universe started‚ the Doppler Effect‚ the age of the universe‚ the origin of the universe‚ red shift/blue shift and dark matter/dark energy. The Doppler Effect is a change in frequency and wave length of a wave. It’s caused by the change in distance between the thing creating the wave and whatever it’s measuring‚ seeing and hearing the wave. The universe was created over 14 billion years ago‚ by an abrupt explosion called “The Big Bang”. Our solar as we know it is thought to be 4.5 billion years old

he would use his earnings to buy alcohol and be with women. Wolfgang also loved to pull pranks on his friends‚ and‚ in short‚ have a good time. He loved fashion and dancing. Mozart also often burst into fits of anger if something upset him. For example‚ when speaking to higher ups‚ such as‚ Emperor Joesph the II‚ Rosenberg‚ etc. Mozart’s attitude towards serious matter was always very open and out the box. Silieri’s and many higher ups were sometimes questionable about giving Mozart new task because

One World: Motion Topic: Write an article that explores how the Physics of Motion is (or can be) used to solve a specific problem in a local or global context. Millions of people everywhere around the world make use of the principles of motion to travel up and down quickly within a tall building. The use of elevators has been around since ancient medieval times since then has grown from being powered by a hoist and winder to electric and hydraulic motors1. An elevator

Lab Conclusion When comparing the average speed results from part two of the lab and the definition of acceleration‚ you find similarities between the two. First‚ average speed is distance divided by time‚ and we use it to describe the motion of an object moving at changing speeds. We can see this from our lab results from the average speed of the marble traveling down the ramp‚ because it picks up speed. When the marble is released at the top of the ramp‚ the ball doesn’t have the same momentum

A golfer practising on a range with an elevated tee 4.9 m above the fairway is able to strike a ball so that it leaves the club with a horizontal velocity of 20 m s–1. (Assume the acceleration due to gravity is 9.80 m s–2‚ and the effects of air resistance may be ignored unless otherwise stated.) a b c d e How long after the ball leaves the club will it land on the fairway?

Prisons are places where people give up their freedom‚ privacy‚ control and sometimes even their dignity. Losing your minds in prison is a common occurrence due to the restriction of movement and isolation that many prisoners experience. There are many people around them but they feel alone because they are away from their friends and family. If they are in prison for a lesser crime or a crime committed out of necessity then they feel alone in their ideals because they consider themselves a “regular”

Projectile motion is the act of projecting an object into the air at an angle when a curved path is an object follows when thrown or propelled near the surface of the earth.For example: a thrown football‚ an object dropped from an airplane‚ or a bullet shot from a gun.Projectile motion may only be used to solve mechanics problems if the acceleration is constant.The
