The elements required for a fire to start are oxidizing agent, heat, and fuel.
The oxidizing agent is usually oxygen - when there is a lot of air, of oxygen, a fire can broke out more easily if the conditions are right - if there is no oxygen, the fire won't start - we put out a fire by depriving it of oxygen. Next, you need some heat and fuel to start a fire, which can all be seen in this triangle.

A(n) 60.3 g ball is dropped from a height of 53.7 cm above a spring of negligible mass. The ball compresses the spring to a maxi
Feliz [49]

Answer:

271.862 N/m

Explanation:

From Hook's Law,

mgh = 1/2ke²............... Equation 1

Where

m = mass of the ball, g = acceleration due to gravity, k = spring constant, e = extension, h = height fro which the ball was dropped.

Making k the subject of the equation,

k =2mgh/k²....................... Equation 2

Note: The potential energy of the ball is equal to the elastic potential energy of the spring.

Given: m = 60.3 g = 0.0603 kg, g = 9.8 m/s², e = 4.68317 cm = 0.0468317 m, h = 53.7 cm = 0.537 m

Substitute into equation 2

k = 2(0.0603)(9.8)(0.537)/0.048317²

k = 0.6346696/0.0023345

k = 271.862 N/m

An object has a weight of 100 N on the surface of the Earth. If the object is moved to 2RE above the surface of the Earth, its w
baherus [9]

Weight of the object is defined as

W = mg

here

m = mass of object

g = acceleration due to gravity

now at the surface of earth

g = \frac{GM}{R_e^2}

so given that

mg = 100 N

now when it is moved to distance 2Re from the surface so its distance from the center of earth will be given as Re + 2Re = 3Re

so acceleration due to gravity will be given as

g' = \frac{GM}{(3R_e)^2} = \frac{GM}{9R_e^2}

so now weight is given as

W = m*\frac{g}{9}

W = \frac{100}{9} = 11.1 N

so now weight will be 11 N
