Answer:
The correct answer is D.
Explanation:
It is important to use the correct number of significant numbers when reporting the results of an experiment because they indicate the accuracy of the measurements. Significant numbers in measurement are those that provide fundamental information about uncertainty or accuracy of measurement.
Have a nice day!
Answer:
D
Explanation:
Scientists use significant figures to avoid claiming more accuracy in a calculation than they actually know.
Answer: a digital signal
Explanation:
a. 1/2 Potential Energy, 1/2 Kinetic Energy
b. 1/2 Potential Energy, 0 Kinetic
c. 100 Potential Energy
Point B:
a. 1/4 Potential, 3/4 Kinetic
b. 100 Kinetic, 0 Potential
b. 1/2 Potential, 1/2 Kinetic
Point C:
a. 1/2 Potential, 1/2 Kinetic
b. 3/4 Potential, 1/4 Kinetic
c. 100 Potential, 0 Kinetic
Answer
Answer:
The group that is exposed to the variable to be tested is called as experimental group.
Explanation:
An experiment consists of two kinds of group. They are experimental group and control group. The working of control group and experimental group are mostly same except that the variables will be changed in experimental group, while it is kept constant in control group. So at the end of experiments, the results from control group and experimental group are compared and the final outcome has been derived. So the given statement where the group is exposed to the variable to be tested or the independent variable is called as experimental group.
How do fission nuclear reactions differ from fusion nuclear reactions?
A. Fission reactions involve the conversion of matter into energy, but fusion reactions do not.
B. Fusion reactions involve the conversion of matter into energy, but fission reactions do not.
C. Fission reactions are used to generate electricity for consumers, but fusion reactions are not.
D. Fusion reactions are used to generate electricity for consumers, but fission reactions are not.
Answer:
C
Explanation:
Both fission and fusion are nuclear reactions that produce energy, but their applications differs.
Fission is the splitting of a large (heavy, unstable) nucleus into smaller ones, and fusion is the process where nuclei of small atoms are combine together to form the nuclei of larger atoms releasing vast amounts of energy.
The correct answer is c. Fission reactions are used to generate electricity for consumers, but fusion reactions are not.
The physics of fusion is the process that makes the sun shine, and that makes the hydrogen bomb explode.
