Your physics professor is foolishly standing out in a field during a thunderstorm and measures two bolts of lightning to hit two trees at opposite ends of the field at exactly the same time. you, being considerably less foolish, are driving by in a car on a road right next to the field at a speed v when the lightning bolts strike the trees, one of which is in front of the car, the other of which is behind it. you happen to line up with the professor right when he observes the lightning bolts strike the trees. as measured by you in the car, a. the lightening bolts appear to hit at dofferent times, but once you factor in your speed in the car, you will agree that the bolts hit the trees at the same time. b. the lightening bolts do not hit both trees. c. the lightning bolts hit the trees at the same time. d. the lightening bolts do not hit the trees at the same time.

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
