tot = 2R 0 + 2R 0 +R2R 0 ×R = 2(R 0 +2R)R(R 0 +4R) Total current through the device is given by, I tot = R tot V = R(R 0 +4R)2V(R 0 +2R) Current through resistance R is given by,I 2 =I tot × 2R 0 +R2R 0 ⟹I 2 =I tot × R 0 +2RR 0 ⟹I 2 = R(R 0 +4R)2V(R 0 +2R) × R 0 +2RR 0 ⟹I 2 = R(R 0 +4R)2VR 0 Voltage across resistance is given byI 2 R= (R 0 +4R)2VR 0 is the required expression for the voltage when sliding contact is in the middle of the potentiometerhope it helps youMark me as brilliant

this property in our daily lives. Natural gas is compressed to liquid gas and stored in gas CYLINDERS and USED as fuel. By compression of air we can blow things like balloon and at the same TIME deflate them. By compression of gases we can pump air into the BICYCLE tire USING a pump.

e-time graphsIf an object moves along a straight line, the distance travelled can be represented by a distance-time GRAPH.In a distance-time graph, the gradient of the line is EQUAL to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is MOVING. Please mark me as brainliest

AnswerExplanation:For an OBJECT rotating about an AXIS, every POINT on the object has the same angular velocity. The TANGENTIAL velocity of any point is proportional to its DISTANCE from the axis of rotation. Angular velocity has the units rad/s.

As the natural gas DELIVERED to your HOME is 85 to 95 percent METHANE, natural gas leaks are predominantly methane. While methane poses the greatest threat to the climate because of its greenhouse gas potency, natural gas contains other hydrocarbons that can DEGRADE regional air quality and are bad for human healthmark as brainliest if it helps you!!!!

l quantities are classified into two types. ... These are LENGTH, mass, time, electric current, temperature, luminous intensity and AMOUNT of substance. Quantities that can be expressed in TERMS of fundamental quantities are CALLED derived quantities. For example, area, volume, velocity, acceleration, force.

tion:Uniform accleration when a BODY moves in a constant SPEED and constant time is KNOWN as uniform acclerationNon uniform accleration when a body moves in an UNEQUAL interval of time and speed is known as non uniform accleration

ixed conductor at a fixed temperature, which of the following ... E=Jp is not the statement for OHM's law. this law is one of the most basic laws and HELPS to CALCULATE many other quantities such as, power, efficiency, voltage, CURRENT and resistance. Therefore this statement is correct.

ভরবেগের মাত্রা MLT^-1Explanation:ভরবেগ, P = MV যেখানে, m = ভর ও V = বেগ।ভরবেগের একক kgm/s.তাহলে,ভরের মাত্রা = Mদূরত্বের মাত্রা = Lও সময়ের মাত্রা = Tতাহলে, ভরবেগের মাত্রা [P] = [ভর * দূরত্ব/সময়] = [ML/T]

Not clear that which can be!!EXPLANATION:A PUSH or pull which CHANGES or tends to change shape, size and direction of any object is called FORCE.
