Which of the following describes a series circuit?
Bulbs are all in a loop
A stapler on a desk will not move unless someone or something exerts a force on it in some way
Newton's First Law
IS A "HEAT WAVE" A PHYSICAL WAVE
YES IT IS
AS YOU MOVE LEFT ON THE PERIODIC TABLE,THE ATOMIC NUMBER TENDS TO

IDENTIFY TWO TYPES OF ENERGY IN A CAMPFIRE
Thermal, chemical, light and sound
Which of the following describes a parallel circuit?
Current flows along each branch
for every force there is an equal and opposite force
Newton's Third Law
WHAT IS WAVELENGTH
THE DISTANCE BETWEEN SUCCESSIVE CREST OF A WAVE ESPECIALLY POINTS IN A SOUND WAVE OR ELECTROMAGNETIC
HOW ARE HOMOGENEOUS AND HOMOGENEOUS MIXTURES DIFFERENT
HOMOGENEOUS MIXTURES HAVE THE SAME COMPOSITION THROUGHOUT WHILE HETEROGENEOUS MIXTURES ARE DIFFERENT
The Law of Conservation of Mass
States that energy cannot be created nor destroyed, but it can change form
What type of circuit do we find in our houses
Parallel
A force that acts between surfaces that touch each other (resistance)
Friction
WHAT IS THE INTERFERENCE EFFECT
THE NET EFFECT OF THE COMBINATION OF TWO OR MORE WAVE TRAINS MOVING ON THE INTERSECTING OR COINCIDENT PATHS
WHEN BALANCING EQUATION,WHAT ARE YOU ALLOWED TO CHANGE

If there is elastic potential energy when a slinky is stretched and kinetic energy when it is moving, explain the energy transfer between potential and kinetic energy when it recoils to its original position. A. Stretched on a table-what kind of energy? Explain why
Since the slinky has not been released it has all stored potential energy.
What units does the electrical current have?
Amps
Anything that has mass and takes up space
Matter
What is a standing wave
HOW MANY PROTONS DOES Al
13
If coal is the cheapest energy source for making electricity, give three reasons why Sno Co Pud might not want to use very much of it?
1. Creates Acid Rain/Climate change
2. Causes lung diseases
3. Destroys the environment with the bi-products from burning including mercury
If there are 3 Resistors R1, R2 and R3 in series and V is total voltage and I is total current then Voltage across R2 is
V2 =I R2
= V R2/ R1 + R2 + R3.
