Check the correctness of Equation wring dimension1) work done =mgh |
Answer» Solution :-We need to check the correctness of he equation , W = MGH by writing the DIMENSIONS Here , as we know that Dimension of work ( W ) is [ML²T-²] So, • [ML²T-²] = mgh By substituting the dimensions of mgh, we need to prove that LHS = RHS so the given equation is correct . Now taking RHS and proving Substituting the dimensions , • m → M • g → LT-² • h → L ⇒ M × LT-² × L ⇒ ML²T-² Now COMPARING with LHS → ML²T-² = ML²T-² • LHS = RHS Hence , the given equation is correct |

Why does glass dont show refraction? |
|
Answer» Answer: The glass doesn't show refraction as this light does not CHANGE MEDIUM, and also there is a change of medium from air to glass and back into the air. Because the glass is so THIN and because the light STARTS and finished in air, the refraction into and out of the glass causes little deviation in the light's original direction. Hope it helps you! |

4500 J of energy is used to raise an object with a mass of 50 kg to a height h .Calculate h |
Answer» Given :-To Find :-
We have to find the height (h) here and we know the formula of Potential Energy (P.E) = m × g × h In this, we have P.E , m & g and h isn't there So, we PUT the values and solve it → P.E = m × g × h → 4500 = 50 × 10 × h → 4500 = 500 h → 500h = 4500 → h = 4500/500 → h = 9 Thus, the height is 9 m |

A cell supplies a current of 1.8A through two resistors in parallel, when the resistors are in series the current is 0.6A. calculate the resistance. |
|
Answer» Answer: I HOPE IT'S HELPFUL TO YOU BRO.... The total resistance of a circuit connected to the given cell of emf 15 V is the sum of all the resistances from various sources like, resistors, ammeter, voltmeter, etc., connected in series along with the internal resistance of the cell. In this case, the total resistance is given as 3Ω+3Ω+6Ω=12ohms. From the ohm's law the total current can be calculated from the FORMULA I=V/R. That is, I= R V
= 12A 15V
=1.25A. Hence, the current through the battery is 1.25 amperes. The voltage output of a device is measured across its terminals and is CALLED its terminal voltage V. Terminal voltage is given by the equation V=emf−Ir. PLEASE MARK BRAINLIST...... PLEASE FOLLOW ME....... |

( 4 ) Circumcentre of an acute angled triangle is.....................of the triangle.(A) On one side(C) on one angle(B) in the interior(D) in the exteriorplz fast |
|
Answer» In the interior Explanation: CIRCUMCENTER of a triangle is formed by JOINING the perpendicular bisectors of three sides of triangle. As we draw perpendicular bisectors of three sides, they will intersect at one point(say O) which lies inside the circle. From that point of INTERSECTION, draw a circle touching each of the VERTEX of a triangle and we get a circumcircle. And O becomes centre of the circle. Hence, circumcenter lies inside the triangle. |

Application of work energy theorem |
|
Answer» Answer: see below.. Explanation: Work-Energy THEOREM is very useful in analyzing situations where a rigid body moves under several forces. As we know that a rigid body cannot store potential energy in its lattice due to rigid structure, it can only POSSESS KINETIC energy. Thus the work done by any force acting on a rigid body is EQUAL to the change in its kinetic energy. This is the basis of work energy equation for rigid bodies. |
