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.

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:
