Answer:
nuclear fusion
<h3>The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.</h3>
The correct answer is the Type of batteries
Explanation:
In an experiment, it is normal the researcher modifies one variable, in this case, the number of batteries (independent variable), and this variable affects the variable tested, in this case, the brightness of the bulb (dependent variable).
However, other factors or variables should be constant to guarantee the results are reliable. In this context, one factor that the student should keep constant is the type of batteries he uses because this is not one of the main variables and therefore it is not expected he changes this on purpose or this is affected by other variables. Moreover, by making any change the experiment can be negatively affected. For example, batteries might differ in their power capacity this can affect the brightness of the bulbs.
The time required to travel that distance at the given speed is determined as 15.84 seconds.
<h3>Time of motion</h3>
The time of motion of the person is calculated as follows;
Distance = speed x time
time = distance/speed
where;
- distance = 500 m = 0.31 mile
time = (0.31 mile)/(70 mph)
time = 0.0044 hr = 15.84 seconds
Thus, the time required to travel that distance at the given speed is determined as 15.84 seconds.
