mate ⭐⭐here is ur answer ➖➖➖➖➖➖➖⬇Given .. (1) time taken to take 10 shots=1 SEC ==> time taken to take one shot= 1/10 sec (2) Distance travelled by BALL while camera took 6 shots =15 METER We know , speed= distance/time Distance=15m Time= Not known... LETS find out the time to take six shots FIST shot was taken after = 0sec (as first short was taken at beginning) Second shot taken after = 1*(1/10) = 1/10 seconds Third short taken after = 2*(1/10) =2/10 seconds Similarly .. sixth shot taken after = 5*(1/10) =5/10 Now.. speed = distance/time = 15 / (5/10) = 30 m/second Hope, it helps.please mark as a brainliest ✌☺❤✍

t of energy is Joule (J).COMMERCIAL unit of energy is Kilowatt Hour (KwH)1 KwH = 3.6 x 10^6 J1 Kw H = 1000 w x 3600 s = 3.6 x 10^{6} w s = 3.6 x 10^{6} J

rough two pointsThe LINE through two distinct points (x1, y1) and (x2, y2) is given by(1) y = y1 + [(y2 - y1) / (x2 - x1)]·(x - x1),where x1 and x2 are assumed to be different. In case they are equal, the equation is simplified tox = x1and does not require a second point.Equation (1) can also be written asy - y1 = [(y2 - y1) / (x2 - x1)]·(x - x1),or even as(x2 - x1)·(y - y1) = (y2 - y1)·(x - x1),where one does not have to WORRY whether x1 = x2 or not. However, the SIMPLEST for me to remember is this(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)which is not as universal is the one before.General equationA straight line is defined by a linear equation whose general form isAx + By + C = 0,where A, B are not both 0.The coefficients A and B in the general equation are the components of vector n = (A, B) normal to the line. The pair r = (x, y) can be looked at in two ways: as a point or as a radius-vector joining the origin to that point. The latter interpretation shows that a straight line is the locus of points r with the propertyr·n = const.That is a straight line is a locus of points whose radius-vector has a fixed scalar PRODUCT with a given vector n, normal to the line. To see why the line is normal to n, take two distinct but otherwise arbitrary points r1 and r2 on the line, so thatr1·n = r2·n.But then we conclude that(r1 - r2)·n = 0.In other words the vector r1 - r2 that joins the two points and thus lies on the line is perpendicular to n

pull the north end away from the magnet the current FLOWS in the opposite direction so that the ASSOCIATED MAGNETIC field points with its south pole towards the magnet it does not MATTER of course whether you keep the coil stationary and move the magnet or keep the magnet stationary and move the coil

the RIGHT ANSWER ...

tem of THREE FORCES in equilibriummust be coplanar and either beconcurrent or be parallel. Proof: Assume that the two of the forces F1and F2 intersect at a point A. The resultant of these two forces is given by, The third force is EQUAL and opposite of this force.

ve mirror would be best suited for USE in a solar cooker because it REFLECT and focus the sunlight at a point. The temperature at that point INCREASES which heats and cooks the food PLACED at that point.

T IS MORE IMPORTANT TO PREPARE THE FOOD IN PLANT AND CO2 IS ALSO IMPORTANT FOR IT I THINK U BETTER UNDERSTAND BY SEEING THE VIDEO OF ASHISH CHANCHALANI

otassium (K)can LOOSE electrons more EASILY because it has a bigger shell than NA and down the group the effective nuclear charge experienced by the VALENCE electrons decreases due to addition of new shells.Hence, the valence electrons are farther from the nucleus and can be lost easily

re will be the FLOW of current because ,if I had ever seen thick wires on the big POLES flowing with currentthen I must be TRUE questionthank U if it helps u pls follow me [MR= BRAHMAN ]~...

sec, height would become 60 m {by using s=ut+1/2 at*t formula} so P.E becomes mgh = 10*10*60= 6000 J.vel after 2 seconds is = 40-(10*2)= 20 m/sec hence K.E = 1/2 * m * V * v = 2000 J

electricityfor many of the energy servicesaround the house. Because of this, it is extremely important to have various safety devices to protect from fire and electrocution. Industrial electricity use has similar problems. This page examines these electrical safety devices. Namely, fuses, circuit breakers, and ground fault circuit interrupters. For more details, please go to the main articles.Both fuses and circuit breakers are the connection point between the electrical gridand an individual house.For more details please see connecting homes to the electrical grid.Fusemain articleA fuse is an electrical safety device that has the capability to protect an electric circuitfrom excessive electric current. It is designed to allow current through the circuit, but in the event that the current exceeds some maximum value it will open, SEVERING the circuit.Circuit breakerFigure 1: A circuit breaker box.Circuit breakers are devices that protect circuits from overload current conditions. They do the same job as fuses, but they are not DESTROYED when activated. They are more expensive to put in than fuses but since components RARELY need to be replaced, it may be cheaper in the long term. Circuit breakers are often considered safer since the USER can't as easily disable them (like putting the wrong size fuse in place).Circuit breakers functionally open a switchwhich turns off all the electrical currentbefore the EXCESS electrical current can start a fire. Before resetting the circuit breaker, always turn off or unplug the electronic devices that were being used with the breaker was activated.

e here's UR ANS hope it HELPS you THE other NAME of ELECTRIFIED wire is cable.

electricity is an imbalance of electric charges within or on the surface of a material. The charge REMAINS until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.A static electric charge can be created whenever two surfaces CONTACT and separate, and at least ONE of the surfaces has a high resistance to electric current (and is therefore an electrical insulator). The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for EXAMPLE, a PATH to ground), or a region with an excess charge of the opposite polarity (positive or negative). The familiar phenomenon of a static shock – more specifically, an electrostatic discharge – is caused by the neutralization of charge.
