Answer: The discovery of Uranus <u>proved that planetary orbits are elliptical .</u>

Explanation:

Uranus was first observed by astronomer William Herschel accidentally while conducting survey of stars. A faint object was moving in front of stars.

Its path was consistent with Bode's law. Neptune was found later on through mathematical calculations. Geocentric theory was disproved earlier than its discovery. It did prove that planetary orbits are elliptical.

You happen to know that the coefficient of static friction between your patio table and the ground is 0.42. You decide you want

Deffense [45]

Answer:

If the force applied is larger than 185.2 N, yes.

Explanation:

In order to move the table, the pushing force must be larger than the frictional force. The frictional force is given by:

$F_f = \mu mg$

where

$\mu=0.42$ is the coefficient of static friction

$m=45 kg$ is the mass of the table

$g=9.8 m/s^2$ is the gravitational acceleration

Substituting,

$F_f=(0.42)(45 kg)(9.8 m/s^2)=185.2 N$

So, we are able to move the table if we push with a force larger than 185.2 N.

What is rotation and revolution

skad [1K]

When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution.
