Lexy throws a dart with an initial velocity of 25m/a at an angle of 60 degrees relative to the ground. What is the approximate vertical component of the i ritual velocity?

True or false electronic machines with no moving parts experience friction and get hot because electricity is moving through the wires

I'm having trouble figuring out how to study for my science test, it's based off of everything we've learned but I'm afraid there's some things I misunderstood during the year that will effect me on the test, and suggestions?!!

The air over Earth's surfaces absorbs heat from the materials of Earth. In Section 3 of the experiment, the air over the sand the air over the water because sand water.
