Around 2.8212 sec
Explanation:
Given the eqn x=1/2at^2+vot
your vo=0
39=1/2(-9.8)t^2
=7.95=t^2
=2.82sec
Answer: Element or Isotope
Explanation:
Transmutation of elements is the change that occurs when one chemical element is transformed to another, this happens during nuclear reaction or during radioactive decay.
When this happens, a different element or isotope is formed because there is a change in the proton or neutron within the nucleus of such element.
Answer:
H = 1.85 m
Explanation:
First, we will convert the height completely into inches. 1 feet contains 12 inches in it. Therefore:
H = (6 feet)(12 inch/1 feet) + 1 inch
H = 73 inches
Now, we will convert this height from inches to meters. 1 inch is equivalent to 0.0254 m. Therefore:
H = (73 inches)(0.0254 m/1 inch)
<u>H = 1.85 m</u>
In order for the statement to be complete, the word needed is the interferometer. It is an optical device whose application is to make to ray beams from the single beam of light. It is usually in the form of reflection to produce interference.
