Answer» Answer: The magnitude of force = 10⁻⁴ NExplanation: Correct Question : A force acts for 10 s on a body of mass 10⁻² kg initially at rest after which the force ceases come to an end to act. The body travels 0.5 m in the next 5 s. Find the magnitude of the force. Let the body starts from rest. ∴ u = 0Final velocity = distance / time⇒ Final velocity = 0.5/5 = 0.1 m/s ⇒ Final Velocity = = 0.1 m/sV = u + at⇒ a = (v-u)/tHere,
∴ a = (0.1 - 0)/10 ⇒ a = 0.1/10 ⇒ a = 0.01 m/s²Force(F) = Mass(m) × Acceleration(a)Here,
∴ F = 0.01 × 0.01 ⇒ F = 0.0001 N ⇒ F = 10⁻⁴ N |

Differences betwer speed and velocity |
Answer» YOUR ANSWERSPEED, being a scalar QUANTITY, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... On the other hand, velocity is a VECTOR quantity; it is direction-aware. Velocity is the rate at which the position changes.MARK AS BRAINLIEST |

An object is displaced by 10 meters in the direction of applied force. If the applied force is 55N, what is the work done by the force? |
Answer» Given :➨ Displacement = 10m ➨ Magnitude of force = 55N To Find :➳ Work done by applied force. Concept :⇒ Work done by force is DEFINED as the dot product of magnitude of applied force and displacement. ⇒ It is a scalar quantity having only magnitude. ⇒ SI unit : JOULE (J) MATHEMATICALLY, W = F▪d = FD cosΦ (Φ denotes angle between applied force and displacement) Calculation :➠ W = Fd cosΦ ➠ W = (55)(10) cos 0° ➠ W = 550 × 1 ➠ W = 550J |

Answer» With the help of the motion, the members draw attention of the Government to take SUITABLE action on a particular matter. The following are the types of motion: i) Adjournment motion ii) No-confidence motion RECTILINEAR, CIRCULAR AND PERIODIC MOTION - EXAMPLE Rectilinear Motion: Motion of the object in straight line path is called rectilinear motion. For example : Motion of train on TRACK, motion of ants in a straight path,motion of freely falling stone from top of the building towards the ground. Circular Motion: Motion of object in a circular path is called circular motion. For example: Children playing ringa ringa roses or moving in a circle, motion of Earth around the Sun. Periodic Motion : Motion of a object which repeats itself after a certain period of TIME is called periodic motion. For example : Motion of Earth around the sun is periodic as well as circular as it repeats it motion after time of 365 days. Motion of SIMPLE pendulum is periodic.Motion of minute and second hand in a WATCH is periodic. EXAMPLES OF DIFFERENT TYPES OF MOTION - EXAMPLE Sr.No. Types of Motion Examples 1 Rectilinear a)March past by the soldiers in straight line. b)Motion of falling objects from certain height 2 Circular a) Motion of satellites around planets. b) Motion of car turning to a curved track 3 Rotational a) Motion of giant wheel b) Motion of wheels of moving vehicle 4 Periodic a) Motion of simple pendulum b) Motion of Earth on its own axis. |
