Answer:
Explanation: Two possible solutions
in the absence of friction
mgh = ½mv²
h = v²/2g = 24.4²(2(9.81) = 30.344... = 30.3 m
if enough rolling friction exists to keep the ball from sliding, but ignoring air resistance and assuming the ball is already rolling smoothly at the start
mgh = ½mv² + ½Iω²
mgh = ½mv² + ½((2/3)mR²)(v/R)²
2gh = v² + (2/3)v²
2gh = (5/3)v²
h = (5/6)v²/g
h = (5/6)24.4²/9.81 = 50.5742 = 50.6 m
D. graduated cylinder used to find volume and triple beam balance used to find mass
E = I R
Voltage = (current)×(resistance).
V = 5A x 5 ohms = 25 volts.
Interstellar gas clouds are common in many galaxy, like the Orion nebulae which many young stars are being born. A typical nebula is many light years in diameter and contains enough material mass to make several thousand stars the size of our sun. The majority of the gas in nebulae consist of molecules of hydrogen and helium-but most nebulae also contain atoms of other elements. All known element in our periodic table is also being made inside this crucible of this immense hot gas. The source of the organic molecules is still a mystery. Irregularities in the density of the gas causes a net gravitational force that pull the gas molecules close together.
Answer:
B. is subject to a smaller net force but same acceleration.
Explanation:
F = m*a
So because our force applied is constant from the women pulling on the rope which means the acceleration is the same on both the 4kg create and the 6kg create. The only thing that changes here is the mass of the creates, so there is more tension force between the women and the 6kg create then there is between the 4kg create and the 6kg. It takes less force to move the 4kg create therefore the tension force is less between the two creates.
