Robert is accelerating a cart at the rate of 2.2 meters/second2. if the mass in the cart is doubled, and the net force is also doubled, what is the final acceleration? a. the acceleration is halved. b. the acceleration remains the same. c. the acceleration is doubled. d. the acceleration becomes zero. e. the acceleration is quadrupled.

Which of the following would not be taken into consideration when describing the quality of a sound

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
