The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). if an object’s mass is m=10. kg, what is its weight?

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

What is the role of lenses in microscopy?

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
