I just broke up with my bf what do I do? Please help I need a friend. :-)

An aircraft performs a maneuver called an "aileron roll." during this maneuver, the plane turns like a screw as it maintains a straight flight path, which sets the wings in circular motion. if it takes it 35 s to complete the circle and the wingspan of the plane is 11 m, what is the acceleration of the wing tip

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

An object weigh 40n in air ,weigh 20n when submerged in water,and 30n when submerged in a liquid of unknown liquid density.what is the density of unknown of liquid?
