Set up an ivp whose solution will give the temperature of the body described in the following problem at the end of t minutes.
a body, whose initial temperature is 50c, is placed in water whose temperature is kept constant at 20c. the body then cools at a rate (with its time unit in minutes) that is equal to one-fourth the difference between its temperature and the temperature of the water.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

The solid that is formed and usually sinks to the bottom of a solution is the
