Consider a double-fluid manometer attached to an air pipe shown below. If the specific gravity ofone fluid is 13.8, determine the specific gravity of the other fluid for the indicated absolutepressure of air. Take the atmospheric pressure to be 95 kPa
A race car enters the circular portion of a track that has a radius of 65 m. Disregard the 70 m in the picture. When the car enters the curve at point P, it is traveling with a speed of 120 km/h that is increasing at 5 m/s^2 . Three seconds later, determine the x and y components of velocity and acceleration of the car. I'm having trouble getting the correct y component of acceleration. all the other answers are correct. thank you!
