What is the electric potential at 10 A° from a point charge 10`18 C in vacuum |
| Answer» POINT charges, such as electrons, are among the fundamental building blocks of MATTER. Furthermore, spherical charge distributions (like on a metal sphere) create external electric fields exactly like a point charge. The electric potential due to a point charge is, thus, a case we need to consider. Using calculus to find the work needed to move a test charge Q from a large distance away to a distance of r from a point charge Q, and noting the connection between work and potential (W = −qΔV), it can be shown that the electric potential V of a point charge is V=kQr (Point Charge), where K is a constant EQUAL to 9.0 × 109 N · m2/C2. | |

what is the heat energy generated across a 2 ohm resistor if 2 ampere current is passed through it for 2 seconds |
|
Answer» any ELECTRICAL appliance their is a simple RELATIONSHIP between the POWER output of a component, the potential difference across that component, and the current running through it. This is because charge times potential difference is energy, so (charge per unit time) times (potential difference) gives (energy per unit time). Thus, we have P=VI.Substituting V=IR from ohm's law, the power relationship can be rewritten as P=I 2 R. If the time factor is taken into consideration, then the power is calculated as P=I 2 Rt where t is the time taken in SECONDS to generate this power. From this FORMULA, the heat generated can be calculated as follows.In this case, a current of 2 A is passed through a coil of resistance 75 ohm for 2 minutes, that is, 120 seconds. Therefore, the heat generated is H=2 2 ×75×120=36000Joules. |

Answer» also the chain RULE but with less steps:CONSIDER (2x+1) is any variable and differentiate it the same way as you would differentiate y=x^nWhich is dy/dx = N*x^(n-1)So differentiation the main equation we get,dy/dx= 5*(2x+1)^4 * d(2x+1)/dx[The POINT to be noted here is after differentiating the BRACKET considering it as a variable, we need to again mulply with the differential of the bracket wrt x]So we get,dy/dx= 10*(2x+1)^4And that’s your answer…Do remember the following Chain Rule:dy/dx= (dy/da)* (da/dx)Hope it helps…Feel Good ;) |

a wire of resistance 9 ohm is cut into 3 equal peices which are joined to form a triangle. the equivalent resistance between any two vertices of the triangle is |
|
Answer» ntiating both SIDES with x —dy/dx = d(2x+1)^5 / dxApplying chain RULE —dy / dx = d(2x+1)^5/dx x d(2x+1)/d(2x+1)dy / dx = d(2x+1)^5 / d(2x+1) x d(2x+1)/ dxLike dy / dx * dc/dc = dy / dc * dc/dxdy / dx = 5*(2x+1)^4 x 2Thus answer is —dy/dx = 10* (2x+1)^4 |

Can a small force ever exert a greater torque than a larger force? Explain |
|
Answer» ANSWER: Yes, a small force can exert a greater torque than a large force. Torque equals the product of the force and the LEVER ARM distance. ... THEREFORE, if the lever arm distance is large ENOUGH, the torque EXERTED by the small force will be greater than that exerted by a large force with a small lever arm distance.oyee Mark as Brainialist!!! |
