What is force ?school reopening ugh... |
|
Answer» ics, a force is any interaction that, when unopposed, will change the motion of an OBJECT. A force can CAUSE an object with mass to change its velocity, i.e., to accelerate. Force can ALSO be described intuitively as a push or a pull. A force has both magnitude and direction, making it a VECTOR quantity. |

Answer» Answer:Let the COST price at which Raju purchased be 'x'.It is given that he sold to Amit for a profit of 8%.\implies \boxed{x + \dfrac{8}{100} \times x = \text{Cost Price for Amit}}⟹ x+ 1008 ×x=Cost Price for Amit ⇒ 1.08x = Cost Price for Amit ...(i)Now Amit spends RS. 54 on REPAIRING and sells it to Nikhil for Rs. 1134 gaining no profit or loss. Therefore this means that, Amit sells it at the same cost with which he bought just by adding the additional REPAIR expense.⇒ Cost Price for Amit = SELLING price of Nikhil - Repair Charges⇒ Cost Price for Amit = 1134 - 54⇒ Cost Price for Amit = Rs. 1080 ...(ii)We know that Cost price of Amit = 1.08x (from (i))Equating (i) and (ii) we get:⇒ 1.08x = 1080⇒ x = (1080/1.08)⇒ x = 1000Hence the cost price for which Raju purchased the cycle was Rs. 1000 |

Explain projectile motion and derive equation of velocity of projectile at any time t |
|
Answer» Projectile motion is a form of motion EXPERIENCED by an object or particle that is projected near the EARTH's surface and moves along a curved path under the action of gravity only. This curved path was shown by Galileo to be a parabola, but MAY also be a line in the special case when it is thrown directly upwards. |

An engine supplies 196 joule of energy. If the energy is supplied to a weight of 500 gram, how high can it be lifted? (Given g = 10 m s-2).If 196 102 J of energy were used to raise a 20 kg boy above the ground, how high would he be raised ?When.2 |
|
Answer» : Energy supplied to the engine = 196 JMass of water = 500 gm = 500/1000 = ½ kg2Acceleration due to GROUND (G) = 10 mt/sec .Energy required for lifting water = mghH = energy supplied / m x g = 196 x 2 / 1 x 10 = 39.2 mt. |

Hello guys.. Answer the attachmentDont spam |
|
Answer» (a) Let the equilibrium of the test charge be stable. If a test charge is in equilibrium and displaced from its position in any direction, then it experiences a restoring force towards a null point, where the electric FIELD is zero. All the field lines near the null point are directed inwards towards the null point. There is a net inward flux of electric field through a closed surface around the null point. According to GAUSS's law, the flux of electric field through a surface, which is not enclosing any charge, is zero. Hence, the equilibrium of the test charge cannot be stable.(b) Two charges of same magnitude and same sign are PLACED at a certain distance. The mid-point of the joining line of the charges is the null point. When a test charged is displaced along the line, it experiences a restoring force. If it is displaced NORMAL to the joining line, then the net force takes it AWAY from the null point. Hence, the charge is unstable because stability of equilibrium requires restoring force in all directions.Explanation:I hope this is helpful |
