A 0.361 T magnetic field in a mass spectrometer causes an isotope of sodium to move in a circular path with a radius of 0.077m. The charge on an ion is 1.60218x10^-19C. If the ions are moving with a speed of 10500m/s, what is the isotope's mass? Answer in units of kg. Please show work!!!!
A rocket blasts off vertically from rest on the launch pad with an upward acceleration of 2.30. At 10.0 after blastoff, the engines suddenly fail, which means that force they produce instantly stops.
A car is travelling at a constant speed of 31.1 m/s on a highway. At the instant this car passes an entrance ramp, a second car enters the highway from the ramp. The second car starts from rest and has a constant acceleration. What acceleration mu..

If the heavier fragment lands back at the equal point from which the shell was launched, where will lighter fragment land and how much energy was released in the explosion.
The base of the cloud, which is roughly parallel to the Earth's surface, serves as the negative plate and the region of Earth's surface under the cloud serves as the positive plate. The separation between the cloud base and the Earth's surface is ..
A hot (70°C) lump of metal has a mass of 250g and a specific heat of 0.25 cal/g°C. John drops the metal into a 500 g calorimeter containing 75g of water at 20°C.
A fishing line has attached to it a hollow plastic float 2.65 cm in diameter and having a mass of 1.50 g. Find the mass of a lead weight
Two circuits contain an emf produced by a moving metal rod, like that shown. The speed of the rod is the same in each circuit, other than the bulb in circuit 1 has one-half the resistance of the bulb in circuit 2.
