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.
All objects change velocity as they move toward earth at a rate of 9.8 ms2 due to which factor of gravity
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
Force can be calculated as pressure x area Which of the following will produce the most force
What creates the lift that allows gliders to fly
Unequal Pressure
The aircraft's wing is shaped so that the air passing over the
wing moves faster than the air under the wing causing a positive
pressure differential, thus creating lift. In simpler terms, it is
the air moving above the wing, not below the wing, that causes
lift.
What will happen if too much tension force is exerted on a spring
Which fundamental force contributes to pressure in both water and the atmosphere
What is the method used to produce nuclear energy in power plants
What best describes thermal energy
energy of molecular motion
For which of these would the buoyant force of air be greatest a bird hotair ballon an airplane
it would be the same for all
Which of these is a type of drag force turbulence tension thrust and compression
What following objects has the greatest density in grams
50 gram object that is 25 cm
³
What would be the change in velocity for a 10 gram object dropped from the roof of a 20 meter building if it takes 2 seconds to reach the ground Hint acceleration due to gravity is 98 ms²
In two seconds of fall, the speed increases 19.6 meters (64.4
feet) per second.
The magnitude of velocity increases by that amount, while the
direction of velocity
doesn't change.
What is the si unit for pressure which is equal to 1 n exerted over 1m 2
That unit has the special name "pascal".
