Answer:
Tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s
Explanation:
From the question above,
(1) tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s
Mometum = mass×velocity
Momentum = 270×0.5
Momentum = 135 kgm/s
(2) hare with a mass of 2.7 kg moving at a velocity of 7 m/s
Mementum = mass × velocity
Momentum = 2.7×7
Momentum = 18.9 kgm/s
(3) turtle with a mass of 91 kg moving at a velocity of 1.4 m/s
Momentum = mass × velocity
Momentum = 91×1.4
Momentum = 127.4 kgm/s
(4) roadrunner with a mass of 1.8 kg moving at a velocity of 6.7 m/s
Momentum = mass × velocity
Momentum = 1.8×6.7
Momentum = 12.06 kgm/s
From the above, the one with the greatest momentum is tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s
Heat is transferred from the sun-warmed surface of the earth to the cooler overlying troposphere via <u>conduction.</u>

<h3>Heat transfer from earth to atmosphere:</h3>
Conduction, convection, latent heating, and water phase transitions all help to carry heat from the Earth's surface, which has been warmed by the Sun, to the cooler troposphere above.
Latent heat flux is the worldwide transfer of latent heat energy via water and air currents. Here, we demonstrate how air circulation transports latent heat energy horizontally to cooler regions, where it condenses into rain or is deposited as snow, releasing the heat energy that was previously trapped there.
When air is heated from below by sunshine or by coming into contact with a warmer land or sea surface, convection occurs and the air below becomes less dense than the air above.

Answer:
a. The station is rotating at
b. the rotation needed is
Explanation:
We know that the centripetal acceleration is
where is the rotational speed and r is the radius. As the centripetal acceleration is feel like an centrifugal acceleration in the rotating frame of reference (be careful, as the rotating frame of reference is <u>NOT INERTIAL,</u> the centrifugal force is a fictitious force, the real force is the centripetal).
<h3>a. </h3>
The rotational speed is :
Knowing that there are in a revolution and 60 seconds in a minute.
<h3>b. </h3>
The rotational speed needed is :
Knowing that there are in a revolution and 60 seconds in a minute.
