Answer:
1.5288 J
Explanation:
We can use the Energy conversion law
Energy can not be made or destroyed. It can only be converted to another form of energy
Potential Energy (PE) is the energy an object has due to its height of the location
<em>PE = mass * gravitational acceleration * height from the ground</em>
Simply here , lemming had a PE and KE also.
(g = 9.8 m/s²)
PE = 0.0780 * 9.8 *2
= 1.5288 J
Answer:
the correct answer is D.) 2,4
Answer:
D. Validity group
Explanation:
A validity group is not necessarily a component of a normal experiment.
A normal experiment is made up of the dependent variables, independent variables, and most times the control group.
- The dependent variable is one that relies on the outcome of the effect produced from the experimental design
- The independent variable is the one that causes a desired effect under the study.
- The control group is a group that does not receive any treatment nor attenuation of the conditions.
Answer:
Violet Light
Explanation:
On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.
