15. While playing the game of basketball, an experienced player often uses the conceptsof projectile motion. Such a player knows that she/he should properly adjust theangle of projection (0) of the ball when the ball is released with a certain velocity, u.This adjustment has to be done so that the vertical distance, travelled by the ball,in a time to equals the vertical separation between the basket and the point ofprojection. Also, in the time to» the ball should travel a horizontal distance equal tothe horizontal separation between the basket and the point of projection.(1) For a given speed of projection, the horizontal distance, covered by the ball, hasits maximum value when the angle of projection equals(a) 45 (b) 9030 d) 60(2) The time, T, taken by the ball to reach the point of maximum height above itspoint of projection equals :(a) u 81n6 (b) ug sin(C) 8Sin (d) sin63) Por a given speed of projection, the maximum horizontal distance, covered bythe ball, is the same when its angle of projection is either:(a) 45° or 75°(b) 15° or 75°(c) 30° or 75°(d) 60 or 754) The maximum height Hay reached by the ball equals :(a)sino8b) sin-e(c) sin 8(d) u sin" 08(6) During its flight' after being released by the player, the trajectory of the balli8(a) an are of a circle(b) a straight line(c)a parabolic path(d) a part of an ellipitical path |

Relation between physical quantity and moment of inertia |
|
Answer» Answer: The physical quantity that measures the inertia of a body is its mass. More the mass of an OBJECT, more will be its inertia.The MOMENT of inertia is a physical quantity which describes how easily a body can be rotated about a given axis. Here, torque and angular VELOCITY are the angular ANALOGUES of force and velocity, relating to moment of inertia in the exact same way that force and velocity relate to mass. |

Draw a neat diagram of half wave rectifier and explain its working. |
|
Answer» A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The PROCESS is known as rectification. Construction and working of half wave rectifier: If an alternating voltage is applied across a diode in series with a load, a PULSATING voltage will appear across the load only during the half cycles of the ac input during which the diode is forward biased. Such rectifier circuit, as shown in Fig(a). is called a half-wave rectifier. The secondary of a transformer supplies the desired ac voltage across terminals A and B. When the voltage at A is positive, the diode is forward biased and it conducts. When A is negative, the diode is reverse-biased and it does not conduct. The reverse saturation current of a diode is negligible and can be considered equal to zero for practical purposes. (The reverse breakdown voltage of the diode must be sufficiently higher than the PEAK ac voltage at the secondary of the transformer to protect the diode from reverse breakdown.) Therefore, in the positive half-cycle of ac there is a current through the load resistor and we get an output voltage, as shown in Fig(b), WHEREAS there is no current in the negative halfcycle. In the next positive half-cycle, again we get the output voltage. Thus, the output voltage, though still VARYING, is restricted to only one direction and is said to be rectified.

What would be the shape of the path of motion of the athlete duringjumping in air? |
|
Answer» Answer: Please mark me as brainliest Explanation: he whole POINT of the long jump is to jump as far as possible. A jumper Contents 1 Introduction 2 Phases 3 Run up 4 Take Off 5 Flight 6 Landing runs down the runway, launches themselves into the air, and then proceeds to fly through the air toward the landing pit (Figure 1). The WAY that the jump is measured is from the take off board to the mark in the sand that is closest to the take off board. Knowing this, we can classify the long jump as a projectile motion activity. Like many projectile motion activities, there is no need to worry about air RESISTANCE and drag force as we are evaluating the science behind long JUMPING, as the jumper is not moving fast enough to create a force that will have an impact. This means that our jumper will be traveling via uniformly ACCELERATED motion. Looking more in depth into the phases and science of the long jump will give us a better idea of why we don't need to worry about air resistance and what we can do to make our jumps further and better. |

Answer» Answer: In physics, ESCAPE velocity is the minimum speed needed for a free, non-propelled object to escape from the GRAVITATIONAL influence of a massive body, that is, to EVENTUALLY REACH an INFINITE distance from it. Escape velocity rises with the body's mass and falls with the escaping object's distance from its center. Explanation: #its jyotika |

Answer» Figure 1. The heat Q transferred to cause a temperature CHANGE depends on the magnitude of the temperature change, the mass of the SYSTEM, and the substance and phase involved. (a) The amount of heat transferred is directly proportional to the temperature change. To double the temperature change of a mass m, you NEED to add twice the heat. (b) The amount of heat transferred is also directly proportional to the mass. To cause an equivalent temperature change in a DOUBLED mass, you need to add twice the heat. (c) The amount of heat transferred depends on the substance and its phase. If it takes an amount Q of heat to cause a temperature change ΔT in a given mass of copper, it will take 10.8 times that amount of heat to cause the equivalent temperature change in the same mass of water assuming no phase change in either substance. |
