Which statements explain how a maglev train can reach over 300 mph? Choose THREE correct answers A. Repelling magnetic forces can lift or levitate a mag-lev train off the ground to minimize friction B. Electromagnet motors can increase speed more efficiently than motors with metal gears C. Attracting magnetic forces can liſt or levitate a mag-lev train off the ground to minimize friction D. Only repulsive magnetic forces can propel mag-lev vehicles forward

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
