Answer: B. 12.25 W
please give brainliest!
Explanation:
1) Force = Weight = 75 x 9.8 = 735 N
2.)Work = Force x Height = 735 x 5 = 3675 J
3.)Power = Work / Time = 3675 / (5 x 60) = 12.25 W
Answer:
Carbon dioxide is a chemical compound composed two oxygen atoms covalently bonded to one carbon atom. Carbon dioxide's molecular shape is linear. Also carbon dioxide exists in Earth's atmosphere as a gas. Carbon Dioxide- CO2 makes up one of the gases in our atmosphere.
Explanation:
Answer:
doublet
Explanation:
Proton MNR is used for the determination of no. of equivalents protons in a molecule
In the molecule, single NMR signal is produced for each set of protons.
Signal splitting is called spin-spin coupling and the splitting of signals depends upon the no. of neighboring proton.
The no. of signal for a proton is equal to n+1, where n is neighboring protons.
In 1-bromo-2-methylpropane, neighboring proton for both methyl protons are one. But the chemical environment of both the methyl protons are different.
Neighboring proton for methyl protons = 1
No. of signal for methyl protons = 1+1 =2
Hence, two doublets will be generated for each set of methyl protons. protons.
Matter needs to be in the state called a plasma. The sun is made of plasma, for example. A plasma is when the electrons have been stripped from the atoms.
