A 2.48-Ω resistor is connected across a 9.00-V battery. The voltage between the terminals of the battery is observed to be only 7.78 V. Find the internal resistance of the battery.

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

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
