Solar energy reached the earth at the rate of about 14000 W/m^2 of surface perpendicular to the direction of the sun. By how much does the mass of the sun decreases in each second? The mean radian of the earth's orbit is 1.5 x10^11m. The surface area of a sphere= 4πr²
a particle with a mass of m1 slides down a frictionless road from point A to the stationary state. This particle hits another m2=3m1-mass stationary particle at point B. The observed orbit is horizontal at point B. a) Find the range of values that the collision coefficient e can take to move the m1 mass particle upwards (B to A) after impact. b) To e=0.5, find the h* height of the m1 mass particle and the w distance that the m2 mass will take horizontally.
In a proton linear accelerator, protons are accelerated to have a kinetic energy of 520 Me. What is the speed of these protons? (The rest mass of a proton is 1.67 × 10-27 kg.)
The IKAROS spacecraft, launched in 2010, was designed to test the feasibility of solar sails for spacecraft propulsion. These large, ultralight sails are pushed on by the force of light from the sun, so the spacecraft doesn't need to carry any fuel. The force on IKAROS's sails was measured to be 1.12 mNmN. If this were the only force acting on the 290 kg spacecraft, by how much would its speed increase after 7.0 months of flight? Assume there are 30 days in each month.
Problem A new type of force was discovered by physicists with the following expression: a Fnew + Be* + 3x4 = - where alpha & beta are constants, and x is the position. The expression above was obtained from the interaction of a massless Hig gs Boson (a type of particle) and a black hole. Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do to achieve this feat? (For simplicity, consider that no energy is lost in the process) Solution To determine the work done we apply the following W = dx Evaluating the above, we get W = e for the limits from xị to Xf substituting x1 and x2 as the limits, the work done is expressed as W = | + Bl X1 ) ( x15 - x25 )
Problem 1) We consider the following system when placed in a uniform gravitational field (with acceleration g): An ordinary 2 dimensional pendulum of length l is placed at the edge of a disc of radius a. The disc rotates with constant angular velocity w. Neglect all masses apart from the mass m at the end of the 2D pendulum. mass n a) How many degrees of the freedom does the system have, after taking into account the presence of constraints? b) Find the Lagrangian for the system
Antimatter: When a particle and its anti-particle collide, energy and momentum are conserved. However, the particles can annihilate each other and produce two gamma rays - high energy photons. An electron and an anti-electron each have a rest mass of 9.11 × 10-31 kg. Suppose the particles are each accelerated to a speed of 0.98c in a particle accelerator with a length of 1543 m for a head on collision. (Each particle is moving at this speed with respect to the lab, and the particles are moving in opposite directions.) They collide head on and annihilate. What is the wavelength of the gamma rays produced in this collision?

1. Consider a mass m initially at rest at a large distance I from center of the earth (l>R the earth's radius). The mass m is released and falls toward the earth. (a) Calculate the speed of the mass as a function of its distance x from the center of the earth. (b) In the approximation that l>>R, how much time does it take for the mass m to reach the earth? Express your answers in terms of R, 1, g (acceleration at the earth's surface) and (for part a) x.
A newly discovered light positively charged particle has a mass of m and charge q. Suppose it moves within the vicinity of an extremely heavy (fixed in place) particle with a positive charge Q and mass M. When the light particle is xi distance from the heavy particle, it is moving directly away from the heavy particle with a speed of vi. a) What is the lighter particle's speed when it is xf away from the heavy particle?
