A) 5
Half-life is the time it will take for a quantity to reduce to half its initial value. In this case, uranium will undergo radioactive decay, and after 700 mil years, 5 of the 10 uranium atoms will have decayed.
The type of local anesthetic patch that would be indicated is Lipoderm.
<h3>What is Lipoderm?</h3>
- Transdermal delivery of drugs for pain, nausea, and veterinary usage has been accomplished with Lipoderm.
- When treating pain, several medications might be combined to focus on the many pain-causing factors.
- Lipoderm is a particularly efficient medicine delivery system for cats since it penetrates the inner ear skin.
- A patented liposomal component in Lipoderm, a chic substitute for conventional PLO gels, may improve the permeability of a number of active ingredients.
- In contrast to PLOs, which have a sticky feel, it is smooth and creamy to the touch.
- An anhydrous form of Lipoderm, PCCA has been developed for active pharmaceutical ingredients (APIs) that are unstable in water.

The Doppler radar used in weather forecasting measures the direction and speed, or velocity, of objects such as drops of precipitation. This is called the Doppler Effect and is used to determine whether movement in the atmosphere is horizontally toward or away from the radar, which aides in weather forecasting.
The only statement on the options that says true about density is:
> The density of an object determines whether it will sink or float.
Why?
Density is a physical property of an object.
Density is not derived as a unit of measure. It is derived from 2 fundamental units: kg and m.
The Density of an object is not constant.
Density is calculated by dividing the mass by the volume of an object.
Answer: Most rocks do not contain organic material-most fossils are not organic anymore. One of the most common isotopes used in radiometric dating is uranium-235 or U-235. ... This makes it useful for dating rocks that are very old. Radioactive isotopes with short half-lives cannot be used for dating old rocks.
not 100% sure :/
