Now that we know the velocity of the cart before the collision is 1.80m/s, let's use this to determine the linear momentum and kinetic energy of the disk-cart system before the collision. The mass of the cart is 23.5kg. The mass of the disk is 11.

A circuit is built based on the circuit diagram shown. A diagram of a closed circuit with a power source on the left labeled 60 V. There are 3 resistors in parallel, separate paths, connected to it labeled 40 Ohms, 50 Ohms and 30 Ohms.

After harvesting their main crops, such as corn and wheat, many farmers plant a second crop called a cover crop. This cover crop grows during the fall and winter and is then plowed over in the spring. What is the main purpose of a cover crop? A.

A light wave is traveling straight up out of the ocean then moves out into the air how do you expect the movement of the light wave to change the light wave will

To verify that this expression for (vf) α has the correct units of velocity, you need to perform some unit analysis. begin by finding the equivalent of a volt in terms of basic si units.
