9.Compare the power used in the 2 Ω resistors in each of the following circuits: (i) a 6 V battery in series with 1 Ω and 2 Ω resistors, and (ii) a 4 V battery in parallel with 12 Ω and 2 Ω resistors |
|
Answer» -----(i) 6 V battery in series with 1 Ohm and 2 Ohm resistors1 Ohm and 2 Ohm resistors are connected in series. This current will flow through each component of the CIRCUIT because there is no division of current in series circuits. HENCE, the current FLOWING through the 2Ohm resistor is 2 |

Work done on equipotential inside a conductive sphere |
| Answer» TION:An equipotential surface is one in which all the points are at the same electric potential. If a charge is to be moved between any two points (say from point A to point B) on an equipotential surface, according to the formula dW=q⋅dV, the WORK done BECOMES zero. | |

A battery of 9 V is connected in series with resistors of 0.2 Ω, 0.3 Ω, 0.4 Ω , 0.5 Ω and 12 Ω, respectively. How much current would flow through the 12 Ω resistor |
|
Answer» Explanation:According to Ohm’s lawV= IRTherefore, I= V/RWhere,R is the EQUIVALENT resistance of resistances 0.2 Ohm, 0.3 Ohm, 0.4Ohm, 0.5 Ohm and 12 Ohm.These are connected in series.Hence, the sum of the resistances will give the value of R.R= R1 + R2 + R3 + R4 + R5= 0.2 + 0.3 + 0.4 + 0.5 + 12 = 13.4 OhmThe potential difference, V= 9 VI = 9/13.4 = 0.671 AWHEN resistors are connected in series, the current is the same in all the resistors. Hence, current in 12 Ω resistor = 0.67 A. |

What will be the resultant force when two force act in opposite direction |
|
Answer» If TWO forces of equal strength act on an object in OPPOSITE directions, the forces will cancel, resulting in a net force of zero and no movement. equal to the sum of the two forces. ... The FINAL force and its DIRECTION are called a resultant. |
|
| 66426. |
What is the resultant force when two forces act in same direction? |
|
Answer» When TWO forces act on an object in the same direction the forces ADD up to PRODUCE a large force. The magnitude of the two forces in the same direction is added to get the resultant force. For example, if f1 and f2 are the two forces acting on an object, the resultant force F= f1 + f2. |

What is the effect of force on shape of an object ??? |
|
Answer» Explanation:Effects of Force. A force acting on an object CAUSES the object to CHANGE its shape or size, to start moving, to stop moving, to ACCELERATE or decelerate. When there's the INTERACTION between TWO objects they exert a force on each other, these exerted forces are equal in size but opposite in direction. |

Which is the most reactive solid element? |
|
Answer» An element's reactivity is based on how many electron shells it has. The more electron shells, the less magnetic attraction to the nucleus the electrons on the outer shells have. Therefore, they can easily travel to other chemically attractive ATOMS (chemically attractive meaning that their outer electron shells are incomplete and only need one or two more or less electrons to be complete.)As you may know, the further down you go (along the y axis), the more electron shells the elements have and apart from the noble gases, the TRANSITIONAL metals are the least reactive group on the periodic table (due to having moderately balanced outer shells) which are situated towards the centre of the table. Therefore, the farther you go from those elements, the reactivity of the elements increase.Alkali metals (situated far away from transitional metals and noble gases) are the most reactive elemental group. Cesium is second from the bottom of this group, with 6 electron shells, so it fits all the CHARACTERISTICS of a reactive atom, therefore making it the most reactive element. |

What is circular motion |
| Answer» ICS, CIRCULAR motion is a movement of an object along the circumference of a circle or rotation along a circular PATH. It can be UNIFORM, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation. | |
| 66439. |
obtain equation of acceleration for uniform circular motion? Shiw that it's direction towards centre ? |
|
Answer» :- Acceleration that does not change in time is uniform, or CONSTANT, acceleration. The equation relating initial velocity, FINAL velocity, time, and acceleration is vf=vi+at.Explanation:If an OBJECT's SPEED (velocity) is increasing at a constant rate then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn't have uniform acceleration. |
