Well, i would tell the kid that light is electromagnetic radiation which
is visible. The frequency and wavelength is just right so the radiation
becomes visible, and that visible radiation goes away from the star and
reaches earth
It also depends on the age of the child and the comprehension level
Answer:
6000 cm<em>²</em>
Explanation:
let width of rectangle = 
Using Pythagorean theorem,
+<em> 50² = 130²</em>
<em />
<em> = 130² - 50² </em>
<em />
<em> = 14400</em>
<em />
<em>= 120 cm</em>
area of rectangle <em>=</em> length x width
<em>=</em> <em>120 x 50</em>
<em>= 6000 cm²</em>
Is an underwater mountain range
Answer:
B) the decay rates of radioactive uranium and lead
Explanation:
The radioactive decay is modeled using an exponential function with an essential parameter, namely the decay rate. The two rates (for urianium and lead) allow her to determine the number of years that passed since the time the zirconium was formed.
Potential energy is present in the river water behind a dam.
<h3>How is potential energy defined?</h3>
- Potential energy is a form of stored energy that is dependent on the relationship between different system components.
- When a spring is compressed or stretched, its potential energy increases.
- If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy.
- The object's mass, its mass in relation to some reference points, and the gravitational field it is in all affect the potential energy of the object.
- Joule is the SI unit of potential energy as a result (J)
- As weight and height increase, gravitational potential energy rises.
