A charged particle is injected at 153 m/s into a 0.0623-T uniform magnetic magnetic field perpendicularly to the field. The diameter of its orbit is measured and found to be 0.0467 m. What is the charge-to-mass ratio of this particle?
A singly charged ion of unknown mass moves in a circle of radius 14cm in a magnetic field of 8.2 T. The ion was accelerated through a potential difference of 9kV before it entered the magnetic field.What is the mass of the ion.
A standing wave on a 75.0cm long string has three antinodes. The Wavelength is .50m. If the string has linear mass density 3.78×10?5kg/m and tension 10.5N , what are the wave's frequency
minivan moving at 38 m/s passes an unmarked state police car moving at 24 m/s. The electromagnetic waves produced by the radar gun in the police car have the frequency of 8.25 × 10^9 Hz.
To get an idea of how empty deep space is on the average, perform the following calculations. Find the radius of a sphere of this volume in light years
Two cylindrical rods are identical, except that one has a thermal conductivity k1 and the other has a thermal conductivity k2. As the drawing shows.
A cylinder of radius a = 9.4 cm and height h = 9.5 cm is aligned with its axis along the y-axis as shown. What is the total flux ? that passes through the cylindrical surface? Enter a positive number if the net flux leaves the cylinder and a negat..
A 150-kg (including all the contents) rocket has an engine that produces a constant vertical force (the thrust) of 1680 N, Find the acceleration of the rocket
A car makes a round trip for 100m in 10 seconds. What is the average velocity?
A 77 person stands on the uniform ladder 4.0 long, that weighs 100. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only the normal force.
Two point charges, q1 = -12.5 ?C and and q2 = +18.7 ?C, are placed at two of the corners of a right triangle with a = 23.5 cm, Find the magnitude of the electric field at the third corner of the triangle
A grocery cart is pushed along an aisle by a shopper who exerts a constant horizontal force of . The acceleration of gravity is . If all frictional forces are neglected and the cart starts from rest, illustrate what is the grocery cart’s final s..
The vertical component of this force is 128 newtons, as the horizontal component is 145 newtons. Calculate the magnitude of F.
