Which statement accurately describes quantum mechanics and nanotechnology?

Liquid can flow but solid cannot give reason

Airida [17]

Answer:

well..

Explanation:

Liquid can flow but solid cannot because of differences in their properties

property of liquid which lets it flow:

inter-particular space is large
inter-particular attraction is small these properties tend to make the molecules of liquid free to flow

property of solid which tends to obstruct flow:

inter-particular space is small and so it's compact
inter-molecular attraction is strong hence no tendency to flow

Hope this helps!

When you pedal a bicycle, maximum torque is produced when the pedal sprocket arms are in the horizontal position, and no torque

poizon [28]

Answer:

This is because when the pedal sprocket arms are in the horizontal position, it is perpendicular to the applied force, and the angle between the applied force and the pedal sprocket arms is 90⁰.

Also, when the pedal sprocket arms are in the vertical position, it is parallel to the applied force, and the angle between the applied force and the pedal sprocket arms is 0⁰.

Explanation:

τ = r×F×sinθ

where;

τ is the torque produced

r is the radius of the pedal sprocket arms

F is the applied force

θ is the angle between the applied force and the pedal sprocket arms

Maximum torque depends on the value of θ,

when the pedal sprocket arms are in the horizontal position, it is perpendicular to the applied force, and the angle between the applied force and the pedal sprocket arms is 90⁰.

τ = r×F×sin90⁰ = τ = r×F(1) = Fr (maximum value of torque)

Also, when the pedal sprocket arms are in the vertical position, it is parallel to the applied force, and the angle between the applied force and the pedal sprocket arms is 0⁰.

τ = r×F×sin0⁰ = τ = r×F(0) = 0 (torque is zero).
