Q1. SLAC, the Stanford Linear Accelerator Center, located at Stanford University in Palo Alto, California, accelerated electrons through a vacuum tube two miles long (it can be seen from an overpass of the Junipero Serra freeway that goes right over the accelerator). Electrons which were initially at rest were subjected to a continuous force of 2×10-12 newton along the entire length of two miles (one mile is 1.6 kilometers) and reached speeds very near the speed of light.
Q2. Assume you are an astronaut and you have been stationed on a distant planet. You would like to find the acceleration due to the gravitational force on this planet so you devise an experiment. You throw a rock up in the air with an initial velocity of 7m/s and use stopwatch to record the time it takes to hit the ground. If it takes 8.0s for the rock to return to the same location from which it was released, what is the acceleration due to gravity on the planet?
A Michelson interferometer uses light from glowing hydrogen at 486.1 nm. As you move one mirror, 530 bright fringes pass a fixed point in the viewer. How far did the mirror move.
What is magnitude of the speed of the boat
What is fraction of the diameter of the Sun
What should be the minimum initial speed of the dart so that combination makes a complete circular loop after the collision. find the minimum diameter of the raft that would prevent the diamond from being seen.
An ice block is pushed horizontally on a frictionless surface with initial velocity v0. At some point, it comes to the nearly semicircular bump with a radius R=0.42m and the height h=0.33m above the ground.
What will transform in terms of the observable properties of the black hole as this process continues
Driving in your car with a constant speed of 13 m/s, you encounter a bump in the road that has a circular cross section, as indicated in the figure. If the radius of curvature of the bump is r = 29 m, find the apparent weight of a 59-kg person in you..
The perspective provided by Multiple-Concept is useful here. The highest barrier that a projectile can clear is 15.60 m, while the projectile is launched at an angle of 23.0 ° above the horizontal. What is the projectile's launch speed.
Assume a constant upward slope of 32; calculate the horizontal and vertical components of the acceleration of a truck that slowed from 140 to rest in 7.3.
What is the physics behind everyday sayings
Calculate the shear stress of the crude oil at the walls, and plotting the velocity distribution graph for the same.
A car starts from rest and travels for 10s with a uniform acceleration of +2.4 m/s2. The driver then applies the brakes, causing a uniform negative acceleration of -2.0 m/s2.
