How much work must be done on an electron to accelerate it from rest to a speed of 0.909c? Number i 0.00000000000003383 Units J

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?

Why do we not observe relativistic effects in our daily lives? O Because motion is relative. O Because you can't go back in time. Because the math is too hard. O We do observe relativistic effects in our daily lives. This is why time sometimes appears to pass more quickly than usual. O Because relativity only effects particles such as electrons & protons. O Because the speeds we move at are much less than the speed of light.

10. An electron is accelerated from rest through a potential difference of 2.5 x 10° V. (a) What is the relativistic kinetic energy of the electron? (b) What is the speed of the electron? (c) What is the total relativistic energy of the electron? Given that the magnitude of the charge of the electron is 1.602 × 10-19 C and the mass of the electron is 9.11 × 10-3! kg.

Spaceship A is moving toward the Earth at 0.80c, and spaceship B is moving away from Earth at the same speed, according to observers on a distant planet. At the same moment, very bright lights are turned on at the front of spaceship A and on the back of spaceship B. The light from a)Spaceship A reaches the planet before the light from spaceship B.   b)both ships reaches the planet at the same time.   b)either ship could reach the planet first, but there's no way to tell in advance.   d) Spaceship B reaches the planet before the light from spaceship A.
