**Answer:**

Like all the planets in our solar system, Earth and Mars orbit the sun. But Earth is closer to the sun, and therefore races along its orbit more quickly. Earth makes two trips around the sun in about the same amount of time that Mars takes to make one trip.

Tectonic plates under the ground ,either go on top of each other or crash.

**Answer:**

circular motion

In surface waves, particles of the medium undergo a circular motion. They are neither longitudinal nor transverse, for in longitudinal and transverse waves, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction, respectively, relative to the direction of energy transport.

**Explanation:**

Hope this helps

The power is defined as the energy used divided by the time :

where E is the energy and t the time.

In our problem, the energy used is E=0.45 kWh=450 Wh while the time is t=6 h, so the power used by the fan is

**Answer:**

3984 rad

**Explanation:**

The angular speed of a rotating object is the rate of change of angular displacement of the object.

Mathematically, it is given by

where

is the angular speed

is the angular displacement

is the time interval

In this problem, we have:

is the angular speed of the tire

We want to know what is the angular displacement in one minute, so in a time interval of

Solving the equation, we find:
