Which law states that the total momentum does not change when it is transferred
The law of conservation states that the total momentum does not
change when it is transferred.
A desk weighs 500 N with gravity applying that force downward If you apply 275 N upward force and a friend helping you applies 275 N upward force what is the net force applied
What most influences whether or not an object will float
An object's density influences its buoyancy, thus determining
whether or not an object will float
Which type of force is exerted on the support ropes of a hammock when you lie in it
How is sound energy produced and transmitted
by vibration of particles and fluids.
Which factors must be known to calculate an object's gravitational potential energy
A speed boat is moving at a velocity of 25 ms runs out of gas and drifts to a stop 3 minutes later 100 meters away What is the rate of deceleration
Which force allows hot air balloons to fly
Buoyancy allows hot air balloons to fly.
What best describes thermal energy
energy of molecular motion
Which of these is a type of drag force turbulence tension thrust and compression
What following objects has the greatest density in grams

³
What infroemation is needed to calculate the amount of energy needed to heat a volume of water to some temperature
You need to know the amount of water (mass), how many degrees
you want to heat it up, and the specific heat of water. Then - if
everything is in compatible units - you must simply multiply the
three together.
What is the si unit for pressure which is equal to 1 n exerted over 1m 2
That unit has the special name "pascal".
