A passenger in a train accelerating smoothly away from a station observes that a child's yo-yo hanging by its string from a luggage rack makes a 10 degree angle from the vertical.

Kate gathered three boxes of the same size made of different materials: glass, clear plastic, and aluminum painted black. She placed them on a windowsill in the sun for an hour and then measured the warmth of the air in each box.

A flute plays a note with a frequency of 266 Hz. What is the speed of sound if the wavelength is 1.3 m? 102 m/s 205 m/s 346 m/s 692 m/s

What kind of conduction occurs when each section of the axolemma has to be depolarized to threshold in sequence along the entire axolemma for a current to spread down the length of the axon?

Why is it that the two possible faults wit inductors are short circuit and open circuit

A car rounds a 75-m radius curve at a constant speed of 18 m/s. a ball is suspended by a string from the ceiling the car and moves with the car. the angle between the string and the vertical is:

Emission of light from an atom occurs when an electron

Which is an example of transfroming potential energy to kinetic

Place the ball in the plastic bag, and twist the top so the ball is secure in the bag. Wrap the twisted portion with tape so it stays tight. Use the hole punch or scissors to poke a hole in the part of the bag that's above the ball.
