Answer:

Oval Shaped almost.

Explanation:

Planets and orbits come in all type of shaped and sizes. But for the planets they are almost like a circular shaped planet/orbit.

Hope this Helps! :)

Answer:

Oval and Circle and alot of other shapes

Explanation:

Orbits come in different shapes. All orbits are elliptical, which means they are an ellipse, similar to an oval. For the planets, the orbits are almost circular. The orbits of comets have a different shape.

The take-up reel of a cassette tape has an average radius of 1.5 cm. Find the length of tape (in meters) that passes around the

Rudik [331]

Answer:

1.28 m

Explanation:

Given;

Radius, r = 1.5 cm = 0.015 m

Time, t = 19 s

Average angular speed = 4.5 rad/s

Consider a point when the tape is moving at a constant velocity along the circumference of the circular reel of radius r. The linear velocity v at this point is given by;

v = rω ----(1)

Where

v is the linear velocity of the circular motion

r is the radius of the reel

ω is the the angular velocity.

At a point the tap undergoes a linear motion before passing round the reel of the cassette. The linear velocity v at this point is given by;

v = L/t ----(2)

where;

v is the velocity of the linear motion

L is the length of the tape (distance covered by the tape)

t is the time taken

Equating equation(1) and equation (2)
