Explanation:
During a baseball game, a player’s ball hit into the outfield is modeled by the equation h = –16t2 + 65t. A bird flying across the field follows the path modeled by the equation h = 8t + 20. Let t be the time since the ball is hit and h be the height.
Hypothesis is a proposed explanation which is made on the basis of given experimental data taken as starting point for further investigation. All hypothesis test are conducted in a same manner fiollowing the four main steps:
1. State the hypothesis
2. Formulate an analysis plan
3. Analyzing the data obtained
4. Final step is to analyze the results
There are three types of variables taken in an experiment:
1. Independent variable: light, temperature, humidity
2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives
3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil
Heat from the sun moves through space by the process called <span>electromagnetic radiation.
H</span>eat moves<span> in three different ways. They are radiation, conduction, and convection. Radiation happens when </span>heat moves<span> as energy waves, which are called infrared waves, directly from its source to something else. This is how the </span>heat from the Sun<span> gets to Earth.
