An electron circles at a speed of 13000 m/s in a radius of 2.37 cm in a solenoid. the magnetic field of the solenoid is perpendicular to the plane of the electron’s path. the charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. find the strength of the magnetic field inside the solenoid. answer in units of t find the current in the solenoid if it has 39.6 turns/cm.

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

What is the final velocity of the initial velocity of 25 and -50?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
