Answer:
Spring constant, K = 415.9 N/m
Explanation:
The period of vibration of a spring, T, is given by:
T = 2√m/K
Where m = mass of the body in kg, K = spring constant or force constant or elastic constant or stiffness in Nm-1
Making K the subject of the expression,
K = m(2)2/(T)2
K = 4m()2/(T)2
Where m = 0.38kg, = 3.14285714286, T = 0.19s
K = 4 x 0.38 (3.14285714286)2 / (0.19)2
K = 4 x 0.38 x 9.87755102043 / 0.0361
K = 15.0138775511 / 0.0361
K = 415.9 Nm-1
Mathematics was the tool which scientists used to prove their theories and ideas. Mathematics was able to prove whether an idea a certain scientists had was correct or whether it was wrong. With this they wre able to advance the field very rapidly.
Answer:
This is an example of an experimental design.
Explanation:
Experimental design in research involves controlling the variables in order to prove the hypothesis. In an experimental design there must be an experimental group, that in this case is the group that received an herbal supplement, and a control group, that was only administered placebo. By having a control group, both groups can be measured and compared at the end of the experimental phase, to measure the influence of the independent variable.
Answer:
you could report to the nearby police station for immediate executions or judgement
Answer:
Ben most likely has acrophobia.
Explanation:
Acrophobia is a word of greek origin. Derives from <em>Acros</em>, which means "summit", and <em>phobos</em>, which means fear.
Acrophobia is thus, the fear of heights. These can be a serious medical issue in certain situations, as for example, in the scenario described in the question in which acrophobia is affecting Ben so much that he quit his job.
