A: 2 hours
B: 3,200
To start you must find 10 percent of 2,000. That would be 200. now multiply 200 by 6 giving you the rate increased over 6 hours. That gives you 1,200. now simply add 1,200 to your original population of 2,000. That's your growth. Hope i helped! :)
The correct answer is D: Group 4.
A control group in an experiment is a group separated from the other groups, where the variable that is being tested cannot influence the results. In this case, different materials are the independent variable that you test. Effects of that independent variable on the melting rate of ice are excluded in the control group.
Answer:
10m/s
Explanation:
Given parameters:
Frequency of wave = 2Hz
Wavelength = 5m
Unknown:
Speed of the wave = ?
Solution:
The speed of a wave is derived from the product of wavelength and frequency;
speed = frequency x wavelength
Insert the parameters and solve;
speed =2 x 5 = 10m/s
It is right! Hope this works
Answer:
Carbon nanotubes (CNTs) are a virtually ideal reinforcing agent due to extremely high aspect ratios and ultra high strengths. It is evident from contemporary research that utilization of CNT in producing new cement-based composite materials has a great potential.
