Which statement explains the molecular changes that occur in an enclosed gas as the pressure increases and the temperature is held constant? 1. An increase in pressure causes particles to move closer together, increasing the volume.

2. An increase in pressure causes particles to move closer together, decreasing the volume.

3. An increase in pressure causes particles to move farther apart, increasing the volume.

4. An increase in pressure causes particles to move farther apart, decreasing the volume.

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
