A 10 lb. cat needs 31⁄2 tablets that each contain 6 mg of a drug. what's the equivalent dose in mg/kg?
mina [271]

Mass of cat = 10 lb

1 lb = 0.454 kg

So mass of cat is 4.54 kg

Number of tablets given to cat

N = 3\frac{1}{2}

Each tablet has 6 mg of drug

Total drug given to cat

Drug = 3\frac{1}{2} * 6mg

Drug = 21 mg

Now dose given to cat in mg/kg form

Dose = \frac{mass of drug in mg}{mass of cat in kg}

Dose = \frac{21mg}{4.54kg}

Dose = 4.63mg/kg

How long would it take to drive to alpha centauri (4.4 light-years away)?
oee [108]
A light year is a unit of length that is used to espress distances that are astronomical. It is equivalent to 5.9 trillion miles or 9.5 quadrillion meters. Light year is defined by the distance a beam of light would travel in one year. One light year is equivalent to the distance that light would travel in vacuum on one Julian year or 365 days as defined by the IAU or the  International Astronomical Union. So, one light year is traveled for 1 year here on Earth. So, in order to drive to the alpha centauri, you would take about 4.4 years to do so.

How does the size of oxygens nucleus affect the distribution
son4ous [18]

Answer:

The protons which are present are positively charged that attracts and pulls the electrons closer to the water molecule. Thus, the water molecule's negative charge is distributed all over the atom of oxygen, producing a substantial negative charge.

Explanation:

The nucleus of the oxygen atom is made up of 8 neutrons and 8 protons. The protons which are present are positively charged that attracts and pulls the electrons closer to the water molecule.

Thus, the water molecule's negative charge is distributed all over the atom of oxygen, producing a substantial negative charge. While, as electrons have drifted away from water molecules, the atom of hydrogen are left with just a partially positive charge.
