This would be a geocentric model.

It was proposed due to religion before the Renaissance in Italy, and was later replaced with the current heliocentric model.

You are riding on a carousel that is rotating at a constant 24 rpm. It has an inside radius of 4 ftand outside radius of 12 ft.
Nookie1986 [14]

Answer:

magnitude of the Coriolis acceleration is 44.235 ft/s² and the direction of the acceleration is along the axis of transmission

Explanation:

Given the data in the question;

Speed of carousel N = 24 rpm

From the diagram below, selected path direction defines the Axis of slip.

Hence, The Coriolis is acting along the axis of transmission

Now, we determine the angular speed ω of the carousel.

ω = 2πN / 60

we substitute in the value of N

ω = (2π × 24) / 60

ω = 2.5133 rad/s

Next, we convert the given velocity from mph to ft/s

we know that; 1 mph = 1.4667 ft/s

so

V_{slip = 6 mph = ( 6 × 1.4667 ) = 8.8002 ft/s

Now, we determine the magnitude of the Coriolis acceleration

a_c = 2( V_{slip × ω )

we substitute

a_c = 2( 8.8002 ft/s × 2.5133 rad/s )

a_c = 44.235 ft/s²

Hence, magnitude of the Coriolis acceleration is 44.235 ft/s² and the direction of the acceleration is along the axis of transmission

ICE Princess25 [194]

Answer:

The magnetic compass shows no deflection.

Explanation:

  • When a magnetic compass is placed on a current-carrying conductor, the compass needle shows deflection.
  • When the direction of the current is reversed, the needle deflects in the opposite direction.
  • This is due to the fact that the current-carrying conductor generates a magnetic field around it.
  • If the direction of the current is reversed, the magnetic polarization changes.
  • This phenomenon was first noticed by Oersted, and later it helped to develop electromagnetism.
