Copyright is a form intellectual property protection.
This serves to protect the original works of authorship including literary,
musical, and dramatic works. This differs to patent since copyright is for
artistic works and patent is for inventions.
A copyright lifespan is equivalent to the life of the
author plus 70 years. The only circumstance in which the author loses the copyright
protection is when the product is sold to another person/company.
Answer: <span>The
author sells the work to another person/company</span>
Answer:
Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup.
Answer:
709415.584 g
Explanation:
This is a heat capacity problem. We use the formula below to calculate.
Q=mcΔT
where Q is the quantity of heat
m is the mass of substance
ΔT is the change in temperature of substance( T2-T1).
Q= 9.5MJ = 9.5*10^(6}J
C.P = 30.8J/(K.mol)
temperature of sodium increases by 10°C which means our final temperature in kelvin T2 will be 510K
initial temperature T1= 500K
m= Q/[c (T2-T1)]
m= 9.5*10^(6}/ {30.8(510-500)]
m= 30844.156 mol of Na
Converting to grams we multiply by the molar mass of Na.
molar mass of Na = 23
mass of Na= 30844.156 *23
=709415.584 g
I can help, pm me and i will help you on there if that's alright?
<span>The number of protons are different from the other element. Protons are what make an element that particular element, ans so that pretty much what distinguishes the atoms of one element from the atoms of another.</span>
