What is the most likely reason that a hypothesis would be useful even if experiments show that is false

Do you agree or disagree with the theories about the permian triassic extinction

Q6) A speed skater moving to the left across frictionless ice at 8.0 m/s hits a 5.0-m-wide patch of rough ice. She slows steadily, then continues on at 6.0 m/s. What is the magnitude of her acceleration on the rough ice?

A 58.1 kg wood board is resting on very smooth ice in the middle of a frozen lake. A 48.3 kg boy stands at one end of the board. He walks from one end of the board to the other end with a velocity of 1.

Explain this statement: "In a static situation, the electric field at the surface of a conductor can have no component parallel to the surface because this would violate the condition that the charges on the surface are at rest.

What kind of cell is in a dragonfly? A eukaryotic or prokaryotic?

A single-turn circular loop of wire of radius 65 mm lies in a plane perpendicular to a spatially uniform magnetic field. During a 0.10 s time interval, the magnitude of the field increases uniformly from 350 to 650 mT.

An ice skater has a moment of inertia of 5.0 kgm2 when her arms are outstretched. at this time she is spinning at 3.0 revolutions per second (rps). if she pulls in her arms and decreases her moment of inertia to 2.

What is the use of infrared rays?

What would be the acceleration of gravity of a planet with four times the mass of Earth but twice the radius?
