The units of pressure are called derived units because it is derived from base unit, which is distance and a derived unit which is force. Force is derived from acceleration, a derived unit as well, and mass, a base unit; which makes it a derived unit.
Answer:
Magnification m is 2.5cm
Explanation:
This problem bothers on lenses
Given data
Object distance u= 4cm
Height of object v= 10 cm
The problem is quite straightforward seeing that object and image distances are given
We know that the magnification
m= size of image/size of object
m= v/u= 10/4 = 2. 5cm
What is a convex lens
A convex lens is a type of lens that has the centre thicker than the ends, the thickness at the centre makes the lens surface to curve outward. Convex lens causes close light rays of light to converge at a point after refraction.
The correct answer is A:) hope it helps :0
1. Domain.
<span>Info: Domain is the largest taxa, and there are only three domains: Archaea, Bacteria, and Eukarya. </span>
<span>As a rule of thumb the less number of members a taxa has, the broader spectrum of organisms it carries. </span>
<span>2. Specific epithet </span>
<span>Info: The Genus is Loxodonta (italicized), the family Elephantidae, the Domain's Eukarya. </span>

Answer:B=Negative C=Positive D=Positive
Explanation:objects that repel each other means they have the same polarity. objects that attract have the opposite polarity A is negatively charged if A and B repel then A and B are both negative. B is negatively charged if B and C attract then they have reverse polarity which makes C positively charged. C is positive if C and D repel then that means that C and D have the same polarity making D positively charged.
