Convert 230 mL to liters?
.230 L
100
What is Newton's First Law?
Law of Inertia. An object in motion stays in motion and an object at rest stays at rest unless acted on by an unbalanced force. Ex. When a car stops quickly, everything in the car flies forward.
100
What is the equation for momentum? Answer: p= mv (momentum= mass times velocity)
p= mv (momentum= mass times velocity)
100
Which circuit only provides one path for current to flow through, series or parallel?
Series
100
What is pitch?
The frequency of a sound wave
200
What is velocity?
Velocity is speed in a given direction; speed and direction of a moving object.
200
What is Newton's Third Law?
Law of Action-Reaction. For every action, there is an equal but opposite reaction. Ex. Action - A book pushes down on a desk. Reaction - Desk pushes up on a book.
200
If an object is not moving, what is its momentum?
Zero
200
What is the SI unit for magnetic fields?
Tesla (T)
200
What is the name for the highpoint of a wave?
Crest
300
Convert 78 km to meters?
78000 meters
300
What is Newton's Second Law?
Law of Force and Acceleration. F =mass x acceleration.
300
An 8N force acts on a 5kg object for 3 sec, what is the impulse?
24
(J=Ft, J= 8*3= 24)
300
The speed of a transverse wave in a string is 15m/s. If a source produced a disturbance of 5.00 Hz. What is its wavelength?
3m
(v= fwavelength, 15= 5wavelength)
300
True or False: Is all light visible light?
True
400
What is speed?
Tells us the rate at which an object moves. Defined by the distance divided by time.
400
You push a 60 kg cart with a force of 200N. If static friction is .08, and kinetic friction is .05, how much force does it take to get the object moving?
29.4 N
400
What is the definition of power?
The rate at which work is done
400
What is a wave?
A wave is a rhythmic disturbance that carries energy through matter or space
400
Frequency of a photon with an energy of 2.7x10^-19 J?
4.07x10^14 Hz
500
What does this motion graph represent?
Time is increasing to the right, but it's distance does not change. It is not moving, we say it is at rest.
500
You push a 60 kg cart with a force of 200N. If static friction is .08, and kinetic friction is .05, how much force does it take to keep the object moving?
49 N
500
A machine performs 500 Joules of work over 100 sec, how much power does the machine have?
5 watts
(P= w/t, P= 500/100= 5)
