15. A beam of a partide passes undeflected through crossed electric and magnetic fields with electric field = 6.6 x 10°N/C and magnetic field = 1.27. Their speed in m/s will be​

Are aliens real? justify you’re answer.

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
