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 0.530 tesla at a velocity of 3.00E+6 m/s
A. calculate the magnitude of the magnetic force exerted on it.
B. Calculate the acceleration of the alpha particle.
C. What will be the radius of curvature of the path followed by the alpha particle in the magnetic field?
D. What would be the force on the alpha particle if it were traveling parallel to the magnetic field lines?
Torque can be calculated by multiplying the force (N) applied at 90 degrees to the lever arm at a distance (m) from the pivot point (point of rotation), the compound SI unit for the torque is N*m. If the force (at 90 degrees to the lever arm) appl..
A 2500 kg car rounds a flat curve of radius 75 m at speed of 80 km/h. if the pavement is icy and the force of static friction is 6000 n, what is the maximum speed the car could safely go around the curve
You have a wire with a current that points upwards. If you put a compass east of that wire, how would the magnitude and direction of the total magnetic field change
Sheena can row a boat at 2.95 mi/h in still water. She needs to cross a river that is 1.17 mi wide with a current flowing at 1.79 mi/h. Not having her calculator ready, she guesses that to go straight across, she should head 60.0° upstream.
As a spacecraft approaches a planet, the rocket engines on it are fired (turned on) to slow it down so it will go into orbit around the planet. how long (in minutes) must the engines be fired
One kilomole of an ideal gas undergoes a free expansion, tripling it's volume. What is the change of entropy of the universe
A metallic sphere has a charge of +3.7 nC. A negatively charged rod has a charge of -6.0 nC. find the charges of the sphere and the rod
Objects of equal mass are oscillating up and down in simple harmonic motion on two different vertical springs. The spring constant of spring 1 is 205 N/m. Find the spring constant of spring 2.
Find (a) magnitude and (b) direction of A - B. (Give the direction as a positive angle with respect to due east). Find out the (c) magnitude and (d) direction of B - A. (Give the direction as a positive angle with respect to due west).
In a football game a kicker attempts a field goal. The ball remains in contact with the kicker's foot for 0.0618 s, during which time it experiences an acceleration of 326 m/s2. The ball is launched at an angle of 57.3° above the ground. Determine..
Though slow on land, the leatherback turtle holds record for the fastest water speed of any reptile: 9.78 m/s. It is also among the largest of reptiles. Assume the largest leatherback yet discovered were to swim at the top leatherback speed. If its k..
An airplane travels x = 4.50 x 10^2 km due east and then travels an unknown distance y due north. Finally, it returns to its starting point by traveling a distance of r = 525 km. How far did the airplane travel in the northerly direction.
