PE = mass * height * 9.81
PE = 142 * 25 * 9.81
PE = 34825.5 J
Mainly because he was Johnny Carson's advisor and consultant

<span>The observation or measurement of physical properties of matter does not change its composition or its chemical nature. Other examples of physical properties include the infrared spectrum, attraction or repulsion to magnets, viscosity and opacity.</span>
Answer:
Option C
Explanation:
From the question we are told that:
Mass 
Radius 
Time 
Generally the equation for Tension is mathematically given by



Therefore
, toward the center of the circle
Option C
The correct answer is:
sixteen times
In fact, the distance between charge q and the source S is 1 unit. Instead, the distance between charge p and the source S is 4 units. The magnitude of the electrostatic force is inversely proportional to the square of the distance between the charge and the source:

where r is the distance. If we take the force between q and S as reference, we have r=1, so that

while the force between p and S is

Therefore, we see that the force exerted between q and S is 16 times the force exerted between p and S.
