how do i calculate the magnetic flux if a solenoid with a cross-sectional area 0.10m^2 and it is linked by a magnetic field of flux density of 2.0x10^-3 and has 250 turns?

Protons and neutrons are found within the nucleus of an atom

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?
