The radius of the garden hose is
, so its cross-sectional area is
The amount of water (in
) that comes out from the hose in one second is given by the product between the speed of the water and the cross-sectional area of the hose:
The time needed to fill the pool is equal to the volume of the pool divided by the amount of water that comes out every second:
Answer: A planet orbit is a gravitationally curved path that a celestial body travels around a point in space.
Explanation:
We define planet orbit as the path that a planet (or any other celestial object) has around two focal points (the orbit is an ellipse, the ellipses have two focal points). For example, the moon's orbit is around the Earth is almost circular, while Earth orbit is less circular. This movement is caused by the strong gravitational attraction of the sun, that keeps all the planets fixed in the orbits, this is why this is called a "gravitationally curved path".
the correct option is planet orbit.
Acceleration can be found using one of the following suvat equations:
Explanation:
The acceleration of an object is defined as the rate of change of velocity of the object:
where
v is the final velocity
u is the initial velocity
t is the time taken for the velocity to change from u to t
There are several equations used to find the acceleration of an object moving in a straight line (they are usually called suvat equation). Depending on which quantities are given in the problem, you can use one of the following equations:
where
is the acceleration
is the distance covered
is the time
is the initial velocity
is the final velocity
