An alpha particle (the nucleus of a helium atom formed by 2 protons and 2 neutrons with charge q = +2(1.6 x 10-19 C ) is moving perpendicular to a magnetic field of 0.730 teslaat a velocity of 3.30E+6 m/s ; calculate the magnitude of the magnetic force exerted on it.
Calculate the acceleration of the alpha particle.
What will be the radius of curvature of the path followed by the alpha particle in the magnetic field?
What would be the force on the alpha particle if it were traveling parallel to the magnetic field lines?
In which scenario do you experience the larges acceleration? Explain why using physical principles you have learned.
how fast is the bag moving when the bults exits. If you wish to find the distance traveled using the equation d = 1/2 at2, what value should you use for a.
A star is moving away from the Earth at the speed of 200 km/s. What will be the wavelength of a spectral line that would have the wavelength of 500 nm if the star were at rest.
A child sitting 2.00 m from the center of a merry-go-round moves with a speed of 1.65 m/s. Compute the centripetal acceleration of the child (m/s), and the net horizontal force exerted on the child (N). (m = 29.0 kg).
suppose there are 500 billion stars in the galaxy. How does your answer change if there are only 110 civilizations instead of 1.2×10^4.
