If heat is transferred between two objects, what has to be true about the situation

1. Calculate the total heat content of 10 kg of ice at - 23°C.? 2. How much heat is contained in 100 kg of water at 60.0 °C?

Which is the fastest way to send information using sound waves, light waves or water waves

a care starting from rest has an acceleration 0.3 m/s square, calculate the velocity and distance travelled by this car after 2 minutes?

A sand core used to form the internal surfaces of a steel casting experiences a buoyancy force of 225 n. the volume of the mold cavity forming the outside surfaces of the casting = 4840 cm3.

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.
