Two coils A and B is provided to you whereas coil A has 30 turns and coil B has 50 turns. Which coil will exhibit more magnetic field. Why? |
|
Answer» o circular coils A and B are placed close to each other, and the current in the COIL A is changed then some current will be induced in the coil B and the magnetic field associated with it also changes. Thus the magnetic field around coil B also changes. This change in the magnetic field LINES around coil B INDUCES an ELECTRIC current in it. This process is known as electromagnetic induction. |

a projectile is fired with velocity u making an angle theta with the horizontal. its kinetic energy at the highest |
|
Answer» :A particle is FIRED with velocity u making an θ theta with the horizontal.We have to find kinetic energy of object at the highest point★ A body is SAID to be projectile if it is projected into space with some initial velocity and then it continues to move in a vertical PLANE such that its horizontal ACCELERATION is zero and vertical downward acceleration is equal to g.In projectile motion, the kinetic energy is maximum at the point of projection or at the point of reaching the ground and is minimum at the highest point.In projectile motion, velocity of object at the highest point of parabolic path is u cosθwhere u denotes initial velocity ➝ K = 1/2 mv²By SUBSTITUTING v = u cosθ➝ K = 1/2 m(u cosθ)²➝ K = 1/2 mu² cos²θ➝ K = Ko cos²θwhere Ko denotes kinetic energy of object at initial point of projection. |

3 examples of kinetic energy converted to potential energy |
|
Answer» tion:POTENTIAL ENERGY. KINETIC energy can be stored. ... In these two cases, the kinetic energy is converted to potential energy because while it is not actually doing WORK, it has the potential to do work. If we DROP the object from the shelf or release the spring, that potential energy is converted back into kinetic energy |

The cyclist goes around a circular tracks onces every 2 minutes. If the radius of the circular tracks is 105m, then his speed is |
|
Answer» :Time taken by cyclist to complete a round = 2 minRadius of circular path = 105 mWe have to find speed of cyclist★ Speed is DEFINED as the ratio of total distance travelled to the total time taken.It is a scalar quantity having only magnitude.It can't be negative or zero.SI unit : m/sAfter completing ONE round of circular path, distance covered by cyclist will be equal to the perimeter of circle.Distance travelled :➝ d = 2πr➝ d = 2 × 3.14 × 105➝ d = 659.4 mSpeed of cyclist :➝ V = d / t➝ v = 659.4 m / 2 min➝ v = 659.4/120 m/s➝ v = 5.5 m/s |
